Cohousing is a community design model where residents occupy private dwellings supplemented by an extensive shared common house. The common house typically includes a large kitchen and dining room (where the community shares meals several times per week), laundry facilities, guest rooms, children’s play areas, and community meeting space.

The cohousing model dramatically reduces per-household infrastructure costs, ecological footprint, and living expenses while increasing social connection. Research consistently shows that cohousing residents report higher levels of social connection and lower levels of loneliness than residents of conventional housing. They also consume significantly less energy per capita due to shared appliances, smaller private spaces, and behavioral influences of community living.
