1 Hour Design Challenge: Emergency Shelters - This pop out shelter is simple, cost-effective and is easily mass-produced. My design combines a number of cheap materials to form a flexible waterproof building sheet that is folded as shown below. This design provides ten (or more) shelters in one assembly. Assembly is easy just pin down one end and then pull out the other end, once the expansion of the compartments is complete, secure last end to the ground via pins.
