Redevelopment and Modernisation

  • Graham Hallett


A city is an elaborate mosaic, in which pieces are continually wearing out and being replaced. Whether redevelopment occurs, the form it takes, and the districts where it occurs, involves complex factors including the social conditions of the district, local resistance to redevelopment, town planning policy, investment in new transport routes. For this reason, it is impossible to consider an individual site completely in isolation from its surroundings, and there is no clear-cut relation between a building’s age or condition and redevelopment. Replacement occurs only when there is strong demand for a site, and when the existing building becomes inadequate. But the simple theory based on building value and site value is a useful framework for analysis, provided it is used with an appreciation of the many ‘external’ factors which impinge on these values.

    The defects of British post-War buildings are beginning to be appreciated by hard-headed developers since post-War offices have been extremely costly to heat and maintain. Clients are beginning to lay more emphasis on the future costs of maintenance, so as to minimise long-run, rather than merely initial, costs. For public buildings, the need is for ‘negative feedback’.Google Scholar

    Density can be measured in various ways e.g. the floor area/site ratio or ‘bed-spaces per acre’, which is usually regarded as the best indicator of persons per acre. The Layfield Committee assumed that the number of habitable rooms and persons was roughly equal, which is surprising, since the average number of persons per room is around 0.6.Google Scholar
