The White House is the official residence and workplace of the president of the United States. Located at 1600 Pennsylvania Avenue NW in Washington, D.C., it has served as the residence of every U.S. president since John Adams in 1800 when the national capital was moved from Philadelphia. The White House is also a metonym for the Executive Office of the President.
The residence was designed by the Irish-born architect James Hoban in the Neoclassical style. Hoban modeled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Constructed between 1792 and 1800, its exterior walls are Aquia Creek sandstone painted white.
