Coastal communities are running out of real estate. Sea level rise threatens coastal communities with increased floods, erosion and displacement. To put it in perspective, the amount of water held in Greenland's ice sheet could fill the lower 48 "like a bathtub".
But an innovator in Thailand is figuring out how to build homes that rise above waters when they rise. Chutayaves Sinthuphan's Amphibious House can be placed on land and rises on stilts when there is a flood. But there is a much cheaper option--raft houses--which sit on water.
