Vienna and the surrounding area are growing rapidly: by 2025 the metropolis of Vienna is expected to increase by 400,000 people. Especially the transformation of the existing housing stock into liveable, intensively used districts is an important challenge for Vienna. On the administrative borders, the City of Vienna wants to define so-called ‚regional cooperation areas‘ together with the neighbouring municipalities. On the initiative of the City and Region Management (SUM), the City of Vienna and the municipality of Vösendorf are working together on solutions for the transformation and design of the growing city. 

Within the framework of the URBACT III project ‚SUB>URBAN. Reinventing the fringe‘ there is the chance to develop the first Regional Cooperation Area in Vienna-Liesing and Vösendorf as a pilot project in a learning network with eight other European cities.
