William L. Slayton House (and interior)

The William L. Slayton House located in the Cleveland Park neighborhood in Washington, D.C., is a house that was designed by I.M. Pei in the International Style.

The Slayton House is one of only three houses known to have been designed by world-renowned architect I.M. Pei. Pei, primarily a corporate architect, but best known for municipal buildings and art museums, consented in 1959 to design a house for his friend and colleague.

The house, designed in the International Style, is located in the Cleveland Park Historic District. It was completed in 1960 and features a triple-vault, poured-in-place concrete roof as its most distinguishing feature. The front and rear elevations are all glass, resulting in a house that is largely transparent and open in plan. The Slayton House is significant not only for its architecture but also for its structure. The poured-in-place concrete arched roof was an important technological innovation, the Slayton House remains the pre-eminent residential example in the United States.
