This project entailed the renovation and revitalization of a Beaux-Arts style building in Mount Vernon Square. Work included preserving the historic facades, reinstating the interior’s original footprint, and restoring early 20th-century detailing.

The interior preservation strategy relied on identifying hidden historic chases, shafts, and vertical pathways to invisibly add new building systems and lighting while carefully integrating contemporary features. Exterior restoration work included cleaning the Vermont marble, removing and replacing deteriorated marble elements, and retrofitting the original wood windows with new energy-efficient glazing. The grand entry plaza on K Street was revitalized and resloped to provide full accessibility.
