Innovative housing models to support shared use of space: the case study of Sonnwendviertel Ost in Vienna

Amidst the persistent urban expansion in European cities, the need for high-quality housing for growing populations remains a challenge. Integrating newly developed housing areas into the urban fabric and fostering a distinct local identity pose additional challenges. Despite extensive research in this realm, there exists a gap in the examination of the extent of shared space utilization in new housing developments. This study fills that gap by analyzing the quantity, quality, and diversity of space utilization in new housing projects, focusing on the development processes and maintenance methods. The research, conducted through site and case study analyses of Sonnwendviertel Ost development area in Vienna, underscores that the shared utilization of spaces is closely tied to distinct housing models with varied levels of financing and involvement of diverse actors. Consequently, it provides insights into the housing models and their configurations that best facilitate the development of shared use of spaces in housing construction. This, in turn, is perceived as instrumental in cultivating a more robust neighborhood identity and enhancing the livability of communities, thereby contributing to sustainable urban development. © The Author(s) 2024.
