Welcome!
This sounds fantastic. You would be surprised how much land is available for affordable or free, to buy or lease. This is definitely a good place to start looking.
I have no money, I have no land, and no resources. But I have a dream.
Best starting place ever!
Money, land, and resources come later. Start with a library card and building skills. Hands on, practical skills have the highest trade value. Most of which can be learned for free or very little cash if you don't mind spending a bit of time getting to know your local library.
For example, in our town, our local library runs a
seed library with free
gardening and seed saving work shops. Knowing how to grow food and more importantly, breed them to thrive in your conditions (which is basically all seed saving is), then you've got a skill that 95% of the population lack. An allotment garden, or maybe a friend's back
yard takes very little effort to get going, so learning to improve the soil with what's on hand. Practice growing grains on a small scale for beer making... the possibilities are endless.
Or if seeds aren't your thing. Maybe another skill is where your passion lies?
Cob construction? Any of the list you mention.
Once you start gathering skills and get good at a few of them, people flock to you with offers of land and resources.
Another source of skill training is the Society for Creative Anachronism (SCA). BC is in the
SCA kingdom of An Tir. These people love building things, cooking, bard events. Everything on your list, they practice. And they are so generous with their knowledge. Not to mention they know how to have fun. Home brew mead from their own home grown
honey on a bard night. Heaven.
I would love to live in a community like you describe. Not in a place of my life to do so at the moment, but I'm gathering the skills necessary to be an invaluable contributor. Cooking, farming, livestock, and textiles are my skills. I started with sourcing my materials free from local farmers and a small allotment in town. As I got better at what I do, more possibilities opened up to me. Now I steward 5 acres and grow a good chunk of my food and practice experimental farming. I'm learning ways to grow food in our climate without outside inputs or
irrigation - a lot of things are different than they say in
books, so experimenting is a vital part to it. Just about every success in growing things, I learned from this forum. You're in the right place.
