@Oliver Schick I think I know what you mean, and I see why, lets say one owner/building society/group per small plot would be nice.
On plots like Dragonerarealthey do a lot of participative stuff before anything starts, and while that is great, it seems to be awfully complicated and somehow not necessarily successful, just because the resources aren't there.
But at least this plot wasn't just sold to the big Austrian investor, so there is that as a success.
So maybe just going with plots big enough for a lets say 10 apartments house so you get a mix of all the ideas and goals would be great. Is this what you're getting at?
