The world needs more homes, fast: America alone is facing a deficit of about 4 million housing units. House Zero is a 2,400 square foot, 3-bedroom solution 3D-printed by a 9,500-pound robot. Designed by architecture firm Lake|Flato and construction tech startup ICON, House Zero’s airtight wall system is made of proprietary Lavacrete (a high-strength concrete), which can be printed in 10 days and improves energy efficiency while reducing material costs, waste, and build time. Drawing on House Zero’s design and in partnership with homebuilding giant Lennar, ICON this year broke ground on the country’s largest 3D-printed community, a 100-home project in Austin.
