American construction technology startup Icon has developed a method for building a single-storey house out of cement within 24 hours, with 3D printing. With its technology, the startup claimed it can produce an 800-square-foot house. The current cost of building the house is $10,000 (around ₹6,50,000), however, the startup plans to reduce the cost to $4,000 (about ₹2,60,000) per house.
