According to Lydia DePillis of the Washington City Paper’s Housing Complex column, Douglas Development has submitted a proposal to the Historic Preservation Review Board (HPRB) for design approval of a massive office building on the north side of the 600 Block of New York Avenue NW.
DePillis summarized the plan as:
The proposed development, designed by Shalom Baranes and shooting for LEED Silver, is 380,000 square feet of top-of-the-line office space. Most of the 32,000 square feet of ground-floor retail will be in the site’s old brick buildings, which will be consolidated on 7th Street (by the time they finish the project across the street, Douglas will be experts in moving buildings). In order to not build on top of them, they’re asking for permission to transfer density towards the east end of the site, which would be built up to 130 feet. One side would have wavy fins with rooftop gardens.
