Ariel Rios Federal Building

William Adams Delano and Chester Holmes Aldrich
Washington, DC

Located in the Federal Triangle in Washington, the building that was previously the U.S. Postal Service department is now the headquarters of the U.S. Environmental Protection Agency. Inspired by the Place Vendôme in Paris, the neoclassical building consists of two huge back to back, semicircular units with side wings. The curve of the building was to be mirrored by a similarly curved facade built across 12th Street.
