I see on Brownstoner that the Brooklyn cohousing group has chosen a location for their utopian vision of a communal living space. It sounds like a great site: Fort Greene’s former St. Michael’s Church property. Here from Brownstoner:

The 10 member households and 17 associate households of the Brooklyn Cohousing group
have found a site for their social and housing experiment: Fort
Greene’s former St. Michael’s church property. "When our project is
complete, our community will share three buildings surrounding a
7,500-square-foot inner courtyard of gardens, green space and
children’s play areas," they wrote in an email to interested parties.
"In addition, we will share extensive interior common space and share a
process of decision making that empowers everyone in the community."
This will be a more co-operative co-operative, based on the Danish
model of co-housing where folks own individual property as well as some
communal spaces.
