I wouldn't choose the interior colors in this house, and I think its a bit too cluttered, but I like what he fit into the small size. Seeing what's in there made me feel it was much bigger than 13.1 ㎡. The builder said it was inspired by the Earthship idea. I’m not sure what that meant in this case. He built the tiny house on his own property to live in while renting out the main house. That makes sense to me as I would like to do that myself. There is a spot in our garden that I think would work well, but it would mean tearing down our storage house that is there now and there insn’t really anything wrong with it. 🙂 The outside looked better than the inside, I thought. Cleaner and nice materials.
