Tiny Liveable Houses

These houses have a tiny "footprint" but are beautiful and use space very efficiently. Energy use and maintenance is correspondingly tiny. Some people put them in their back yard as a retreat. Some use them as guest houses. Others actually live in them full time. Cool idea. You could probably put a dome over them and create an artificial environment. It only takes 5 minutes to heat the whole house up, and energy costs are between $20 and $50 per month. I can imagine installing solar panels and going completely off grid.
