1111 Pennsylvania Avenue is a mid-rise Postmodern office building located in Washington, D.C., in the United States.

[4] The Raleigh Hotel closed in 1954, and by 1965 developer Jerry Wolman had purchased the site and proposed building the current structure.

[7] Because of restrictions imposed by the Pennsylvania Avenue National Historic Site legislation, Wolman agreed to move the building line back from Pennsylvania Avenue by 50 feet (15 m) and keep the building's height to 135 feet (41 m), although in exchange for the loss of interior square footage District of Columbia zoning officials gave him permission to cantilever the building over the sidewalk on 12th Street at a height about 30 feet (9.1 m) above the street.

[6][9] Dreyfuss worked closely on the building with John Woodbridge, a staff architect for the President's Council on Pennsylvania Avenue and a member of the firm Skidmore, Owings and Merrill.

[6] Purchased by local surgeon Laszlo Tauber, one of the richest men in the D.C. area, the structure underwent a $40 million renovation between 2000 and 2002.

[6] The facade was replaced with a Postmodern style more in tune with the nearby Evening Star building addition next to it on Pennsylvania Avenue, and two stories were added.
