600 Massachusetts Avenue, NW

Located adjacent to the Washington Convention Center and close to Chinatown, SK&A recently completed structural design services for this new 12-story, concrete-framed Class “A” commercial office building.  Currently under construction, the structure includes 401,000 gsf of above-grade space, plus an additional 44,000 gsf of space on a below-grade concourse.  Parking is provided on three below-grade levels and totals approximately 132,500 gsf.  The project also required the relocation and restoration of two historic townhouses as additional office space. 

The building’s exterior facade incorporates natural stone, brick, and metal paneling along the glass curtain wall system.  Perimeter columns are spaced 30 feet apart for maximum openness and space.  Additional features include a light-filled lobby with stone flooring, wood and stone walls, and a water feature; floor plates with slab-to-slab heights of at least 11 feet; private balconies on five floors; and a rooftop terrace with an outdoor conference area.
