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. 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 (4,000 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 (4,000 m²) plots where most of the population dwells.
Some of the earlier garden city ideas of the landscape architect Frederick Law Olmsted and the urban planner Ebenezer Howard had much in common with Broadacre City, save for the absence of the automobile, born much later. More recently, the development of the Edge city is like an unplanned, incomplete version of Broadacre city.
