The deterioration and decay of the inner urban areas is now becoming an ever-increasing problem for planners. Weak planning and especially poor housing are presented as the biggest contributing factors to urban decay and consequential rises. The aging of buildings is a normal process, but it does not necessarily mean that it must be replaced by new buildings. Restoration and rehabilitation along with preservation of existing buildings can greatly contribute to solving the poor conditions that characterize the inner urban areas. The example of the Transvaal district in Leeuwaarden shows how such an attempt can be made. The success of this project is the result of good organization and management as well as the provision of information. Local enthusiasm and participation have played a major role.
