Here is a website with photos, descriptions, and features of a low-impact woodland home. It looks like a hobbit burrow except the door is not round. This home was built by an ordinary person, with help from some friends. It used mostly local materials. It is cozy, safe, and beautiful -- the kind of place where many people would enjoy living -- but it cost less than building or buying a conventional house. This is a very good example for sustainable building and green living.
