Back when I was in high school I found a book at the library which really captured my imagination, and I brought it home several different times. It was Rolling Homes: Handmade Houses on Wheels, by Jane Lidz. For a long time I wanted this book, and kept an eye on the copy that was for sale on Amazon for $74. It's since come down in price, but when I found it for $25 at Powell's, I grabbed it. So naturally I'm a huge fan of the Tiny House Movement and have been keeping an eye on that as well.
I'm also a huge fan of Ana White. Ana makes furniture with her husband, and they put the plans out for everything they make on her site, www.ana-white.com for free. If you're in the least (and I do mean least) bit handy and need a piece of furniture you ought to look for it in her many designs, because there are a lot and they look pretty easy to put together. Lately, she and her husband have turned their collective hand to making tiny houses.
This house is not the fanciest or the most high-end finished I've seen, but it does incorporate a lot of really clever ideas I haven't seen anywhere else. I especially like the elevator bed and have thought this a good way to get a bed in a small space without having to climb up stairs or a ladder (think: age in place), but my idea for getting it up and down was a lot more primitive. Using a garage door opener to get the job done was pretty ingenious. There are other smart ideas as well. Enjoy!
