Just walking by this building today and again wondered what the hell is it? It’s at the intersection of 21st and New Hampshire with Ward Place off to the side, next to the Grillfish restaurant. It looks like an apt building, but on closer inspection, the front doors are practically boarded up, with no door knobs. There is no name or address on the building, yet all the windows have matching curtains and there were lights on in what appeared to be a stairwell. Is this another of DC’s “mystery” buildings?
