The Architectural Record has a nice article on Fort Totten Square with a few renderings (click link to see photos). The architect, Hickok Cole, noted how the topography of the land was favorable to incorporating underground parking. From the very beginning of the project, the architects stated they wanted to build something that was more modern for the neighborhood. They accomplish that with several types of material on the Riggs Street facade, but they incorporate more brick veneer for the apartments on the 3rd Street side to blend in with the more residential feel of that street. They also use more brick on the retail space at the corner of Chillum Place.
The developers noted they want to attract young people who want access to the city without paying downtown prices. Judging from the renderings, the residents will be enjoy two beautiful courtyards with a pool and other amenities. At the Fort Totten Square community meeting, someone did ask about neighborhood access to the pool. The answer is to become friends one of the residents there.
On a personal note, I have never been crazy about the amount of blue branding incorporated into the design. However, it will be a massive structure, so once we see it at scale, perhaps it will not seem as overwhelming.
