I recently bought a tiny house since there isn't much space in my city for a big house!
Oh that's cool! It's a whole movement. It advocates living simply in small homes but you know that
I agree, its a movement so save space and protect the environment. 
There currently no set definition as to what size a tiny house is. 
Yea I bet it varies from place to place. What else do you about tiny houses?
Tiny houses on wheels got popular when Jay Shafer designed and lived in his 96sq ft house in 2012
That makes sense, but I certainly couldnt live in a house that small! 
Early pioneers, Lloyd Kahn and Lester Walker since the 70s have tried to get the trend to catch but it didn't work until recently.
Yea nowadays people are a lot more conscious about the environment than they were before.
Until this trend started from 1978 to 2013 homes were being built bigger even though family sizes were decreasing.
