That Park Potomac project is really nice... you can see it from 270 at Montrose Road.
My only gripe is that the streets feel a little odd... the proportion is just slightly too wide. The streets should be narrower. They have that weird swath of greenspace alongside them, but they're trying to evoke an intense urban environment where such parcels would never exist naturally.
The architecture itself is beautiful, but the streetscape just feels a bit odd.
The Thompson Hall project is ruined by the awful 2-dimensional windows and the terrible glass entry doors (what significant Georgian/Colonial/Neoclassical building has glass entry doors?)
The brickwork is fantastic though, and so is the slate roof, the moldings, and the gutter detail.
