The White House is the official residence and workplace of the president of the United States. It is located at 1600 Pennsylvania Avenue NW in Washington, D.C., and has been the residence of every U.S. president since John Adams in 1800.[3] The term "White House" is often used as a metonym for the president and his advisers.

The residence was designed by Irish-born architect James Hoban[4] in the neoclassical style. Hoban modelled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Construction took place between 1792 and 1800, using Aquia Creek sandstone painted white. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) added low colonnades on each wing that concealed stables and storage.[5] In 1814, during the War of 1812, the mansion was set ablaze by the British Army in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began almost immediately, and President James Monroe moved into the partially reconstructed Executive Residence in October 1817. Exterior construction continued with the addition of the semi-circular South portico in 1824 and the North portico in 1829.

Because of crowding within the executive mansion itself, President Theodore Roosevelt had all work offices relocated to the newly constructed West Wing in 1901. Eight years later, in 1909, President William Howard Taft expanded the West Wing and created the first Oval Office, which was eventually moved as the section was expanded. In the main mansion (Executive Residence), the third-floor attic was converted to living quarters in 1927 by augmenting the existing hip roof with long shed dormers. A newly constructed East Wing was used as a reception area for social events; Jefferson's colonnades connected the new wings. The East Wing alterations were completed in 1946, creating additional office space. By 1948, the residence's load-bearing walls and wood beams were found to be close to failure. Under Harry S. Truman, the interior rooms were completely dismantled and a new internal load-bearing steel frame was constructed inside the walls. On the exterior, the Truman Balcony was added. Once the structural work was completed, the interior rooms were rebuilt.

The modern-day White House complex includes the Executive Residence, the West Wing, the East Wing, the Eisenhower Executive Office Building (the former State Department, which now houses offices for the president's staff and the vice president) and Blair House, a guest residence. The Executive Residence is made up of six stories: the Ground Floor, State Floor, Second Floor, and Third Floor, as well as a two-story basement. The property is a National Heritage Site owned by the National Park Service and is part of the President's Park. In 2007, it was ranked second[6] on the American Institute of Architects list of "America's Favorite Architecture".
