Kim a reader of the Tiny House Blog discovered this video and I think it is a perfect example of what can be done with a little hard work and enginutity. I am not familiar with the language in the video, but I’m sure it is European.
This person took an old run down caravan or trailer and used it for the base, he then rebuilt it using his design and creating a simple structure for himself. It has all the basics, a place to sleep, cook and stay warm. Maybe this video is just the inspiration you need to start your own project.
