Specialty Hospital of Washington at 8th and Constitution Avenue NE is a weird one: A big office building in the middle of a residential neighborhood, with pretty much nothing going on during the weekends. While the northern half of the building is a nursing facility with 60 beds, the southern half has been lightly used as offices for hospital staff and the landlord.

That piece will be a lot more intensively used, if a plan by IBG Partners works out. The developer has secured a 75-year lease on the southern chunk, and plans to convert it into as many as 140 apartments, while the hospital part of the building goes about its business as before.

Their first step is historic preservation review, since a piece of the original 1928 building is a contributing part of the Capitol Hill historic district. According to IBG’s Scott Fuller, the old part will be restored to its original condition, with all the ugly 1970s wrapping torn down. A 1950s addition will get bay windows going up three stories. The whole project is contained within the footprint of the existing building, with the exception of a small addition that won’t be visible from the street and won’t add overall square footage. Finally, they’ll be adding parking underneath the building, with the number of spaces depending on the number of apartments they’re able to fit inside (the floorplans below represent the highest-density case).

There’s a concept presentation for the Historic Preservation Review Board after the jump.
