A fun question! This is what I would do:
I'd get some land which was in a rural area and had fresh running water and natural space around it, like trees and hills. I'd build an Earthship, or some similarly whacky off-grid eco-construction which produced it's own electricity, managed its own water supply etc (see example images below). I'd grow fruit and vegetables. I'd have dogs, cats, chickens - not to eat, just to have for company. The house and grounds would be open to all who wanted to visit. Bonfires, hammocks, clear skies. Blissful self-sufficiency!
This could be anywhere in the world of course, but is currently only in my head :D.
This!!!!
Building an Earthship on a piece of cheap land is also my absolute dream. I dont understand how this housing model isn't already the mainstream way since it's just so much more superior than square brick houses.
An earthship is the closest modern home you can get from a Hobbit Hole. And who doesnt want to live in a Hobbit Hole with Solar power and natural air conditioning.
Narrow commercial interests I guess :) .......and yes, how truly wonderful such a natural Hobbit Hole would be to live in!
