Been on this path for over 10 years. I know these small communities could be the key to a better future.... but each one works in different ways.
It is said that communal housing works well with a maximum of 11 people, any more and too many problems arise.
I like your design idea tho. Personally I like the single family unit thing. For now, we are just one family, we built a barn because on paper, that's what it is, and that means lower taxes...
We bought land in a place that isn't at all good for this kind of community. Loads of regulations, high taxes but we're close to NYC and that's where we tapped out community income from! Plus our friends and family are all here.
Trust me I want all the fancy things for a maker space but for now... baby steps
