The West Wing
The West Wing is that part of the United States's Presidential mansion that houses the offices of the President and his or her staff. The wing is two storeys tall, and houses the Oval office, the President's office, as well as offices for the National Security Advisor, an office for the Vice President, Press secretary, their subordinates, and a Secret Service security detail.
The West Wing is linked to The central part of The White House by a long covered hallway. A similar sized outbuilding, The East Wing, is linked by a similar covered hallway on the opposite side of The White House. Clever landscaping hides these hallways from visiting tourists.
A popular television drama, about a fictional President, was entitled The West Wing
