Levittown

Sales flyer for the Levittowner.
The heart of Levittown was the mass-produced, single-family house. Levitt sacrificed individuality and custom design for low-cost efficiency. Still, his Pennsylvania development featured six house models, each in several different styles and model years. Levitt boasted that he had created "the least monotonous mass housing group in the country."

"The brainchild of developer William J. Levitt, Levittown, Pennsylvania was the largest planned community constructed by a single builder in the United States. By the time it was completed in 1958, the development occupied over 5500 acres in lower Bucks County and included churches, schools, swimming pools, shopping centers and 17,311 single-family homes.
To its 70,000-plus residents, Levittown represented the American Dream of homeownership. To many others, Levittown epitomized postwar suburbia—a place often criticized but widely copied. "
