The tiny house movement refers to people who are willingly moving into smaller places to save money.
I have seen those on television, I'm not sure I could be part of that movement myself.
Yes many people love their space.  The average size of a home in America grew from 1978 to 2007 despite the family size decreasing.
I totally want more space! hahah My house is small for a family of three I think.
Although there is no clear definition to define tiny house it is generally accepted to be an undersized residential structure.
Undersized is definitely a word I would use to describe them!
The recent movement towards tiny homes is credited to Sarah Susanka.
I've honestly never heard of her.
