The Tumbleweed Tiny House Company sells minuscule dwellings with themed appearances starting from $20,000. Each house can be made with integral wheels which beats the traditional caravan in my book! Not only are the houses as cute as, they are also environmentally friendly, have a small footprint and (as they are so small) often don't need planning permission. Interstingly, Small Houses are part of a growing movement towards a more modest way of life. When I win the lottery (and have a country estate) I shall build tiny houses in the grounds for my guests.
