400 M Street

400 M Street is part of the revitalization of the Capper Carrollsburg neighborhood in Southeast DC. Funded in part by a HUD HOPE VI grant, the total neighborhood revitalization replaces 707 public housing units in isolated barracks style apartments with a mixed-income, mixed-use community founded on the best of Washington's traditions. Replacement public housing units include 162  senior rental units and 132 units of work force housing in two separate structures. Modest public spaces including a small clinic, management offices and meeting rooms are located in both buildings.

400 M is clothed in a more modern architectural language that relates to the character of M Street. This work force housing building is made up of 132 one bedroom apartments for individuals and families earning below 120% of area median income (AMI). Both the work force housing and the senior housing buildings were approved as part of a Consolidated Planned Unit Development, the largest of its kind at the time. This allowed for approval of the building design by the Zoning Commission simultaneous with the zoning approvals, eliminating the need for separate approvals and timelines.
