Broadacre City was an urban or suburban development concept proposed by Frank Lloyd Wright throughout most of his lifetime.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.It was initially displayed at an Industrial Arts Exposition in the Forum at the Rockefeller Center starting on April 15, 1935.All important transport is done by automobile, and the pedestrian can exist safely only[citation needed] within the confines of the one-acre (0.40-hectare) plots where most of the population dwells.The R. W. Lindholm Service Station in Cloquet, Minnesota, shows some of Wright's ideas for Broadacre City.
