The Form-based Development Plan: bridging the gap between theory and practice in urban morphology
The format of local development plans and site-specific guidance tends to be based on land-use allocations rather than physical form. This approach has serious limitations, especially when dealing with urban design issues. A solution is available in a format that takes the outline of physical form as its starting point with land use as a subsidiary consideration. This approach can be incorporated into spatial planning policy. Furthermore, urban design principles imply perimeter block structures whose approximate sizes are largely predetermined and can be incorporated in site-specific guidance. This paper draws attention to innovation in planning practice in Britain and a particular example is described in detail. Local spatial policy for the town of Chelmsford made physical implications explicit. Planning briefs identifying both the perimeter block form and the location and character of the urban spaces were successful in improving the standard of design of new development.
