The White House is the official residence and workplace of the President of the United States and the First Family. It is located at 1600 Pennsylvania Avenue in Washington, D.C., and it has been the residence of every U.S. president since John Adams in 1800.
The residence was designed by Irish-born architect James Hoban 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.
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 on the American Institute of Architects list of "America's Favorite Architecture".
