I found this pretty neat house that is designed to be a post disaster shelter, but has the potential to be so much more. It is one of the most aesthetically pleasing post disaster houses and can be setup in 6 hours with 5 people. The house is designed to shelter 5 people in a short term situation. Below is a video of the construction. I could image the addition of a metal roof and some better siding would make this a much more permeate house for 1-2 people.
