Upon entering the lobby of the Dewey Ballantine law offices, located inside of the Carroll Square building in the heart of downtown Washington, DC, guests are exposed to a simply designed lobby with visually stunning features. Throughout the project, our Company worked diligently with Studios Architects to choose a color scheme that would achieve a clean, welcoming, and visually stunning appearance to visitors of the building.
The most significant and most intriguing feature of the lobby is the Noir St. Laurent Feature wall. This wall, which stands 18’ x 24’. The panels are enormous, roughly 9’ long x 4’ wide, and they were fabricated and installed in a diamond book match pattern, using only 1/16” joints. The challenge here was to find a block that would allow for a beautiful book match pattern and include the highest amount of red veining available in Noir St. Laurent. To complete the wall, the block was specially picked in Italy, with the help of the quarrier, the owner, the architect, and our Company’s President/Owner. Due to the large piece sizes, there was virtually no waste, so the block and the resulting slabs had to be perfect in color and vein character.
Located directly in front of the feature wall stands the elliptical staircase made of Corinthian Beige Mable. What makes this staircase so unique is that each cubic stair tread is individually supported. Due to the design of the geometry, each tread is a separate piece size and configuration. The landing is also one solid 4” thick panel roughly 8’x6’. To accomplish such a unique design, our team and the Steel contractor worked hand in hand to coordinate each element of the project. The outer part of the cubic tread is cantilevered beyond the steel support system and is integrated with the baluster system. The railing posts penetrate each stair tread, and a load of weight is shifted to steel brackets located on the underside of each tread. The exceptional craftsmanship of this staircase allows for the stairs to look as though they are floating in the air. This precise fabrication was achieved through diligence and cooperation from the steel contractor, the general contractor, and our team. At the bottom of the elliptical stairs sits a visually stunning raised plinth. This plinth, constructed of Noir St. Laurent, carries the same radii as the elliptical staircase.
Corinthian Beige marble was also used for the paving within the Dewey Ballantine lobby, and at the reception desk. A total of approximately 4500 square feet of Corinthian Beige marble was used to complete this lobby. Winner 2007 MIA Award of merit for Interior Stone.
