The Foundry: Converting Office Buildings to Residential

Alexandria, VA

Converting office buildings to residential is no easy task, but with the right team it can be done successfully. This adaptive reuse project transformed a former government office building into The Foundry, a 16-story, 520-unit luxury multifamily community.  The residential facility incorporates 716,000 GSF of residential, 25,000 SF of retail and parking into the existing structure. The project provides an amenity-rich environment for residents. In addition to popular amenities such as a three-level gym, outdoor pool deck and an entertaining area, the building offers unique amenity spaces including a gaming area with a sports bar, pet run and spa, and an offering of workshop areas providing residents a space outside of their own to collaborate and create. The building is designed to achieve LEED certification.

The Foundry’s innovative building design has earned it a 2021 ENR Mid-Atlantic Best Projects Award of Merit in Renovation/Restoration and the 2020 NAIOP North Virginia Award for Best Building, Adaptive Re-Use.

The Foundry was completed in March 2020 and sold by Perseus TDC, Four Points and ELC Associations to Timberline Real Estate Ventures in December 2021.
