This started out as a project to build a tiny house on wheels that Austin Hay could take away to college. And it’s pretty comfortable, too, considering that it has three-sided bay windows around his desk and hot water on demand.
Austin used materials from the salvage yard and from his own bedroom and managed to come up with only three trash cans of waste. Still, the whole thing cost him pretty much in my opinion: about 12.000$.
He’s also planning to build a solar cart to generate electricity. Here is a short documentary of Austin’s house on wheels.
