Senior Co-Housing: A Systematic Review of Housing Models for Older Adults

This systematic review examines senior co-housing as an alternative to traditional care, combining private living with shared spaces. Based on 26 peer-reviewed articles (1986–2025), it identifies four key themes: social wellbeing, participatory governance, spatial design, and policy sustainability. Senior co-housing fosters autonomy and reduces loneliness, but faces challenges in affordability, scalability, and cultural acceptance. The literature is largely qualitative, with few longitudinal studies. The review highlights research gaps and calls for future work on equity, technology, and cross-cultural adaptation, positioning senior co-housing as a socially embedded response to the complexities of aging.
