Oh hey look it's us.
That is pretty nice. I am not sure 400 SqFt would appease me, but I think 6-800 might.
So, this is actually pretty close to the Communist ideal communities that the USSR was working on many years ago. There would be personal space for families to have their "own" house, and every community had a large dining-hall/common area. It's a really neat idea, and I could see it working in small deployments like this.
When I saw this title I thought someone necro'd a thread about the new ICHQ.
I'd love to do this... except I can't stand other people. So, make mine 1 house and 3 dog houses I guess.
