The 10-story office building in Washington, D.C. was owned by the federal government of the United States and served as the headquarters of the United States Department of Housing and Urban Development. The design resembles that of a giant capital letter "X" with an elongated spine and four bilateral, symmetrical, curving arms. The curvilinear shape allows the maximum amount of natural light to reach the maximum number of offices. A typical feature of Breuer are the deep-set windows in rectilinear shapes. The building was the first Breuer-designed structure in the United States to use a precast concrete façade.

Special thanks to Paul Severance for the hint!

On 2 April 2026, the U.S. Department of Housing and Urban Development (HUD) officially relocated its offices from the iconic Breuer-designed Robert C. Weaver Building to a former office building of the National Science Foundation in Alexandria, Virginia. This is part of a broader plan by the General Services Administration under the Trump administration to sell off a great number of Brutalist buildings in Washington D.C. that house various government agencies (another very important example of a loss is the remarkable J. Edgar Hoover FBI Building). These examples of Brutalist architecture were the brainchild of President Kennedy, designed to promote contemporary design in federal buildings—as an expression of modern American thinking rather than replicating historical styles.

What will happen to the Brutalist Breuer building remains uncertain. The building must be considered at risk of demolition and redevelopment (last updated on April 15, 2026).
