Tiny homes may be tiny, but the cost of the pre-designed plans to build them are not, as they can cost anywhere between $500 and $800 dollars. But, I found a website that offers 11 free tiny house plans that range from charming to squeal-worthy. To make it even better, there's no registration required, so we can download at will.
The first one of these plans I saw was a 2-story called The Forest-Rose, shown below. It still might be my favorite.
The 160sf, 1 and 1/2 story Rolling Bungalow is intended to be built on a trailer frame for complete portability. You could buy an RV, or you could be way cooler and build one of these bad boys.
Here are some great books available detailing more in-depth plans and ideas:
