A residential cluster development, or open space development, is the grouping of residential properties on a development site to use the extra land as open space, recreation or agriculture. It is increasingly becoming popular in subdivision development because it allows the developer to spend much less on land and obtain much the same price per unit as for detached houses. The shared garden areas can be a source of conflict, however. Claimed advantages include more green/public space, closer community, and an optimal storm water management. Cluster development often encounters planning objections.[citation needed]
According to William H. Whyte, the author of “Cluster Development”[1] there are two types of cluster development: townhouse development and super development. Examples of townhouse development include Morrell Park, Philadelphia, Pennsylvania, Hartshone in Richmond, and Dudley Square in Shreveport. Examples of super development include Reston, Virginia, Crofton, Maryland, and Americana Fairfax in Virginia.
