Hi Alice,
I'll watch this thread and get in touch if we find anything. We are looking for land to build an off-grid house (pretty much given up on the UK due to the cost) and are searching in Portugal/Italy. There is a possibility in Sarzana, Liguria but we we waiting for a planning decision! We're looking in areas close to wilderness rather than in farmland but near to a school and community. We'd welcome people living on it and helping to cultivate it.
Stay in touch!
