Robert C. Weaver Federal Building

The Robert C. Weaver Federal Building features a distinctive X-shaped design with four curving arms that maximize natural light throughout its ten floors.

The building opened in 1968 as headquarters for the Department of Housing and Urban Development, with President Lyndon B. Johnson attending the dedication ceremony.

The structure represents a significant example of Brutalist architecture in Washington, designed by Marcel Breuer with Herbert Beckhard and Nolen-Swinburne Associates.

Located at 451 Seventh Street SW, the building contains 700,000 square feet of office space and maintains restricted access for government personnel.

The federal building was completed under budget at 26 million dollars, three million less than the initial congressional appropriation of 29 million dollars.
