Designed in the International Style, the William L. 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 Slayton, who was an active part of the Southwest urban renewal project.
The house 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, and its use in the Slayton House still represents one of its few applications in the United States.
