Vermont's Cobb Hill Cohousing Community has a home for sale. In the best endorsement of the community, the sellers are not moving away, just moving up the hill to a different house:
"The home is a private unit (one bedroom) in the Common House of Cobb Hill. Share huge beautiful kitchen with other apartment dwellers and community. Includes den, fireplace, laundry, root cellar, finished attic, wood shop with all kinds of tools, and much more."
Cobb Hill was founded by Donella Meadows, the author of Limits to Growth.
