Architectural Stone Projects


We are very pleased to be producing over 14 truckloads of Grayson Slate for the complete slate roof replacement of The Dakota in New York City. Perhaps the most famous apartment building in the world, this much beloved structure was designed by Henry Janeway Hardenbergh and its construction was completed in 1884. Work on the roof replacement began in the spring of 2015 and will continue throughout 2017.
We are a proud supplier of the Grafton Cloud White Marble used at the iconic World Trade Center (WTC) Transportation Hub at Ground Zero in New York City. Designed by internationally acclaimed architect Santiago Calatrava, this train station serves 250,000 PATH daily commuters, the NYC Subway and millions of annual visitors from around the world. The sculpture-like centerpiece of the complex, named the WTC Oculus, symbolizes freedom and is a great source of pride for many Americans. Grafton Cloud Marble was specified as the signature white stone for the WTC Oculus floors and stairs after an intensive 5 year stone and quarry selection process. Over 350,000 square feet of honed finish Grafton Cloud White Marble was used for the floors, walls, stairs and benches of this graceful structure.
We are proud of our participation in the new Museum of Modern Art (MoMA) in New York designed by Taniguchi and Associates. We quarried and fabricated approximately 40,000 square feet of honed finish Vermont Unfading Green Slate featured throughout the building. We also supplied Janegrey Sandstone and Grafton Marble for the Museum.
We recently finished producing one of the larger slate roofing projects in the USA. It was about 1,800 squares (50 truckloads) of random width, mixed color Vermont slates for the new Yale University Residential Colleges designed by Robert A.M. Stern Architects. Of the total, about 900 squares was graduated lengths and thicknesses...24" lengths x 1" thick down to 12" lengths x 1/4" thick. We blended all 4 colors on each pallet to assist the roofing contractors.
