And that is a miracle of itself. Most existing cohousing has been created in the face of hostile banks, local governments, etc. And still these middle class firebrands persevered and built multi-family developments. Groups of strangers volunteered hundreds of hours using cooperative processes, and put thousands of dollars of personal money at risk, in order to have more community for themselves and their children. And there are dozens of these places, and every year more and more come on line.
Community building is great stuff.
There are lots of niches for improving relationships between neighbors of all kinds and there is tons of work to do. So grab a shovel and start planting those seeds. Cohousing is just one of the packages the seeds come in. And if you expect cohousing to change dramatically from its current form, and become a mission centered community form to provide affordable housing, well, I think you are likely to be disappointed.
