I really loved this article on folding bamboo houses, designed for use after a natural (or not) disaster. What I liked was the sense of the potential different uses of the space under the shelter through the change in its geometry. By opening and closing the shape you could create open spaces, or discrete ones.
“Ming Tang’s beautiful origami-inspired Folded Bamboo Houses are intended to be used as temporary shelters in the aftermath of an earthquake. Brilliant in their simplicity, the geometric shelters are constructed from renewable materials and can be folded into a variety of structurally sound shapes.”
