Design for nine-square-feet house

Michael Jantzen designed a house (using Google SketchUp) with nine-square feet of floor space. It has room for a lavatory, sink, heater, bed, chair, fold-down table, and storage. Where does the bed go? In the loft, which is part of the overhanging porch.

"I came up with the size by asking myself how what the absolute minimum amount of space would be needed for someone to live. I did a quick calculation in my head of the amount of space I took up while laying down and came up with nine square feet."
