Levittown. This fully planned, six-home style residential community was conceived by the builder, William J. Levitt. The first family moved in, June 23, 1952. When completed in 1957, Levittown contained 17,311 homes on 5,750 acres, designed for a population of 70,000. It expanded on the pattern set by Levittown, N.Y. (built 1947-51) and was a landmark in the development of suburban housing in the United States.
