This study investigated in what way vacant real estate in the Netherlands can be repurposed to meet the housing needs of the growing 65+ population. The study addresses two interrelated societal challenges: the severe housing shortage and the increasing demand for suitable elderly housing, as the number of people aged 65 and older continues to rise while current options for independent senior living remain limited. The research employed qualitative methods, starting with a literature review to outline elderly needs and preferences, and to explore the opportunities and barriers to repurposing real estate. This was followed by case study analysis of two case studies: De Getijden (a former school in Nijmegen) and De Benring (a former care home in Voorst), including semi-structured interviews with real estate experts and vital 65+ residents. The outcome of the study is an assessment framework, embedded in a step-by-step guide, to help evaluate whether vacant buildings can be repurposed to meet elderly housing preferences and needs. The framework was validated by a group of experts during a focus group session. The aim of the research was to develop a framework to help assess the suitability of vacant buildings for elderly housing, which can assist as a conversation tool in effective decision-making for developers, municipalities, architects, contractors, housing associations, and property owners or investors. Ultimately, this research supports the housing market by helping to address the needs of the aging population while stimulating housing flow through adaptive reuse strategies.
