This research deals with the affordable housing problem for housing seekers who cannot find a house according to their needs and financial capacity; the single person household (solo) and couples with vulnerable financial and social status. Furthermore, it investigates whether the housing form "collective living", under the financing of cooperatives, can provide a solution for them. The research runs in parallel with the graduation studio Advanced Housing Design and is the backbone of my individual urban design in the collective master plan. From the themes diversity and community, the research’s collective living is further investigated. Relationships between private units, shared space in cluster homes and collective spaces within the building and the relation of the residential complex with the master plan are explained in this study. The design is part of the master plan in Rotterdam Blijdorp where I will introduce the co-housing with shared spaces. By means of literature studies and case studies, this research will be supported in order to arrive at a concluding design vision and later a final design based on this, new and rather unknown form of living in the Netherlands, co-living.
