Everyone is surprised to find out that I live in a tiny house by preference. 
I have seen shows advertised about tiny homes, but I really do not know much about them
They are a return to a frugal way of living. The small house movement is what its called. Basically members of the movement are saying we don't need a big house, we don't need a big space or items to live our lives. Most also pair this with a love of travel and desire to be more in nature.
