Abstract. On 22.06.2021 the new law i.e., “Gesetz zur Mobilisierung von Bauland” (Baulandmobilisierungsgesetz) entered into force in Germany, enabling municipalities to give priority to building on inner-city open spaces at a higher building density. Especially for rural communities, where there are many underutilized properties and inner-city open spaces, there is great potential for redensification, which is addressed by the new legislation. Depending on the attractiveness of urban areas, many of the surrounding rural communities will experience an influx of population in the coming decades. The goal of this research work is to develop an interactive Web GIS application showing the housing potential and demand according to socio-demographic scenario for such a rural community. This application serves as a decision support system for the stakeholders i.e., the urban planning department of the municipality to re-densify the urban structure in a sustainable way. This work helps to build up a comprehensive geodatabase including all relevant physical, ecological, economic, and social aspects, which further locates and quantifies the potential open spaces and buildings gaps being suitable for redevelopment. Here, the housing potentials are divided into different constructional realization categories, which can be used for a realistic urban planning. The analyzed and calculated results will be visualized in a Web GIS application where the user is able to query and edit on different urban development scenarios.
