Urban regions are the most important areas for housing and economic activities in Austria. The big stock of social housing coupled with the openness to a broad section of the population are responsible for a wide selection of affordable homes in urban regions. However, housing costs went up in recent years. Since strategic approaches to housing are rare, a change is needed. Therefore, key points of a housing strategy in urban regions have been defined in this thesis. This strategy includes housing demand forecasts, improvement of accessibility to social housing and construction of new tenements. Building on a literature research, an analysis of housing data in urban regions, several interviews with planning and housing experts and two case studies (Leoben and Weiz), different suggestions of action have been released. Furthermore, a process to improve access to social housing has been established. ^The analysis of housing data shows that social housing is of high importance within urban regions. 85% of all social housing is located in urban regions and therefore part of one of the 34 Austrian urban regions. Core cities fulfil an important function as they provide disproportionate numbers of social housing. To improve access to social housing, cooperation between municipalities is needed. Cooperation is possible trough different models. This ranges from informal to institutionalized cooperation within urban regions. In order to make housing a regional topic, stake-holders need to put it on the agenda of regionals councils. The framework conditions and the resulting challenges are diverse in numerous urban regions. Therefore, a regional urban housing strategy must be oriented differently according to the challenges. This was illustrated by the medium-sized urban region of Leoben and the small-sized urban region of Weiz. ^Leoben has a large social housing stock and must focus on better cooperation with existing housing estates. Weiz, on the other hand, has a very small social housing stock. Particularly the area between Weiz and Gleisdorf is growing rapidly. Therefore, the focus within the urban regional must be on securing land for further social housing development, as wells as increased construction of social housing. A sufficient availability of affordable housing is essential for the development of a municipality in the sense of the residential population. Due to different functional merges within urban regions, cooperation on social housing and settlement development on a strategic level is necessary.
