This book presents a concise description and qualitative exploration of a new residential option for older adults: senior cohousing. It describes the practical, structural and communal aspects of senior cohousing and shares the lived experiences of actual residents. Pursuing an existential-phenomenological approach, the authors visited a selection of senior cohousing communities throughout the US and interviewed members to investigate their experiences in several regards: gathering together; developing the mission and architectural design; defining member expectations for the community; and engaging in cooperative self-management, consensus building, shared tasks and mutual activities as an ongoing way of life. In addition, the authors explored the benefits, challenges and surprises that community members have encountered along the way, and what these experiences have meant for their lives. Given its unique insights, the book offers a valuable resource for academics and all those working and interested in gerontology, sociology, psychology, nursing, public health, housing and the consumer sciences. It will also benefit active older adults who are considering new housing options.
