"Rehabilitation and revitalisation of housing estates mostly takes place on the premise of stronger environmental links of the residents to the housing environment. Especially to one's own flat or house, but also to the local surrounding. If the identification with the flat or house increases, the environmental responsibility will increase as well, and the interest in an intact housing environment will also increase. By means of three examples, the redevelopment area Divis Flats (Belfast/Northern Ireland), the "Block 6 Projekt" in Hamburg_Steilshoop and the housing estate Neckarstadt-Ost/Mannheim (both in Germany) it will be shown that this rehabilitation approach has been successful. The intention of this paper for an intensive session is for that reason not a "pro or contra discussion" about this rehabilitation approach. The question to be discussed is rather: how can such rehabilitation approaches work ill the future of so called globalisation and flexibilisation? The theories behind such approaches as well as the ideas behind a large number of integrative housing projects like neighbourhood units, the "Gartenstadt Bewegung" (garden city movement) or working class house_building, are based on the principle of a better environmental link through more identification with the house and the housing estate. Several studies about the future of labour organisation assume more flexibilisation, more changes of employment and as a result of these changes a shorter time of living in one estate. A shorter time of' staying in one place, more frequent removals can lead to a “why should I have any interest in my local environment? I'll live here for just a short time” attitude. This makes it more difficult to create an identification with the flat/house and the local environment. What impact could the shorter time of staying have on future rehabilitation programmes? Is it possible to organize new rehabilitation programmes with the current rehabilitation approaches, in the face of huge economical changes and more flexibility and mobility? Or do we need a new theoretical framework? If so, what are the theoretical and political alternatives?"
