The living room couch of this tiny home folds out to a queen-size bed. There is a stairway that goes up to the bedroom loft. Every step is a drawer or cabinet. There is an electric fireplace under the stairs to keep the house warm.
The closet in bathroom can be a space for washer/dryer, and there is even a jacuzzi tub/shower.
For more details, the builder/designer Chris Heininge has a website.
