Neighbourhood Unit

Definition

The neighbourhood unit names the planning device that subdivided the postwar city into "clearly defined and well-rounded blobs" of 6,000–10,000 people, "grouping of an estate, firstly around a community centre, and then also in conjunction with certain patterns of vehicular access" (p. 98). Its sources: the Utopian tradition, but terminologically the United States of the 1920s — "the writings and plans of Clarence Perry, Clarence Stein and Henry Wright"; Lewis Mumford's demand that "the playground and open spaces and small meeting halls were treated as an integral part of the housing development" (p. 97). In Britain it was institutionalised by Abercrombie and Forshaw's County of London Plan (1943) and the Dudley Report and Housing Manual of 1944, with the primary school as the real determinant: "no child under eleven should have to cross a major road en route to school" (p. 98). All the early New Towns "adopted the neighbourhood division" (p. 99).

Glendinning & Muthesius frame the unit as the town-planners' practical answer to 'community': "it appeared that 'community' had found a practical application and a convincing synonym in 'neighbourhood'" (p. 99) — but also as the device whose career was exceptionally short. "Very soon the town planners' image… became tainted through the criticism and the jealousy of neighbouring professions": sociologists attacked its "unscientific" notions of community, architects its "bureaucratic interference with design" — by 1952 "the subject has now lost its popular appeal" (p. 99). Its sociological demolition (Glass, Kuper, Dennis) and the designers' counter-concepts ('urban design', Townscape, the Smithsons' cluster) form the concept's afterlife; its purest remnant, the Radburn layout, "served chiefly as a model for the separation of traffic" (p. 100).

This page requires fuller treatment — created at the Glendinning & Muthesius ingest; Perry's own texts and the Radburn lineage's built record await fuller sources.

Key Thinkers

• Miles Glendinning & Stefan Muthesius — the concept's historians in the UK register: the Perry/Stein/Wright genealogy, the Abercrombie institutionalisation, and the collapse of the unit's popular appeal (1994).
• Clarence Perry, Clarence Stein & Henry Wright (not paged — see log) — the American inventors of the unit and the Radburn layout.
• Lewis Mumford (not paged — see log) — the unit's theorist: the neighbourhood as an integral part of housing development.
• Patrick Abercrombie & J. H. Forshaw (not paged — see log) — the County of London Plan institutionalisation; the 'egg-basket' map.
• Jane Jacobs — the unit's greatest critic (the "neighbourhood" as one of planning's "pseudo-scientific" tools; real neighborhoods as self-organized — 1961, in this wiki's account).

Related Concepts

• public-housing — the housing programme the unit organized: estates as schools-and-greens before they were dwellings.
• mixed-development — the dwelling-type formula that filled the unit's fabric.
• zeilenbau — the layout doctrine the unit's greens accommodated.
• the-social — the sociological warrant the unit promised and could not deliver.
• ground-rules-and-social-maps — Ardener's alternative geography of community: social mapping without planning blobs.
• community-resources — Jacobs's three categories: the actual content the unit's community centre tried to plan.

• The Death and Life of Great American Cities (Jacobs 1961) — the unit's demolition from the street level: the neighborhood as planned artifact versus the self-organized city district (1961, in this wiki's account).

Open Questions

• The unit was a practical device (school catchment, road hierarchy) that carried a sociological theory (community). When the theory collapsed but the school arithmetic survived, what was the device still planning for?
• Glass's finding that "physical demarcations between districts or neighborhoods do not coincide precisely with the locations of the inhabitants' social activities" (p. 102) is the wiki's clearest bridge to Ardener's ground-rules-and-social-maps: can the two be made into one claim?
• Is the neighbourhood unit the planning side of the architectural-determinism problem — the blob as prescribed community — or its own, distinct failure mode (scale)?
• What survived: the school-walk rule is still live in contemporary planning guidance. Does a dead concept's arithmetic keep planning power?
