The Architect of the Capitol, J. George Stewart, with the approval of the House Office Building Commission, selected the firm of Harbeson, Hough, Livingston & Larson of Philadelphia to design a stripped-down classical building in architectural harmony with other Capitol Hill structures. However, while the interior design of the other House Office Buildings retains decor one would expect to see in House Office Buildings (with cherry wood paneling, brass railings, and marble floors), the Rayburn building possesses design style parallel to that of the 1960s, with chrome push bars, clocks, and elevators, and space-age fluorescent lighting fixtures.
