Extreme Homes: Jigsaw, Bubble, Spires

This amazing assortment of homes from all over the world includes a Californian home modelled on a spy plane, a Japanese origami-style residence in Northern Ireland, a glass house with no internal walls in The Netherlands and a medieval-inspired new-build in Idaho. Mexico has a whole series of crazily-colored bubble homes, there's a wooden lodge in Denmark that's like a giant jigsaw puzzle and weird spires sticking out of a hillside create a home in Italy. An Australian home got bigger by shrinking, a house in California has been designed to withstand falling trees while one in South Korea has a striped skin and a French chalet takes after-ski luxury to a new level.
