Public health should promote co-operative housing and cohousing.

In promoting healthier built environments, attention worldwide has focused largely on streetscapes and recreational spaces, with less regard given to housing form, in particular to the health effects of communal housing. Research demonstrates that communal housing models, such as cohousing and co-operative housing, promote social inclusion, and increase the perceived well-being and mental and physical health of residents, particularly of seniors. In Canada, relative to other countries, there is a paucity of evidence for the health effects of co-operatives and cohousing. Historically, some Indigenous communities constructed longhouses, connected dwellings situated around common areas, a form which may still be useful in promoting healthy communities. In this commentary, we suggest that improving access to co-operative and communal housing is an important area for public health involvement.
