Abstract
Against the background of the current housing affordability crisis, a new wave of ‘collaborative housing’ (CH) is developing in many European cities. In this paper, CH refers to housing projects where residents choose to share certain spaces and are involved in the design phase. While many authors point to the alleged economic benefits of living in CH, the (collaborative) design dimension is rarely mentioned in relation to affordability. This paper seeks to fill this knowledge gap by identifying design criteria used in CH to reduce building costs, increasing this way its affordability. We carry out a comparative case study research, where we assess the design phase of 16 CH projects in different European cities. Findings suggest that collaborative design processes increase the chances of improving housing affordability, mainly due to the often-applied needs-based approach and the redefinition of minimum housing standards.
