This is really intressting, as it includes:
- the future tenent to actually design the home and helps built it
- local manfuactruing of parts of the home as prefab elements
- community land trust to make sure the house remains a low cost rental option
Obviously it is not perfect, but it is imho a pretty good idea and shows what is possible. Obviously other construction techniques might be used and the way they got the land is rather UK specific, but I believe something similar is possible in a lot of different places and it supports the weakest by providing some cheap good shelter.
