With its elegant structure and stark simplicity, the A-Frame is a cheap, easy home that you could build yourself if you really wanted to. The blueprints and instructions cost just $30. It was designed by Joe Everson, a tiny home entrepreneur in Tennessee.

The structure can also transform into a "closed" mode to protect from the elements. It reduces its size to 80 square feet.
