White House Sub-Basement

The Sub-Basement

The White House Sub-Basement is not original to the structure. It was dug during the Truman reconstruction in 1949, and staircases off the Center Hall on the east side were built in space formerly occupied by larger lavatories off the Library and Vermeil Room. These staircases have small windows that open into window nooks on the east side.

The Sub-Basement contains much of the mechanical necessities of the White House. There are likely two sub-basement levels under the White House. Just off the stairs down are dressing rooms for guests who come to the White House to perform.
