Tina Hovsepian, a 2009 graduate from the USC School of Architecture, has designed and developed a foldable, portable, emergency housing shelter based on the principles of origami. HerCardborigami shelter is constructed from recycled cardboard and expands into a shelter big enough for two people to sleep in. The cardboard origami shelter can then fold down small enough to carry or even be placed on bus bike racks for long distance transport.
