The Cannon House Office Building, often called the "Old House Office Building," completed in 1908, is the oldest congressional office building as well as a significant example of the Beaux-Arts style of architecture. It occupies a site south of the United States Capitol bounded by Independence Avenue, First Street, New Jersey Avenue, and C Street S.E. In 1962 the building was named for former Speaker of the United States House of Representatives Joseph Gurney Cannon. History The first congressional office buildings were constructed immediately after the turn of the 20th century to relieve overcrowding in the United States Capitol. Previously, members who wanted office space had to rent quarters or borrow space in committee rooms. In March 1901 Congress authorized Architect of the Capitol Edward Clark to draw plans for fireproof office buildings for both the House and Senate adjacent to the Capitol grounds. In March 1903 the acquisition of sites and construction of the buildings were authorized. In April 1904, the prominent New York City architectural firm of Carrère and Hastings was retained. Thomas Hastings took charge of the House Office Building project, while John Carrère oversaw the construction of an almost identical office building (now named the Russell Senate Office Building) for the United States Senate. Their Beaux Arts designs were restrained complements to the Capitol. The Cannon Building was occupied during the 60th Congress in December 1907. By 1913, however, the House had outgrown the available office space, and fifty-one rooms were added to the original structure by raising the roof and constructing a fifth floor that is visible only from the enclosed court and otherwise obscured on the building's public face. Originally there were 397 offices and fourteen committee rooms in the Cannon Building; the 1932 remodeling resulted in 85 two- or three-room suites, 10 single rooms, and 23 committee rooms. During the late 1960s, the House Beauty Shop, a salon which catered to Congresspersons, their spouses, and employees, was relocated to the Cannon House Office Building from the smaller Longworth House Office Building under the auspices of the Beauty Shop Committee. 2015 renovations In January 2015, a top-to-bottom renovation of the Cannon House Office Building began. Completion is expected to take ten years and cost $752.7 million. Initially, renovation will be focused on upgrading the building utilities, but will progress on to a wing-by-wing exterior and interior reconstruction.
