Located at 1000 Independence Avenue SW in Washington, D.C., the James V. Forrestal Building is a monumental low-rise Brutalist office complex designed by Curtis and Davis and completed in 1969. Originally constructed between 1965 and 1969 as Federal Office Building 5 to house United States Armed Forces personnel, it earned the nickname "Little Pentagon" before being renamed after James Forrestal, the first U.S. defense secretary. The structure encompasses three connected buildings—a Southern Building with eight above-ground floors, a Northern Building with four, and a Western Building with two—linked by two underground levels of office space. At 1.68 million square feet, it is distinguished by the North Building's dramatic elevation on 35-foot-high pilotis, which provide access to L'Enfant Plaza below. The building became headquarters of the United States Department of Energy following that agency's establishment in 1977.
