Have you heard of the tiny house movement?
I'm not sure, what exactly is it?
It is basically a movement that advocates living in small homes.
Oh okay, I think I've seen shows where people move into tiny homes. I'm not sure I could do that.
There is no set definition of what a tiny house is.
Well I guess that is true, but I've seen some that were so small, you wouldn't have much room to walk around
This movement is needed due to average size of a single family home growing  from 1978 to in 2007.
What are the sizes of these tiny homes?
