This study focuses on research about the spatial and social living environment of elderly with care demand. It developed from the urge for new ways of thinking about the design of care for elderly in neighborhoods and houses. In a collaboration between an architectural school of education and a social housing association housing the elderly, an interdisciplinary research method to come to new models for elderly living was developed. The study describes the method and main findings. In the Netherlands the demographic transition to an aging society runs parallel with transitions in the policy and practice of elderly care. Due to a steep rise in the cost of care and a shortage of staff, care moves away from institutional buildings and organizations towards a more informal support network with professionals in the background. The research questions addressed in this study concern the everyday life of elderly needing care. Within a one-week stay in a nursing- or elderly care home, participating in the daily life, we aim to get answers through anthropological and par-ticipatory research to understand, document and visualize the needs and living conditions of elderly today. Finally, these data are translated into architectural design. We claim that the person whom we design for should be the first to meet and talk to. In that way we learn about their wishes, needs and capabilities. This argument was our starting point of collaboration. Our methodology leads to unexpected results. The study will show main findings and topics of discussion.
