Radburn, New Jersey, USA 2001

One of the major reasons for the popularity of the internal reserve in the 1920s was the recognition of the potential danger posed by the wider adoption of the automobile. Radburn design - so named for its initial template construction at Radburn, NJ - is a further adaptation of the internal reserve concept to accentuate separation of car and pedestrian (particularly the juvenile pedestrian).

One of the notable and interesting elements of attitudes to radburn and internal reserve design manifests in the common assumption that the intention of designers of internal reserves were that houses would face into them. This, generally speaking, is not the case. More commonly the expectation was that houses would have views into reserves from kitchen or other domestic areas so that the occupants of houses (usually, mother) could see into reserves and monitor playing children. From Clarence Perry's Neighbourhood and Community Planning 1929 p. 63
