I came across these Japanese Dome Houses today while surfing the net. They’re built from polystyrene, "the fourth-generation building material" after wood, iron, and concrete. Basically a type of styrofoam. The special expanded polystyrene is said to have multiple environmental and health benefits including “prevention of aging and the recuperation of your health. ”
Sign me up! Screw the fountain of youth, I need one of these Dome Homes.
