I've always been very interested in this kind of housing. To be honest, I have the feeling I will build myself a house like this one day. I can probably find a small patch of land at a reasonable price about an hour driving and take a small loan to build it. I lived in a 12 square meter studio for 3 years, this seems heaven in contrast to that. Mix it with solar panels and you have a very nice place to call home...
I think it would be even more fun to get a big farm/orchard/ranch with an old farmhouse, sheds, etc., and then bring in high speed fiber, cheap/sustainable utilities, and then put a bunch of 200-1200 square foot cabins in the less-productive, more-scenic parts of the property. Walkable community, private housing, cheap, and then big common areas for workspaces.
