Chilean artist Carolina Pino has designed what she calls a Shellhouse for the homeless.
The Shellhouse concept is a collapsible, triangular, orgami-like shelter made of cardboard. Thus, it provides a roof over one's head, but can be folded up and carried about during the day.
Included in the design are plans for building a radio transmitter so that owners can communicate with others about their current locations. This ability is essential for obtaining and maintaining employment.
Hmm. Parking lots for cars and bikes of various sorts. Maybe shelving for homes?
