am I being thick, or does it seem to anyone else that the owner not paying for the materials shouldn't be the end?
get this community set up, then a plan to use the labour to generate a small income... this income can pay for materials. Just make sure it works for the community. don't sign up to any daft timescales aroun the renovation. you need to have a carpenter come and live with you for a bit, then a sparky, then a plasterer... etc etc. bit by bit, slowly slowly, and the longer the resto takes the better it is for the community I'd have thought.
Seems like a task a large one at that
