According to the Washington Business Journal, Douglas Development has purchased 736 and 740 Sixth Street NW in Chinatown and plans to redevelop. These buildings host office tenants and the Kanlaya, Burma and Urfa Tomato Kebab restaurants. The redevelopment would reskin the buildings and add a fourth floor.
The rendering below shows what the mixed-use redevelopment would look like. A little bland and I will sorely miss the neon signage the restaurants had which offered the block some character.
