Conceptualized by Frank Lloyd Wright (1932- 1959), Broad Acre city was a vision of multicentered, low density (supposedly 5 people per acre), auto-oriented suburbia. Each family would be given one acre (4,000 m²) on which to build a house and grow food, from the federal land reserves. Land would be taken into public ownership; then granted to families for as long as t hey used it productively. The city was considered to be (almost) fully self-sufficient. "More light, more freedom of movement and a more general spatial freedom in the ideal establishment of what we call civilization."

In 1935, Le Corbusier combined the efficiency of the high rise typology with the philosophy of the garden city movement in La Ville Radieuse (The Radiant City). Despite receiving criticism by contemporary critics for their inherent segregation and sterility, the plans are a significant contribution of the Modernist movement and went on to influence planned cities such as Brasilia, Brazil, in the 1960's.

Arcosanti is a projected experimental town with a molten bronze bell casting business in Yavapai County, central Arizona, 70 mi north of Phoenix, at an elevation of 3,732 feet. Its arcology concept was posited by the Italian-American architect, Paolo Soleri.

Robert Owen (1771-1858) was a Welsh textile manufacturer, social reformer, and one of the founders of utopian socialism and the cooperative movement. Owen is best known for his efforts to improve the working conditions of his factory workers and his promotion of experimental socialistic communities.To test the viability of his ideas for self-sufficient working communities, Owen began experiments in communal living in America in 1825. Among the most famous of these was the one established at New Harmony, Indiana. Of the 130 identifiable communitarian experiments in America before the American Civil War, at least sixteen were Owenite or Owenite-influenced communities. New Harmony was Owen's earliest and most ambitious experiment. In 1825 Owen used a portion of his own funds to finalise the purchase of an existing town that included 180 buildings and several thousand acres of land along the Wabash River in Indiana. Owen renamed it New Harmony and established the village as his preliminary model for a utopian community. Owenism, among the first socialist ideologies active in the United States, is considered the starting-point of the modern Socialist movement in the United States. The utopian community at New Harmony was a centre for educational reform, scientific research, and artistic expression. Although he intended to build a "Village of Unity and Mutual Cooperation" south of town, his grand plan was never fully realised, and Owen returned to Britain to continue his work. The New Harmony communal experiment proved to be an economic failure, lasting about two years, but it attracted more than a thousand residents by the end of its first year. Other utopian experiments in the United States included communal settlements at Blue Spring, near Bloomington, Indiana; Yellow Springs, Ohio; and the Owenite community of Forest ville Commonwealth at Earlton, New York, as well as other projects in New York, Pennsylvania, and Tennessee. Nearly all of these experiments ended before New Harmony was dissolved in 1827.
