1625 Mass

Washington, D.C.

1625 Mass is a 114,000-square-foot office-to-residential conversion in Dupont Circle, Washington, D.C. set to open in 2026.  

The project’s interior design draws inspiration from the building’s heritage as the former Air Line Pilots Association headquarters, and the golden age of aviation. 

The reimagined building will provide 157 modern residential units, thoughtful and colorfully designed amenity spaces and a welcoming, reimagined streetscape to Massachusetts Avenue.
