I'm thinking of "published designs" for communities which detail the necessary and sufficient items required for "mostly" self-sustainability. The hope is to provide guidance for town planning. A return to local farms, animal labor, barter economics, cooperation, etc. would be the basis for a model. On the other hand we have a lot more refined materials readily available such as aluminum, copper, steel, etc. This used to be true historically.
