Colorado couple Christopher Smith and Merete Mueller began building their home back in 2011 and documented the journey in a new movie called "TINY: A Story About Living Small."

The house has a small galley kitchen, a bathroom, and a sleeping loft nestled between the floor and the 11-foot-high ceilings. For storage, the couple makes use of a small closet and two built-in bookshelves, and works from a built-in desk a reclaimed hardwood table.
