Back in January, we heard that Douglas Development had finally found a way to move forward with two big parcels in Mt. Vernon Square currently filled with little, unimpressive buildings. The Association of American Medical Colleges took the whole block at 7th and K Street NW, and now, designs are working their way through the approvals process. I think the triangular stack with a huge elevated lobby and retail on the ground floor is pretty striking, especially when you consider that Douglas will be moving several historic structures across the street to make way for it.
