The large high-density inner city housing projects of the 1950s and 1960s are no longer perceived as ideal homes. This housing has become vandalised and neglected, many units are hard to let and some abandonned, resulting in a loss of useable housing stock for local authorities. Normal maintenance programmes have proved inadequate in solving the problem. This paper will examine the methods used to rehabilitate certain estates in London, including user-participation in the decision process, the varying use of resources, and the costs involved. An assessment will be made of the results obtained in terms of tenant satisfaction and long-term viability of the housing.
