The Radiant City plan proposed by Le Corbusier involved rebuilding cities using modern construction methods. It centered around large, pre-fabricated apartment buildings called les unites that would house thousands of residents. Les unites would be placed on stilts above the ground and connected by interior streets and elevators. Transportation and industry would be separated onto different roadway levels. However, critics argue that while Corbusier advocated for certain individual freedoms and leisure activities, his vision actually involved a paternalistic and bureaucratic form of authority that did not allow for individual voice or non-rational human behavior. His conception of a rationally-planned city did not account for the complexity and unpredictability of human nature.
