Robert C. Weaver (HUD) Federal Building

Washington, DC

Designed in the brutalist style for which Marcel Breuer is known, the Robert C. Weaver Federal Building is a ten-story administrative building employing precast and poured-in-place concrete as a structural as well as aesthetic material. In this regard, the HUD Building influenced the architecture of federal buildings for many years. The curvilinear “X” plan of the building results in expanses of windows on the main façades and blank end walls with projecting stair towers. The main façades of the building utilize pre-cast concrete at the exterior and the end walls are clad in black granite.
