An existing single-family two-story plus cellar townhouse in the Greater U Street Historic District is rehabilitated and reconfigured into two residential units at 2,000 square feet and 1,600 square feet. A new third floor was constructed with a provate roof deck and a new addition was built off the rear façade from the cellar to the third floor. Congratulations to our client, Prime Investment Group, LLC and contractor, Harbor Builders.
