Coming Full Circle with Super White

|

My involvement with the natural stone industry began in a distinct moment in 2012. In the midst of a kitchen remodel, I was browsing kitchen discussions on the Houzz website, learning about grout and cabinet hinges and numerous other topics that suddenly were of urgent importance. 

Then a fascinating thread scrolled into view, asking, Anyone ever cover their marble with saran wrap for a party? I eagerly clicked into the lively discussion about a Super White countertop that had been etching unexpectedly. Would covering it in plastic wrap be a good solution? The resounding answer was no, it would not.

At that time, Super White was still relatively new on the scene and often mislabeled as a quartzite, leading to disappointment when it didn’t act like one. Hence, the urge to wrap it in plastic.

On my next visit to the slab yard, I spotted a slab of Super White. Swoon! That’s one gorgeous stone – a blend of white and cool greys arranged in a dynamic pattern reminiscent of a fractured ice floe. It was immediately obvious why the stone was a superstar, despite the nebulous problem with its identity.

The helpful salesperson gave me a sample and I went home to do some diagnostics. The stone didn’t scratch glass, which ruled it out as a quartzite. I put a single drop of diluted hydrochloric acid on the stone, expecting a slight fizzing action and an etch mark. But nope, the stone didn’t etch. That meant it wasn’t a calcite-based marble. Next up, the test for dolomite: I roughed up an area of the stone with a nail, then put a drop of acid on the bits of powdered rock I’d scraped up. Bingo! It fizzed – the stone is made of dolomite.

Dolomite is similar to calcite but it contains some magnesium in addition to calcium. Compared to calcite, dolomite is slightly harder and it etches more slowly. That makes a dolomitic marble somewhat more durable than “regular” marbles that are made entirely of calcite, but the difference is subtle. 

There’s one more complicating factor with identifying Super White. The rock has fractures that are filled with quartz. This happens when the rock breaks underground – usually due to some sort of tectonic stress – and then mineral-rich groundwater fills in the broken parts. Geologists call this texture a “breccia” and it’s what gives Super White its magnificent pattern of white marble fragments floating in a river of grey. These small areas of quartz may have led to the stone being mislabeled as a quartzite, but it’s not a quartzite by any stretch. The rock’s full scientific name is brecciated dolomitic marble. 

Marble is a stone that’s been beloved and useful through the ages, but it’s one that warrants careful consideration. The potential for etching and scratching can be a dealbreaker for some, but no problem for others – but either way, people need to be able to make an informed decision. The more that sales reps, fabricators, designers, and homeowners can learn about the properties of stone they’re considering, the happier everyone will be. 

I wrote up my findings in a post on Houzz in a thread called The lowdown on Super White, and woke up the next morning to find a half-dozen responses and questions. By the time I’d answered the follow up questions, several more appeared. Who knew that geologic descriptions of countertop stones would be such a hit? The thread soon reached its 150-post limit so I started another. It too quickly filled up so I started yet another, and another. I’d unexpectedly stumbled into a topic that seemed a good match for a geologist who happens to like kitchens.

Before too long I’d found the Marble Institute of America (now the Natural Stone Institute) and a happy collaboration was born. One of our first priorities was to delve into this very topic: The Definitive Guide to Quartzite. The popularity of marble and quartzite led to articles such as Telling White Stones Apart, that aimed to help people sort out the differences between similar-looking stones.

But there was one more element of that original post that was prescient. I wrote, “I swoon every darned time I pass by a slab of white marble. I just love it! But I will have to come up with another place to use it, like as a mantle or a countertop on a china cabinet.”

Fast-forward 12 years, and my dream built-in cabinet and bookcase was being installed, and I could finally carry out that vision. I still stop dead in my tracks every time I come face to face with a slab of white marble. It’s an exquisite material, made all the better because it comes naturally from the Earth. At last, I was admiring these beauties as a customer, not a scientist.

I checked out many different slabs, but honestly, there was never a doubt in my mind that I’d end up with Super White. It also happened to be the only white stone that my husband liked. I was able to find a remnant piece with a brilliant pattern of fracturing that was gloriously similar to the satellite images of sea ice that I use in my science writing for NASA. I stood in front of the slab and ran my fingers over the leathered surface, appreciating the texture of the marble blocks floating within the icy quartz veins. I felt so very lucky that it was finally time for a piece of glorious white stone of my own.

 

Can you tell which image is Super White and which is the spring breakup of Arctic Sea ice? The image on the left is Super White, and is about 10 inches across. The one on the right is a NASA satellite image of Baffin Bay from April 18, 2024, and it’s around 150 miles across.

Natural Stone Plunge Pools + Outdoor Features Are Making a Splash

|

As homeowners continue investing in relaxing outdoor spaces, many are adding plunge pools and other features to their backyards. “The request we get most frequently is to install natural stone on the outside of their plunge pools,” says Karen Larson, co-founder of New Hampshire-based Soake Pools. Her company works almost exclusively with salvaged stones for the exterior and coping of its plunge pools. “Many clients opt for natural stone along the outside and coping of their plunge pools to enhance their landscapes with the stone’s durability, texture, and natural beauty,” Larson adds.

Cold plunging has become popular in the last few years. A cold plunge involves submerging yourself into cold water for a few minutes. The water is 50 degree Fahrenheit or cooler and most people who want to try it start with 30 seconds and build up to five to 10 minutes at a time. Those who do it regularly (which could be daily or weekly), say it’s a non-medically focused way to relieve joint pain and inflammation. Others find the act relieves stress and boosts their overall mood.   

Active participants might not be wrong. According to the Mayo Clinic Health System, “research indicates that icy water may have a positive effect on recovery after exercise by reducing inflammation and soreness. It also may help build resiliency, restore balance to the nervous system and improve cognitive function and mood.”

Other Ways to Take the Plunge

There are other ways to make your backyard an oasis. Larson says natural stones such as granite, limestone, and slate can be used as a decorative agent or creatively added to outdoor landscaping projects like pathways, patios, or retaining walls.  

Natural stone is a great choice for nearly any outdoor remodeling project as it’s incredibly durable, has timeless appeal, and requires little to no upkeep, according to Aaron Brundage, director of operations at System Pavers. “With stones available in a wide array of shapes and colors, it’s easy to create a personalized look that complements the aesthetic of your home,” he says.

Brundage offers four ideas for those who want to update or upgrade their outdoor living spaces:

Walkways

One of Brundage’s favorite ways to incorporate natural stone into landscaping is to build a walkway. “Because stone is so durable, it will hold up well in any weather while creating a functional focal point that elevates the look of your yard,” he says. “You can use rounded coping stones to eliminate tripping hazards and give your walkway a finished look and pleasing aesthetic.”

Fire pits

Fire pits are another beautifully practical way to use natural stone in your outdoor space. “By building a cozy and inviting space for friends and family to gather, you’ll give yourself more reasons to get outside and unwind while enjoying the view,” Brundage says. “A natural stone fire pit has a look that’s as stylish as it is classic.”

Retaining walls

Retaining walls are a wonderful way to feature natural stone in your outdoor space with a look full of texture and warmth. “Consider building short stone retaining walls that define your space while giving guests more places to sit and hang out around your yard,” he suggests.

Outdoor kitchens

Some of Brundage’s top remodeling projects include creating gorgeous outdoor kitchens with natural stone. “Nothing looks more inviting than a built-in grilling station surrounded by stone counters that are just the right height for entertaining,” he says. “A professionally built outdoor kitchen that uses stones to their full potential is an investment in your home that adds lasting value while enhancing the way friends and family use your outdoors on a regular basis.”

Grounded in Natural Stone Furniture

Another way to incorporate natural stone into your backyard is through custom furniture. According to Amy Hovis, an award-winning landscape designer and principal/owner of Eden Garden Design, and owner of Barton Springs Nursery in Austin, Texas, whether it’s crafting custom furniture or enhancing landscape designs, natural stone plays a pivotal role in grounding the space and fostering a deep connection with the natural environment.

“From majestic landscape boulders to smaller ones utilized as bases for furniture, the use of natural stone allows us to seamlessly merge the boundaries between the outdoors and interior settings, imparting a sense of continuity and harmony,” Hovis says. “It also introduces an element of surprise and intrigue, elevating the overall aesthetic appeal.”

Many of us enjoy spending as much time outdoors as possible, especially when the weather cooperates. Creating a calming space makes it more appealing to get outside and stay outside. Whether it’s adding a plunge pool or other outdoor features, there is no shortage of opportunities to incorporate beautiful and long-lasting natural stone into the mix.

Harmony in Hue: Embracing 2024 Color Trends with Natural Stone Elements

|

Colors have a powerful impact on our overall health and well-being. There are easy ways to incorporate this year’s most popular colors and pair them with natural stone to create fresh spaces.

We asked an interior designer, creative director, and color experts to share how homeowners could pair this year’s color trends with different types of natural stones inside their homes.

“Natural stone, and specifically marble, can hold up to any of this year’s colors of the year, next year and well beyond,” says Julie Jordan, creative director and founder at J Jordan Homes, based in Hinsdale, Illinois.

Rather than consider the colors of the year as a trend and finding a natural stone that complements any year’s color trends, Jordan prefers to design spaces that only become “more cool” after each passing year. Natural stone passes the test of time. 

“Blue, grey, brown, or white, natural stone is the darling of so many spaces,” Jordan adds. She suggests natural stones such as Arabescato Corchia and Bronze Armani marble, or Blue Roma quartzite. 

Natural stone doesn’t need to be relegated to just kitchen counters or bathrooms. “There are so many amazing places to use natural stone,” says Jordan. She loves to incorporate different types of stone as fireplace surrounds, feature walls, and trims. These areas can be upgraded with natural stone to elevate a space. For an easy refresh, consider incorporating new paint colors or accent pieces that reflect trending colors. 

 

The Calming Hues of Blues

Sherwin-Williams’ Upward SW 6239 is “a breezy and blissful shade of blue that evokes the ever-present sense of peace found when slowing down, taking a breath and allowing the mind to clear,” according to the paint company. 

“Upward SW 6239 is a very versatile hue and can be applied in many spaces from kitchens and bathrooms to living and bedrooms,” says Sue Wadden, Director of Color Marketing at Sherwin-Williams. “The light and airy shade pairs well with white marble countertops in kitchen and bathrooms for a very sleek and refined aesthetic.”

Wadden also likes pairing the blue hue with darker stone options like bluestone, granite, or sandstone. “The cool undertones of the color pair perfectly with the silty stone profile,” she adds.

Scotti J. Campbell, an interior designer and owner of interior design firm SJC Design & Interiors in the Pacific Northwest, says Sherwin-Williams’ Upward is a soft shade of blue that begs to be paired with warm brass and white or creamy marble slabs or flooring to create elegant and timeless spaces. “White marble counters and/or flooring with Upward in a bathroom depicts calm refinement,” she adds. “Marbles with quiet veining and movement pair beautifully with this calm and slightly feminine shade. Create kitchens or bathrooms that feel like seaside holidays, with soft breezes flowing through linen drapery.”

Benjamin Moore’s Color of the Year is Blue Nova 824 which, according to the company, is “an intriguing blend of blue and violet that sparks adventure, elevates, and expands horizons.” It also pairs well with several types of natural stone.

“When selecting natural stone to pair with Blue Nova, this sumptuous mid-tone generally works well with lighter hues—particularly stone varieties with a crispness or cooler cast,” says Andrea Magno, Color Marketing and Development Director at Benjamin Moore. “For example, a Calacatta Lincoln or Olympian Pearl marble would make for a striking countertop when paired with Blue Nova; or Imperial Danby marble would make for an interesting pairing with Blue Nova, calling attention to the rust veining—a nod to a blue and orange complementary color scheme. A pale gray limestone, such as Fleuri or Sterling, would also work nicely adding softness to the overall look.”

Campbell agrees pairing Blue Nova with marbles can be a powerful combination. “Vibrant and energetic, Blue Nova adds a bold punch to blue, with a touch of violet that says, ‘I’m unique, I have flair and style,’” she adds.

Campbell recommends combining Blue Nova walls with gray marble countertops and flooring in a bathroom to create a space that makes a statement that is both calm and uplifting, soothing and charging. “Shades of gray stone temper the vibrance of the hue and add a touch of masculine calm energy that is timeless and modern at the same time,” she says. “The opposite of boring and quiet, Blue Nova infuses spaces with life. Blue Nova walls or cabinetry, with dark gray marble or granite countertops in a kitchen feels modern and fresh.”

She loves the idea of gold-toned and creamy marble counters or floors with this shade to evoke the feel of coastal life in the South of France. She compares the look to blue skies and seas, fields of lavender and wheat, and warm sand on the beaches.

Leveraging Color Trends

Most homeowners choose natural stone for their homes because it’s timeless, natural, and beautiful. Incorporating color trends through paint colors and other accents is an easy and fun way to update a space while taking advantage of the beauty of natural stone in one’s home.

Billie Tsien and Tod Williams credit their love of stone with their frequent visits to Rome. As Tod Williams Billie Tsien Architects | Partners, the pair has designed and built more than 40 buildings, a large percentage of which are made using natural stone. “We’re interested in solidity, place and character,” Williams says, with the ultimate goal of creating projects “that have a long lifespan, are meaningful to the community, and will be loved for centuries.”

Their choice to use natural stone is both practical and philosophical.

The Day to Day of Stone

With each commission come client wants and needs for certain materials. Cost plays a factor. Durability and permanence play a factor as do future maintenance, longevity, and return on investment. These are all part of the practical side of material selections.

“Stone,” says Williams, “is a really good and durable permanent material. You go into the cathedrals, synagogues, mosques — the floors are made of stone, and they’re usually a patchwork quilt with headstones embedded in it and so on. It actually becomes more rich over time. I never go into the Pantheon without being absolutely riveted by the floor and the different colors that are there and the way it wears. I love the wear.” Stone is also a “wonderful and protective shell. It gives an exterior dignity.”

Tsien says that they are passionate about maintenance and longevity. “The idea of longevity is not abstract,” she says. Tsien and Williams connect with maintenance people and ask questions: How long does it last? Can this be cleaned? Who will clean it, and how? “Longevity,” Tsien says, “is very much based on the care of the stone.”

 

Character Development

The other side to design decisions and material choices is the emotional. It is Tsien’s and Williams’ innate senses that give a project a feeling of calm and quiet or energy and movement.

Tsien says she has always believed in “the importance of ‘showing the hand.’ We don’t believe in having a perfect, smooth stone that all looks the same from piece to piece. We’re interested in stones that have a vivid character.” It’s an important quality but hard to define. Some of it comes from natural stone’s irregularities, its “defects” that are not truly defects. Stone is a material pulled from the earth that is perfect in its imperfection. But beyond that, Tsien and Williams feel stone’s character more deeply. Says Williams, character includes “the person who cuts it and dresses it, how it moves along from being extracted from the ground to its final place. Even that has its own specific character.” 

Choosing the right stone starts with quarries, where the couple spends a lot of their time. Williams likens quarrying to “farming building material.” He enjoys meeting the quarrier, he says, “because that person knows how best to remove the stone from the ground and where the best pieces are of a certain quality or character. As with purchasing vegetables from a farmer you might say, ‘Well, what’s good today? What stone do you feel is best at this time in this place?’ I think that anyone who really loves stone, likes that it came from a specific place.”

When he visits a quarry, Williams says he imagines the quarried walls as buildings. “They’re negative buildings. I look at the wall of the quarry that we’re using, for example, getting Granite Tapestry stone from Tony Ramos’s quarry. [Ramos is a stone carver and founder of New England Stone.] That 80-foot-tall wall in the quarry is a building. There’s inspiration there.”

The relationship with the quarriers is important. “An awful lot of the stone industry is family owned,” Williams says. “That has a special resonance for us. We [Billie and I] are both married and partners and that goes deep in our studio; we all work in essentially one room. There’s conviviality and kindness and a sense of family.”

Tsien adds that “one of the great things about the stone industry is that it is personal, unlike something that’s manufactured like sheetrock — you can’t actually go to the source of sheetrock and talk to the person who owns the sheetrock. Whether it’s a quarry in Europe or India or Western Massachusetts, it’s always about the people together with the material. For us, that’s a very rich relationship.”

Good quarrying practices are also important to them. “You want to make sure the quarry is tended to in such a way that it is actually good for the earth,” Williams says. “Maintaining an efficient quarry, with as little disturbance to the surrounding ecological and community conditions is deeply important in stone sourcing. So, the quarriers have the same responsibilities that we do to make buildings that are meaningful.”

Source Code

Many of their projects take five years from inception to completion. “Within the first six months,” Williams says, “we’re investigating the stone.” They look at stone for the exterior and interior of their projects. “As we get into the interiors, we might find that another stone comes forward, or we look at the same stone in a different finish. We like to have at least two to three different kinds of stone that are similar so that we can make sure the owner and contractor have a voice in the selection. From the outset, we learn as we go.”

They look first for stone that might be local to a project but what’s more important is to find the right stone that will accomplish the project’s goals. For the LeFrak Centre at Lakeside, a covered ice rink in Brooklyn’s Prospect Park, Williams says they wanted stone from New York but they couldn’t find what they wanted and got it from Canada. “We had it chopped in a particular way so that it would feel a little bit like it was done by hand years ago, or at least compatible with that. That’s a perfect example of where we couldn’t get the stone locally, but we could try to make sure it was grounded and quiet so that the landscape itself came forward.”

Tsien and Williams never demand that a client use a particular stone, but they will tell clients they have a strong preference for a material and offer their reasons for why it’s the best choice. “But our vision has to be their vision, and their vision has to be our vision,” Tsien says.

By way of example, Tsien recalls the design for the welcome center at the Frederik Meijer Gardens & Sculpture Park in Grand Rapids, Mich. The client wanted to use a “less expensive and more subtle stone which came from Minnesota versus a wild and crazy stone that came from Brazil,” Tsien says. “And so, we used the stone from Minnesota, and the project turned out to be beautiful, but in my heart of hearts I’m still curious what the result would be with the other stone.”

Williams and Tsien look at color and veining, often creating a “kind of tapestry of colors,” Williams says. He adds that they have a penchant for using dimensional stone. “I’m not interested in techniques that somehow try to thin out stone. Basically, we’re interested in the stone as an embodied material, something that has body; it should have depth both in meaning and dimension.” 

When asked if they ever disagree on what materials to use, Williams laughs and says, “almost always, but we always end up in the place where we agree.”

Ultimately their vision is part of a dialogue between the project and the earth, as well as an ongoing conversation with the stakeholders.  “We want our buildings to grow from the earth to the extent that they can,” Williams says. “When you’re talking about stone, you need to be humble because it has been around for a very, very long time.”

Timeless Beauty: Chicago Landmark Restored to Its Natural Stone Glory

Exterior 1883

After the 1871 Great Chicago Fire, many homes made of wood were destroyed. When it came time to build new homes, laws were passed to prevent a similar disaster. Fireproof materials such as brick, marble, limestone, and terracotta tile became the preferred building materials since constructing buildings with wood was banned in the downtown area. 

Eight years after the fire, construction of the Nickerson House on Chicago’s near northside neighborhood began. The three-story, 24,000 square foot Italianate mansion was reported to be the largest and most extravagant private residence in Chicago at the time it was completed. The exterior façade is made of limestone and Berea sandstone from Ohio. Known as the “marble mansion,” the property is even more impressive inside. “The interior stonework consists of at least 17 different types of French, Italian, Belgium, and American marble as well as onyx and alabaster,” says Sally-Ann Felgenhauer, director of collections and exhibitions for The Richard H. Driehaus Museum. 

Exterior Pre-Restoration

Soon after it was built, the light-gray sandstone exterior would lose its luster due to environmental issues. “Over the years, the naturally light stonework blackened due to the build-up of soot and grime from industrial pollutants,” Felgenhauer says. As the exterior became dark and unsightly, the decorative stone elements also began to erode. 

The Nickerson House became The Richard H. Driehaus Museum when Richard H. Driehaus, a Chicago investment manager well known for his interests in preserving historic buildings, bought the home in 2003. According to a New York Times article, Driehaus purchased the home from the American College of Surgeons, a professional association that had owned it since the 1920s and soon afterward hired M. Kirby Talley Jr., an Amsterdam-based author and art historian, to oversee the restoration.

“My marching orders were to take it back to 1883,” Talley says in the New York Times article. “It’s remarkable to find a situation like this where you can honestly say that no expenses were denied to do the job the right way.”

In 2003, the same year Driehaus acquired the property, major restoration of the building began, including restoring the exterior façade.

Restoration of a Historical Landmark

“The Driehaus Museum as a Gilded Age mansion is an important piece of Chicago’s history and a window into the past that looks forward by exploring the interplay between historic and contemporary art that honors the legacy of Richard H. Driehaus,” Felgenhauer says.

Restoring the exterior required careful work by skilled teams. According to Felgenhauer, none of the stonework has been changed, but it has been restored. 

The sandstone and limestone used were both native materials to the Midwest. Berea sandstone, quarried in Ohio, was a common choice for buildings. Sandstone is a soft and porous material and while fireproof, would eventually absorb the soot billowing from the smoke from nearby coal plants. By the time Driehaus purchased the property, “those industrial pollutants had morphed into a kind of 100-year-old crust. In some places, that crust was 20 millimeters thick,” according to the Driehaus Museum blog post on why the Nickerson House used to be black.

“During the restoration, the Driehaus Museum contracted the Conservation of Sculpture & Objects Studios, Inc. (CSOS) to clean the façade using handheld lasers through a process called ablation,” Felgenhauer explains. “They removed 20,000 square feet of black crust from the stonework over a period of 18 months between 2004-2005. This was officially the first building to be cleaned in North America using this process.”

The reason lasers were used instead of more aggressive approaches such as micro-blasting was because the exterior was so soft that a harsher process would have resulted in worsening of the erosion and in some cases bleaching out the sandstone’s natural yellowish color. 

According to the Driehaus Museum website covering the natural stone exterior restoration project, the laser cleaned at a rate of approximately 2.5 square feet per hour. 

The website shares a bit more detail on the process of using the laser. “A beam of light from a handheld contraption is pointed at the building, and it breaks the molecular bond that had formed between the stone and pollutants,” according to Driehaus Museum. 

According to Felgenhauer, the CSOS team spent more than a year clearing 20,000 square feet of black crust and it was all done with small handheld instruments.

The building was added to the National Register of Historic Places in 1976 and designated a Chicago landmark on September 28, 1977. In 2008, the Commission on Chicago Landmarks awarded the Richard H. Driehaus Museum with the Chicago Landmark Award for Preservation Excellence, Felgenhauer adds.

Keeping Natural Stone Looking Great

Exterior Post-Restoration

While the restoration project was completed in 2004, the museum continues regular maintenance which includes restoration and conversation. “More recently, as part of the museum’s maintenance program, the building façade underwent tuckpointing,” says Felgenhauer.

It’s a testament to its longevity that with proper upkeep and maintenance, natural stone can withstand even the harshest elements and last for centuries.

How to Use Natural Stone to Create At Home Water Features

Being near water has a calming effect and research studies have shown that water features can positively contribute to our overall mental health and well-being. Incorporating natural stone water features at home can bring both beauty and tranquility into your space. 

Anne Roberts, president of Chicago based Anne Roberts Gardens Company, finds that people love the sound of water because it’s relaxing. Since not every home has a water feature, adding one is a way to make your home stand out.

Michael Zimber, founder of Santa Fe-based Stone Forest, often uses natural stone in his water feature designs. According to Zimber, many homeowners choose to add a water feature to their outdoor spaces for aesthetic reasons or because it goes well with other elements in their space. “Water features add a dramatic focal point in the garden space; a tapestry of sound, visuals, and texture that attracts birds and other wildlife (including the human variety),” Zimber says. Another benefit? Water features mask road noise quite effectively.

Why add a natural stone water feature

There are countless options for natural stone water features in landscape design, including fountains, basins, waterfalls, ponds, and pools. More elaborate designs include computerized water features synchronizing music to water and light animation, like what you might see in Las Vegas or the front of some hotel properties. 

Natural stone fountains will last for generations, according to Zimber. In addition to helping mask road noise, natural stone water features can become a focal point or help define a garden space.  

Contrary to what some people might think, a water feature doesn’t have to be large like a pool or big waterfall design. “Natural stone water features can be as big or small as you have space for,” Roberts says. Her company has installed smaller streams with recycling water systems, small foot ponds, and even large natural dry riverbeds for water that periodically overwhelms areas in one’s yard.

What to consider when installing a natural stone water feature

Natural stone water features can make a dramatic statement, whether as a focal point of a space or background statement. There are several things to take into consideration when choosing a water feature, including price and maintenance. Here are a few additional things to consider when choosing your water feature. 

  • The size of the reservoir. Both Roberts and Zimber remind clients that the final design needs to fit the desired space. 
  • Size and weight of the water feature. If a sizeable fountain is being considered, for example, how will it be installed? Will it require a dolly/ hand truck, forklift, or crane?
  • Incorporate plants. This will be geography dependent, but something to think about as you’re deciding the location of your water feature. In the southwest where Zimber is based, it’s all about drought tolerant species. “It’s nice to ‘layer’ different perennials around the water feature,” he says.
  • Let the light in. Adding lighting systems will bring some visual interest to your space during the night.
  • Consider short- and long-term maintenance. In addition to making sure pumps and other accessories are in working order, homeowners will want to add cleaning the reservoir to their calendar once a year, Zimber says. He also recommends using an algaecide that is bird and animal-friendly, along with a weekly dose of a chemical to fight hard water buildup.

Types of natural stone water features

Natural stone water features can be true works of art in an outdoor space and part of their appeal is they engage several of our senses. Not only can they provide a soothing backdrop from the movement of water over the stone, but they provide a striking visual with their textured designs. 

When choosing a water feature like a fountain or basin, you want one that will be built to last in your environment. “Granites and basalt can handle cold environments and will last for generations,” Zimber says. Some gravitate toward stunning marble and onyx fountains which may not hold up quite as well, but generally will withstand the life of the garden and homeowners, Zimber adds. 

In addition to the water feature, most pieces include rocks or smaller stones beneath the focal point to capture the movement of the water.

Zimber and his team design and carve natural stone fountains. Their designs range from traditional Japanese and Old World to natural or monolithic contemporary. Fountain shapes can be in a boulder shape, millstones, sphere, or vertical. They truly can be customized to your unique space, interests, and budget.

One of the most common mistakes Zimber sees with homeowners and water features is sub-standard installations. If you’re not planning to hire a professional to install your water fountain, Stone Forest has a blog post on creating a successful fountain installation that Zimber directs people to so they can do it themselves correctly. Another mistake Zimber sees is buying a cheap foundation made of concrete. Those, he says, tend to fall apart after a few seasons.

If the project is beyond your DIY capabilities, Roberts highly recommends hiring a firm with experience installing water features such as ponds as not every landscape has that expertise.

Once you install a natural stone water feature, you’ll be able to enjoy it for decades.

The Perfect Match: Digging Deep to Restore the Wyoming State Capitol

|

Just one highway leads to Rawlins, Wyoming, a small city 150 miles northwest of the state capital of Cheyenne. Rawlins straddles interstate route 80, but otherwise has drawn little attention to itself since its glory days in the 1800s, when it served as a freight and passenger stop on the Transcontinental Railroad. 

In the late nineteenth century, a quarry here produced sandstone for construction projects throughout the region. Rawlins sandstone glows in sunlight with a warm gray that lends a stately air to building exteriors, making it particularly attractive to designers of ornate government edifices. Overseeing the quarry’s production, owner Hans Larsen knew that this high-quality stone should be the fundamental material to grace the Wyoming territorial capitol building, for which construction began in the mid-1880s, several years before Wyoming received statehood. However, the architects had specified sandstone from Loveland, Colorado for the foundation and the capitol steps, with plans to bring more of this stone from Loveland to create the ornamented façade. 

Hearing of this insult to Wyoming quarries, Larsen stormed into Cheyenne, demanding that the local government use materials from its own resources rather than importing stone from another territory’s quarry. Government officials, no doubt taken aback by this fiery businessman, saw the wisdom in his point. Larsen won the contract, making Rawlins sandstone the material of choice for the capitol’s impressive exterior. Skilled stone masons created hundreds of detailed sculpted features by hand. Each column, corner, and cornice was a unique tribute to the sandstone’s quality and durability. The finished structure, including the towering rotunda, opened in 1888. 

Not even Wyoming sandstone can last forever, however, so some 130 years later, Wyoming’s infamously harsh winters had taken their toll on the original building, as well as the additions to Capitol Square constructed in 1890 and 1917. In 2013, the state began a massive $299 million renovation of the entire capitol complex, bringing top talent from across the region to Cheyenne to restore the grandeur of this splendid Renaissance Revival façade. The state determined that the restored capitol should look exactly as it did when the first crew completed it in 1888, so the team of architects, masons, and fabricators looked northwest to Rawlins once again for stone to match the building’s worn exterior. 

But Rawlins no longer had a working stone quarry. The quarry had closed in the 1920s, nearly 100 years before.

Unearthing the Stone

The land containing the former quarry now belonged to Overland Trail Cattle Company, a major ranching and cattle operation and a subsidiary of Anschutz Corp, a private equity company based in Denver, Colorado. 

“Eldon Strid, a local person, provided a tremendous amount of knowledge about where the quarry was and who the owners were,” said Jeff Callinan of J.E. Dunn Construction Company, the general contractor for the state capitol project. “The land had recently changed hands—they were about to put a wind farm on this land.”

J.E. Dunn tried to contact the owners, but when they received no response, they enlisted the help of the governor’s office of the State of Wyoming. Governor Matt Mead and his staff approached Anschutz and “managed to shake it loose,” Callinan said, striking a deal that allowed the state to take 253 tons of sandstone from the former quarry for a reasonable price, providing the state found its own people to bring out the stone. J.E. Dunn tackled this tall order and located a mobile quarry operator in South Dakota. 

“We’d never had to set up a mobile quarry before,” said Callinan. “Normally, we are in the business of going out to the quarry to select big blocks of stone. In this case, we had to learn about the front end and getting the stone extracted. It’s a logistical project to get the stone out of the earth and get it to the people who can create a piece to go into the building. This team knows how to go through that logistical challenge.” 

The governor’s office of the State of Wyoming helped in the access in the capitol’s former quarry source in Rawlins, WY, which had closed nearly 100 years before. 235 tons of sandstone were quarried and used in the restoration effort. Here, cuts are made in the sandstone where sections of block will be extracted using a wire saw. Photo courtesy State of Wyoming.

Setting up a mobile quarry came with its own package of obstacles, Callinan explained. “We had to build a road. We had to coordinate with the Department of Corrections because there was a prison nearby. Then the Fish and Wildlife Department identified that a golden eagle was nesting in the area.” Golden eagles are a protected species under the Bald and Golden Eagles Act of 1940, so the quarry team had to wait for a month to begin their work until the eaglets had fledged and the birds abandoned the nest. 

The effort to reopen the long-dormant quarry proved to be more than worthwhile, said Tom Van Etten, president of Galloy & Van Etten, Inc., an award-winning family-owned stone fabrication company in Chicago. Van Etten led the twelve-person team that turned the Rawlins sandstone into meticulously cut and sculpted replacement pieces for the Wyoming project. “It’s a perfect match,” he said. “They found not just the right quarry, but the right stone matching in color.” 

Choosing exactly the right cuts of sandstone—matching the color of each to the existing stonework in the capitol façade—became the full-time job of preservation architect Katie Butler of CSHQA, headquartered in Boise, ID. Butler and CSHQA principal John Maulin came into the state capitol project in 2015 at the request of HDR Architecture, Inc., the architect of record. “I visited the site in Wyoming almost every other week for three years and attended numerous trips to quarries and fabricators to select the stone, review samples, and ensure the processes were in compliance with the construction documents,” said Butler. 

The process began with the team comparing a series of seven Rawlins sandstone samples, ranging in color from gray to buff, to each building level and elevation of the three building periods. “After a day on a lift, three samples were consistently found to match the existing stone at all areas,” said Butler. “These three samples established the range of colors we would use to select blocks from the Rawlins quarry.” The team visited the quarry three times between October and November 2015 to determine if the 3’ x 3’ blocks were in the correct range for color and veining.

“It was quite the process,” said Butler. “At each site visit, we reviewed stone from different parts of the quarry—south pit, middle pit, and north pit. It was all the same type of sandstone but varied from each part of the quarry. It was tough trying to make sure that the underlying color and variation would be appropriate, especially with the building having been built in multiple phases.” After each visit, the team documented the process with photos and summarized it all in a field report. 

When stone became available from the Colorado quarry in Loveland for repairs of the stairs on the north and west side of the building, Butler and her team repeated this painstaking comparison until they found the right match for the existing steps. 

With this process completed, Butler and the rest of the team—Scott Evett from masonry contractor Mark 1 Restoration Company; Mike Ford, senior associate with stone restoration architect Wiss, Janney, Elstner Associates, Inc. (WJE); and representatives from J.E. Dunn, HDR, and the State of Wyoming met on site regularly to review mockups, trial repairs, and overall project progress. 

Enormous Scope

While the historians searched for exactly the right stone, Ford and the WJE team worked with Mark 1 Restoration to determine the scope of the required repairs. “It was about developing a repair approach that we thought was good and sound, but prioritized enough that we could do the repairs we felt were most important, deferring others,” said Ford. “We went on site, did an investigation, and provided options for repair.” 

Placing life safety above all other priorities, the WJE team discovered that the stone at the base of the building—the two courses quarried in Loveland—had deteriorated enough to raise concerns about its continued viability. A clear surface treatment had been applied to this stone in the 1990s, but it did not prevent damage from water and weather, and it “likely accelerated deterioration,” a report on the project noted. Many of the cornices and column capitals showed “severe delamination,” the document continued, also due primarily to water exposure. Some areas had been patched with mortar and stabilized with protective netting, applied years before to slow the progression of the inevitable—and to keep pieces of the façade from raining down on passersby.

When it came to the restoration of these decorative elements, Ford and his team presented the state with options. “Often people look at these projects and say, ‘I can’t do that,’ instead of ‘Yes, I can do it, and this is what it will look like,’” he said. “For example, if you have snow and it sits on cornices and ledges and it melts, it gets into the stone and it absorbs. Then it freezes, and it happens again and again—that’s called thermal cycling, or freeze/thaw. A lot of the distress we were seeing was at these projecting ledges. We said that we could do dutchman repairs to match the original, and could improve water management; however, another approach could include installation of a sheet metal flashing. This may address water management and be more cost effective, but it would have an aesthetic impact.”  

WJE installed a mockup of both the stone dutchman and flashing approach and showed the state. The state chose the dutchman approach. “That is fine; they were able to make a good decision with the mockups and an understanding of the benefits and drawbacks we presented,” said Ford. “It’s a historic building. You want to keep the historic character and integrity.” 

In all, a total of 1,135 individual pieces throughout the building’s exterior required repairs or replacement, using 3,160 cubic feet of stone. “We put the stone in a local yard until we shipped it to Galloy & Van Etten in Chicago,” said Callinan. “There were truckloads and truckloads and truckloads.”

As if the size and scope of the project were not complex enough, the original architect in the 1880s, Davis W. Gibbs, had designed just about every feature of the ornate European-inspired façade to be unique.

“As a masonry restoration fabricator, Mark 1 created a shop drawing for each additional piece,” said Callinan. This shop ticket included the type of stone, its dimensions, the dutchman repair styles required, the number of the actual block of stone from which this piece would be cut, elevation drawings, and tooling requirements. “These would be approved, and it would go into fabrication. A lot of times they oversize them a little bit, so onsite they can tool it a little bit to get a perfect fit. Some have similar profiles and textures, but each piece was fabricated for a specific place and purpose.”  

The masonry team worked to develop standardized details for categories of stone profiles—so all the cornice ledges, for example, had the same basic shape and required the same kinds of onsite work once they arrived at the job site. “Every stone on the building was assigned a number, so you could see all of these on the elevations,” said Butler. Tom and Susan Van Etten led the effort at their Chicago facility to fabricate the profile of each element, roughing in the shape and preparing it for the decorative carving to be done by hand in Cheyenne. 

On site, masons from Mark 1 installed the dutchmen that had been fabricated in Chicago at Galloy & Van Etten with planers, pneumatic chisels, combing tools and other shaping devices to create exact replicas of the original detail for each column and cornice. Portions of the building were hand-finished on site—the rock face of the base stone, for example, using a small pitching tool to remove bits of material at a time.  

Butler totaled up the various kinds of repairs the project required: four different kinds of joints, eight different resurfacing techniques, 33 kinds of dutchmen, and two types of surface treatments. “WJE and CSHQA worked as a team,” she said. “WJE reviewed each repair for structural integrity and watertightness, while CSHQA would take the lead on the aesthetic appearance. There were only a couple of occasions where we had to change something because the stone wasn’t a good match.” 

Every facet of the stone restoration required meticulous work by hand using small tools. Photo courtesy Wiss, Janney, Elstner Associates, Inc.

The Reopening

Four years of overhaul—the complex’s first major renovation since 1917—resulted in a state capitol worthy of the accolades it has received. The stonework received the 2021 Grande Pinnacle Award from the Natural Stone Institute, while awards for the total project streamed in from many trade organizations: the American Public Works Association, Building Design and Construction magazine, the American Council of Engineering Companies of Colorado, the Construction Management Association of America, and Engineering-News Record Mountain States.    

“A project like this takes extraordinary skill, but it takes a team that knows who the right players are to accomplish it,” said Callinan. “It was extremely helpful to bring the right artisans to the table. The stone masons who were carving the stone onsite were the same people who worked with us on two other state capitol projects.”

State capitol restoration stands in a class of its own, said Butler, making this her favorite kind of work. “There are only fifty state capitols,” she pointed out, “so it’s a really special building type. It’s fun to see how things can be put back together and preserved without it looking like it was ever touched.”

Connecting with Natural Stone

Andreas and Naomi Kunert, co-founders of Ancient Art of Stone, know they don’t easily fit into one category. Together they create one-of-a-kind art installations using natural stone, crystals, and bronze. 

“We’re not stonemasons, we’re not necessarily sculptors, and we’re not mosaicists. Yet we use all of their skill sets,” Andreas says. 

Andreas and Naomi are artists, first and foremost. It’s not unusual for their art pieces to be 25’ tall. An upcoming project will include a 900-foot mosaic wall, with 20 feet surrounding it and large doorways with 350 ton standing stones that one can walk through. 

“From a megalithic point of view, it’s very moving and very to the point,” Andreas adds. 

Listening to clients and to the stone

Their clients don’t always know what they’re looking for at first. While this approach can be challenging for some people, for artists like Naomi and Andreas, it’s an opportunity to develop a design that is 100% personalized for their clients.

Their most recent client approached them to design a piece to add to their home, which was on 40 acres of land. They were referred by their landscape architect to create a focal point at a roundabout leading up to their home down the long driveway. When they first met with the client, it was clear the client didn’t have a design in mind. In fact, the client had no idea what to suggest; no idea of height, scale, or colors. So Naomi and Andreas came back to their studio and leaned into their process by channeling who they met and hearing what was shared.

“What did they tell us about their life? What was important to them?” Naomi asks. 

The discussion moved from what they felt to what might be important. Family and community seemed important. What Andreas noticed from their initial meeting was the couple was the nucleus of a larger family and they cared about the people in their community. 

“We developed this design of a taller stone standing together, which represents them, husband and wife, and then a sphere, emerging from the two stones, which represents this family and this caring community,” Andreas says.  

When presented with the design, the client loved it without any edits. 

Choosing the right stones

Years of experience have taught Naomi and Andreas what’s possible and working with talented engineers has allowed them to create award-worthy projects for their residential and commercial clients. 

The design is one part of the equation. Another is finding the right stones for each project. Those stones come from a variety of places. While they source some stones in their travels, some come directly from the client. In one instance, Naomi recalls a client whose father collected arrowheads that he found on his land. Those pieces were incorporated into a fireplace design as a way to honor their father. Those types of scenarios aren’t uncommon. 

“I think it does depend also on the client, and what their needs are as part of that listening and as part of my interest in health and healing,” Naomi says. “So through that, listening and getting to know them, there are certain stones that will kind of come more forward in my mind.”

Finding connections

Connections to the ancient art of natural stone used in projects are important to Andreas and Naomi. When it comes to the philosophy of their work, Naomi says it’s wise to look at the ancient ways natural stone has been part of all of creation. For Andreas, whatever they build, they build it with longevity in mind and what they create will outlast our generation and generations to come. 

Commissioned designs are completed in their studio in Cowichan Valley on Vancouver Island and then shipped to the client’s location. It’s not uncommon for a client to become emotionally moved once they see a piece in real life. That’s when Naomi knows the spirit of the stone is speaking to them. Once they’re in front of the artwork, and allow the piece to speak to them, it moves them in a way that cannot be explained.

One project, two minds

Clients love getting the opportunity to work with both Andreas and Naomi. “I think that’s very unique to us, working together as a couple,” Andreas says. “Naomi has an amazing ability to tune into people. When we meet a new client, she can really zero in on who they are and ask them things that stop them in their tracks, makes them think. And ultimately, when the artwork is produced, and it happens every time, they’re very moved; that this is very specific to them. And this pretty much Naomi initially tuning into them. And it is the two of us, that’s really important.”

Using Locally Sourced Limestone to Add Structure and Strength to Historic Preservation Projects

|

Julia Manglitz, AIA, LEED AP, APT RP, has worked on several building types throughout her career: county courthouses, state capitols and office buildings, university campus halls and community centers. What makes each of these public buildings unique is they’re all landmarks in their communities. Another thing each of them has in common? Almost all feature locally or regionally-sourced natural stone.

Manglitz began her work in Kansas, where limestone is plentiful. As a result, most of the older heritage and iconic buildings showcase local limestone. The featured projects were completed during her tenure as an associate principal of historic preservation at TreanorHL. She recently transitioned to senior architect with Quinn Evans.

Manglitz assessed sixty stone buildings on the Kansas State University campus in the summer of 2019. The buildings ranged in age from 20 to 143 years old; the study identified life-safety and water infiltration issues to help the University prioritize and plan façade repairs.

Stone is one of the original regional materials

As an architect focused on historic preservation, Manglitz works with natural stone often. Stone has been used often throughout history for its durability and because it is fireproof. Manglitz notes that natural stone structures were also lower maintenance than wooden structures that required frequent repainting.  

As westward expansion began and immigrants from Germany, Sweden, Italy, England, and Ireland settled in or passed through states like Kansas, many brought with them a history of stonework and masonry. An abundance of usable stone in relatively modest sizes available in quarries throughout the Midwest made it easy to source and use.  

“There were various times of groups moving through. Some settled, some kept moving, but there were generally people around who understood what good material looks like, how to get it out of the ground, and how to get it shaped and put into buildings,” Manglitz says.

The case for regional natural stone

Kansas is known for its limestone. Manglitz notes that one of the most well-known stones is Cottonwood limestone, a light gray-to-cream-colored fine-grained limestone. Cottonwood is the main facing material for many buildings on the University of Kansas and Kansas State University campuses as well as much of the Kansas State Capitol.

Another local stone is Silverdale, a creamy limestone with gold color tones often used in split face veneer stone applications and cut limestone applications due to its tight grain and lack of holes or pits. 

“One of the more interesting stones that we run into a lot at Kansas State University is something called Neva, which is a slightly higher density limestone,” Manglitz adds. “It’s good for rough ashlar work and rock faced finishes.”

Neva is often mixed with Cottonwood, which is softer and can take a tooled finish.

The Kansas Statehouse exterior masonry restoration, completed in 2011, required over 7,000 dutchman repairs varying in size from a few pounds to several thousand. The façade features four types of limestone and seven granite, dating from the original construction to subsequent repairs. The project received a 2018 Tucker Design Award.

Historic preservation and natural stone

While limestone is readily available throughout the Midwest, Manglitz notes sourcing can still be challenging for historic preservation projects, since blocks are not always actively quarried in the same size that were originally used on a building. 

“Trying to get material in the size that you would like to get it can be a pretty important part of sourcing the stone,” she explains. “When we’re working in preservation, that’s really dictated by the existing building. When we have to go out looking for substitute materials, or substitute stones, it does get really challenging.”

In some cases, Manglitz is trying to match the original color on a building. Other times, she’s looking for a stone that can work with a particular finish. “A lot of the buildings that I work on have some sort of tooled finish to them or they have carvings incorporated, and trying to make sure that you can accurately replicate and get the same feel for it is important,” she says.

Victory Eagle connects with University of Kansas campus

Manglitz works to recommend stone based on everything from price to aesthetics. She and her team were called upon to work on a 1929 “Victory Eagle” statue in honor of Douglas County residents who lost their lives fighting in World War I. The bronze Victory Eagle monument features a mother eagle with her wings spread wide, defending her eaglets in a nest. 

The statue had seen better days after being stolen and thrown in a ditch before being rescued in the early 1980s. A new base needed to be designed before it could be relocated to Memorial Drive with other war memorials. The client initially wanted a base that wasn’t a native Kansas stone, but Manglitz recommended other stones that would be a more appropriate fit. 

Victory Eagle: The 1929 bronze sculpture, Victory Eagle, moved to a new home along Memorial Drive at the University of Kansas in 2019. The stone pedestal follows the pattern historically recommended by the Victory Highway Association, which organized the memorials in 1921 to commemorate the loss of life in World War 1. Silverdale limestone, quarried in southern Kansas, and Mountain Green granite from Coldspring form the pedestal. Photo credit Julia Mathias Manglitz.

She began by recommending granite for the first two courses. “Granite is going to hold up a lot better; it’s not going soak up de-icing salts that are likely to be used on the sidewalks and it will handle that installation much better than limestone,” she shared, adding that the dark green granite from Coldspring goes well with the overall landscape, since it sits on a site looking down into a forested valley.

The main shaft is Silverdale limestone from Kansas. “Silverdale has a little bit of a warmer color and it tends to go better with the existing architecture,” she says, again emphasizing the importance of regional stone used on other buildings throughout the area. “The more locally sourced stones historically used on the campus have a slightly warmer tone to them.”

Manglitz sees many benefits to choosing locally sourced stone over manmade materials like precast concrete in her work. She points to the lower embodied energy inherent in natural stone when compared to precast concrete as a major factor. “Precast you can do anywhere,” she says. “When you’re using a local stone product, you’re linking yourself to the history of construction within your particular region. It’s partly about place-making. It’s partly about the environment. And it’s partly thinking about durability for the next generation.”

There aren’t many nearly freestanding buildings in the middle of New York City, but 2 Bryant Park is located on a unique site.

“The building, which is not the tallest building in the area, happens to be open on three sides,” Dan Shannon, architect and managing partner of MdeAS, an architectural company that specializes in commercial office building development, institutional, and multifamily residential developments primarily in the New York City and metropolitan area.

To give some perspective of 2 Bryant Park’s location, it is surrounded by Bryant Park to the south and the Avenue of the Americas on the west.  A public plaza is located on the north side.

The existing building cut the two parks off from one another and had a small, poorly positioned lobby. To better connect these spaces, the central column bay and structural slab were removed from the first and second floor, creating a double-height lobby concourse linking the two parks and pulling pedestrians from one space to the other. 

Shannon and his team wanted to take advantage of the unique footprint of the building and connect the park to the plaza visually. Choosing the right natural stone would prove to be a pivotal decision. They decided to create a two-story high entry lobby passage through the building and elevate that open space using Thassos White marble from Greece along the primary and surrounding walls.

Why Use Natural Stone? 

Shannon is drawn to using natural stone in his projects because natural stone represents quality, durability, tradition, and elegance. He finds we’re also fundamentally moved by natural materials like wood or stone.

“It’s part of our psyche. It’s part of where we came from. It’s part of where we’re going,” Shannon explains. “When people respond in a positive way to an architectural space, it generally has a lot to do with the use of natural materials.”

When he was working on 2 Bryant Park, Shannon was clear in his vision for the spacious lobby and entryway. Those who live, work, and visit New York City are often in a hurry. They need to get from one place to the other and don’t have time to notice the beauty in plain sight. He wanted people who walked into that space to stop—to notice and appreciate the natural stone. He wanted them to respond to it.   

The Different Facets of Thassos White Marble 

Thassos White marble offers different appearances depending on how it’s treated, and that’s one of the reasons he really wanted to use it in 2 Bryant Park.

The predominant walls were made of honed slabs and nylon brushed. “What the nylon brushing did was give it a very nice matte finish,” Shannon explains, “but it also unified the material.”

Shannon reminds us that all natural stone carries some blemishes because it’s a product from nature and not manmade. Through experimentation with their partner in Italy, Roberto Canali from Euromarble, they were able to cover or eliminate some of the blemishes through nylon brushing.

Nylon brushing is also commonly referred to as a leathered finish. “It feels like leather, it’s got a little bit of rippling, but it’s not as rough as thermal,” Shannon adds. “It came into prominence about five to ten years ago and they’re doing it mostly on marbles because it gives the marble a kind of old world look to it. It looks like it’s worn. It gives it a richness.”

Whereas part of the wall features a nearly pure-white sleek matte finish, he and the team wanted contrast for the sides, so they considered black Italian slate.

“Slate has that beautiful cleft finish,” Shannon says. “When it gets pressure along that grain, it cleaves and creates that nice texture cleft surface, which looks like you you’re looking at the topography of the world.”

While the design team and ownership really liked that look, it was decided that the black Italian slate was too much contrast for this room. “We all wanted a more subtle reading.”

This is where the versatility of Thassos White marble came back into play. Shannon went back to Canali to experiment with a different technique on the stone.

“We took large, thick pieces of the Thassos and put them into this hydraulic machine which had a blade on it, which puts pressure along the grain, on top of it, and it shears the marble,” Shannon explains. “What we found was within reason, with a certain size, with a certain amount of pressure, that we could get a positive result in terms of what we were looking for in the appearance.”

The appearance they were going for was that rougher quarry face when you’ve knocked out the blocks.

To achieve the look was the result of a process that involved finding the right size panels that would give them the kind of contours they wanted. “The bigger the panel, the more profile it was, and we couldn’t control it,” he notes. Finding the right size meant they could control the process better by placing the stone panels on wheeled carts so they could move them around. This allowed them to see how they each looked next to each other and get them closer to looking like they naturally belong to each other.

This process also allowed them to work on the panels by hand since some needed handwork to knock down some of the profile. “You may find a perfect piece but it had one bad part,” Shannon says. In that case, someone on Canali’s team would hit it with the chisel and be able to smooth out some of the imperfections or profiles that didn’t work with the adjacent material.

Natural Light Reflections on the Marble 

One of the things Shannon is most proud is how well the natural stone looks on the walls and how the impressive entryway connects to one of New York City’s popular green public spaces.

“It’s kind of like this kaleidoscope connecting these two worlds,” he says. “It really does happen during the day. Sometimes you get the green reflection of the trees that tint the stone because it’s white, and I think that’s just magical. It really is that contrast and the simplicity of it. That is fantastic, you know, just really unique.”


Shannon’s initial vision for the lobby of 2 Bryant Park was for people who walked into that space to stop, to notice and respond to the natural stone. There is no doubt that 2 Bryant Park has carved a name for itself thanks to Shannon and his team who were willing to experiment with what natural stone could do.
