Broadacre City was an urban or suburban development concept proposed by Frank Lloyd Wright throughout most of his lifetime. He presented the idea in his book The Disappearing City in 1932. A few years later he unveiled a very detailed twelve by twelve foot (3.7 × 3.7 m) scale model representing a hypothetical four square mile (10 km²) community. The model was crafted by the student interns who worked for him at Taliesin, and financed by Edgar Kaufmann. It was initially displayed at an Industrial Arts Exposition in the Forum at the Rockefeller Center starting on April 15, 1935. After the New York exposition, Kaufmann arranged to have the model displayed in Pittsburgh at an exposition titled "New Homes for Old", sponsored by the Federal Housing Administration. The exposition opened on June 18 on the 11th floor of Kaufmann's store. Wright went on to refine the concept in later books and in articles until his death in 1959.
Many of the building models in the concept were completely new designs by Wright, while others were refinements of old ones, some of which had been rarely seen.
Broadacre City was the antithesis of a city and the apotheosis of the newly born suburbia, shaped through Wright's particular vision. It was both a planning statement and a socio-political scheme by which each U.S. family would be given a one acre (4,046.86 m²) plot of land from the federal lands reserves, and a Wright-conceived community would be built anew from this. In a sense it was the exact opposite of transit-oriented development. There is a train station and a few office and apartment buildings in Broadacre City, but the apartment dwellers are expected to be a small minority. All important transport is done by automobile and the pedestrian can exist safely only within the confines of the one acre (4,046.86 m²) plots where most of the population dwells.
In his book Urban Planning Theory since 1945, Nigel Taylor considers the planning methodology of this type of cities to be Blueprint planning, which came under heavy criticism in the late 1950s by many critics such as Jane Jacobs, in her book The Death and Life of Great American Cities.
