The Building

Blocks from the White House, 1801K represents an unrivaled opportunity in the heart of DC’s Golden Triangle.

The landmark building offers one of the largest, most efficient floor plates in Washington, and the freestanding nature of the building, coupled with its column-free perimeter, provides sweeping views of Washington via continuous floor to ceiling windows along K Street, 18th Street and L Street.

Designed by Skidmore, Owings and Merrill, the building offers 42,300 SF floorplates, virtually column-free interiors and floor-to-ceiling windows.  This design allows for the utmost flexibility in layout and ample natural light through more than 1,000 feet of perimeter glass and 210 windows. Already home to such prestigious names as KPMG, NCARB and Jones Lang LaSalle, this high-visibility corner is ideal for tenants seeking a well-designed and well-located space.
