The White House is located on Pennsylvania Avenue in Washington, D.C. It has been the home of every United States President since John Adams took up residence here in 1800. The building was designed by architect James Hoban and constructed in the Neoclassical Style between 1792 and 1800. In 1814, during the War of 1812, the White House was set on fire and gutted by the British Army during the Burning of Washington, forcing James Madison to take up residence in the Octagon House for the remainder of his term. His successor, James Monroe, was the first president to live in the newly reconstructed mansion in 1817. Over the years construction has continued on the house, including the addition of the south portico in 1824, the north portico in 1829, the West Wing in 1901 and the Oval Office in 1909. In 1948, during Harry Truman's term in office, the White House was completely overhauled, with a new steel frame being built, along with rebuilding of the interior rooms. The building has been updated, renovated, restored and redecorated many times over the years, most notably under the supervision of First Lady Jacqueline Kennedy in the early 1960's.
