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 has been the residence of every U.S. president since John Adams in 1800, and the term is often used by journalists as a metonym to refer to the acts of the President and his top advisors.
The house was designed by Irish-born James Hoban and built between 1792 and 1800 of white-painted Aquia Creek sandstone in the Neoclassical style. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) expanded the building outward, creating two colonnades that were meant to conceal stables and storage.
The architecture of the United States demonstrates a broad variety of architectural styles and built forms over the country's history of over four centuries of independence and former British rule.
Architecture in the United States is as diverse as its multicultural society and has been shaped by many internal and external factors and regional distinctions. As a whole it represents a rich eclectic and innovative tradition.
