The name Executive Mansion was used in official contexts until President Theodore Roosevelt established the formal name by having the de facto name White HouseâWashington engraved on the stationery in 1901.
William Taft hired architect Nathan Wyeth to expand the executive wing in 1909, resulting in the formation of the Oval Office as the presidentâs work space. In 1913, the White House added another enduring feature with Ellen Wilsonâs Rose Garden. A fire during the Hoover administration in 1929 destroyed the executive wing and led to more renovations, which continued after Franklin Roosevelt entered office.
