The garden city movement is a method of urban planning that was initiated in 1898 by Sir Ebenezer Howard in the United Kingdom. Garden cities were intended to be planned, self-contained communities surrounded by "greenbelts" (parks), containing proportionate areas of residences, industry and agriculture.

Inspired by the Utopian novel Looking Backward, Howard published his book To-morrow: a Peaceful Path to Real Reform in 1898 (which was reissued in 1902 as Garden Cities of To-morrow). His idealised garden city would house 32,000 people on a site of 6,000 acres (2,400 ha), planned on a concentric pattern with open spaces, public parks and six radial boulevards, 120 ft (37 m) wide, extending from the centre. The garden city would be self-sufficient and when it reached full population, another garden city would be developed nearby. Howard envisaged a cluster of several garden cities as satellites of a central city of 50,000 people, linked by road and rail.

Howard’s To-morrow: a peaceful path to real reform sold enough copies to result in a second edition, Garden Cities of To-morrow. This success provided him the support necessary to pursue the chance to bring his vision into reality. Howard believed that all people agreed the overcrowding and deterioration of cities was one of the troubling issues of their time. He quotes a number of respected thinkers and their disdain of cities. Howard’s garden city concept combined the town and country in order to provide the working class an alternative to working on farms or ‘crowded, unhealthy cities’.
