‘Design with (addiction) Care’ is a reflection on the role of an architect within the humanization of addiction care, primarily the design of the typology of a hostel. It is deeply rooted in the studio theme of the scarred city, where both the vulnerable scarred urban tissue as well as vulnerable people demand careful architectural reasoning. The thesis combines several methods to obtain an understanding of how architectural decision-making affects the use and experience of buildings over time. Concomitantly it examines how the perspectives of different stakeholders influence the design process. Analyzing the perspectives of architects, residents, managers, social workers, directors, local residents, professors and municipalities has contributed to a reflection on an architect's challenges, limitations and possibilities within our multidisciplinary profession.
