Gadehavegård is a social housing development area, owned by Danske Funktionærers Boligselskab (DFB) and located in Høje Taastrup, east of Copenhagen. This chapter explores how the Gadehavegård demonstrator is answering two main issues in the area: the need for renovation of the residential area and empowering current residents in the decision-making process for such a transformation. The activities of the Desire demonstrator highlighted several key learnings. A major focus is on redefining tendering processes by incorporating participatory design principles, based on local needs, particularly those of young people. This approach challenges traditional roles and ensures designs reflect community input. Architects are encouraged to apply these principles before the tendering process begins, supplementing cost-focused assessments with spatial quality assurance. The project also emphasizes the importance of prominent circularity and accessible green spaces to enhance well-being, integrating nature into the participatory process. Involving youth in co-design fosters empowerment and rethinks power dynamics in social housing transformations.
