The White House is the official residence and principal workplace of the President of the United States. Located at 1600 Pennsylvania Avenue NW in Washington, D.C., it was built between 1792 and 1800 of white-painted Aquia sandstone in the late Georgian style and has been the residence of every U.S. President since John Adams. When Thomas Jefferson moved into the home in 1801, he (with architect Benjamin Henry Latrobe) expanded the building outward, creating two colonnades which were meant to conceal stables and storage.Today, the White House Complex includes the Executive Residence (in which the First Family resides), the West Wing (the location of the Oval Office, Cabinet Room, and Roosevelt Room), and the East Wing (the location of the office of the First Lady and White House Social Secretary), as well as the Old Executive Office Building, which houses the executive offices of the President and Vice President.
The White House is made up of six stories—the Ground Floor, State Floor, Second Floor, and Third Floor, as well as a two-story basement. The term White House is regularly used as a metonym for the Executive Office of the President of the United States and for the president's administration and advisors in general. The property is 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's List of America's Favourite Architecture.
