The Collective House Assembly embraces a fairly loose and self-assigned definition of what constitutes a "co-operative" or "collective" house. If you think you live collectively with your housemates or you want to live collectively eventually, you are welcome to come to our Assembly meetings and join the discussion.
There are, however, some very specific kinds of collective and co-operative living situations, described below. Definitions here were organized by Johnn. See also his very helpful document that is added as an attachment at the bottom of the page.
“Intentional Community is an inclusive term for ecovillages, cohousing communities, residential land trusts, communes, student co-ops, urban housing cooperatives, intentional living, alternative communities, cooperative living, and other projects where people strive together with a common vision.” from ic.org
“Cohousing is a type of collaborative housing in which residents actively participate in the design and operation of their own neighborhoods. ... The physical design encourages both social contact and individual space. Private homes contain all the features of conventional homes, but residents also have access to extensive common facilities such as open space, courtyards, a playground and a common house.” from the Cohousing Association of the United States
“A commune is an intentional community of people living together, sharing common interests, property, possessions, resources, work, and income.” from Wikipedia
“Ecovillages are urban or rural communities of people, who strive to integrate a supportive social environment with a low-impact way of life. To achieve this, they integrate various aspects of ecological design, permaculture, ecological building, green production, alternative energy, community building practices, and much more.” from the Global Ecovillage Network
