Entered into Architecture for Humanity's relief housing competition, FutureShack addresses the shelter needs of refugees and homeless persons around the world.

Maintained by solar power, FutureShack is ready for occupancy within twenty-four hours.
An example can be viewed at The Cooper Hewitt until October, 2004.
