The White House is the official home and principal workplace of the President of the United States of America. The house is built of white-painted Aquia sandstone in the late Georgian style. It is located at 1600 Pennsylvania Avenue in Washington, D.C. As the office of the U.S. President, the term "White House" is used as a metonym for a U.S. president's administration. The property is owned by the National Park Service and is part of "President's Park."

The building was originally referred to variously as the "President's Palace," "Presidential Mansion," or "President's House." Dolley Madison called it the "President's Castle." There is a common misconception that the term "The White House" wasn't used until after the War of 1812, when the mansion was burned and re-painted. However, the earliest evidence of the public calling it the "White House" was recorded in 1811, three years before the House was set on fire. The name "Executive Mansion" was used in official contexts until President Theodore Roosevelt established the formal name by having the de facto name "White House–Washington" engraved on the stationery in 1901. President Franklin Roosevelt changed his letterhead to "The White House" with the word "Washington" centered beneath. That convention remains today.
