Biography06/21/2007 | "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. The term "White House" is often used as a metonym for the president and their advisers. The residence was designed by Irish-born architect James Hoban in the neoclassical style. Construction took place between 1792 and 1800 using Aquia Creek sandstone painted white. 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." -- Wikipedia
