This is totally la-la-land utopian dreams! Because, those house and barn won't be like that. You have to get rid of the single-family house ideas! Kill it! Kill it with fire!
Instead, you will have several large buildings.
Each person will get a suite of rooms. Bedroom, sitting room, bathroom, closet. Something close to a tiny apartment or a bed sit. And these go around the outside of the building. With a deck running around the exterior. So, each little-suite has an interior door, and an exterior door.
In the center of the house will be large rooms, for gaming/playing music with friends, for eating, and of course, a big communal kitchen.
You will not want a "barn" for your communal money making activities.
You need a real shop, that is set up for the economy-business you/community chooses.
And, of course, you will need a large greenhouse, with hail-shields.
I am glad that you are already thinking of small community homesteads. They are the future.
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
I would like to hear the ideas that go with maximum 11 people.
It is not a hard and fast rule, as there have been single families with more than that many family members living under a roof.
But, 11 disparate people and you will start running into some conflict. Each 1 added, creates more points of contention.
However, several large buildings is what will probably happen, and people will move between and that may fix things.
But, i also think the individual tiny-suites are a key element in putting more people closer together.
I also had ideas of building a great big stone fireplace wall. (you run the duct work, all back and forth in the big stone wall, and so you heat the entire place with a massive heat bank. Have it face sunlight in the winter)
The 11 people thing comes from a long standing community (40 + years) that's what they have seen work... more gets stupid, less is better tho.
I've lived with 9 people in a loft before and we shared one bathroom... that was fun!
At some point we were 27 people trying to build a life together and the property we had lined up fell through... after that it was impossible to find a new one, as we tried to run things in a unanimous consent type of governance. So it eventually fell apart and we went off to do our own thing.
Dreams and ideas change... the hardest part of building something like this is finding the right people
