The program and design of MDX Flats follows the Capitol Gateway (CG) Overlay and its approvals processes. The CG-Zone, for projects with views in proximity to the U.S. Capitol, is intended to permit medium-to-high-density mixed-use developments with a balance of uses that would improve the quality of life and environment for residents and businesses. The plan encourages pedestrian-oriented streets with active ground floor uses. The resulting MDX Flats, located in SW Washington, is a two-phase development: Phase I is a 10-story affordable housing project with 78 units, and the 10-story Phase 2 contains 101 units, all affordable. Upper levels are articulated in bays that break down the scale, and the first floor provides features such as seating, which cater to the pedestrian experience.
