Sweet Relief: The QuaDror disaster-relief house frame reduces the system’s interlocking module to four so-called universal joints and eight corner pieces (for stiffening and stability) that are attached to a locally sourced material (even bamboo) to form eight support beams. The structure can then be skinned in anything that’s available. "In one 40-foot container we can ship 1,300 kits—that’s 1,300 dwellings," says Benshetrit. Best of all: The house needn’t be temporary. "It gives people something that can be moved, re-skinned, and improved—a real home."
