ICON builds 3D-printed houses from disaster-proof concrete in Texas

Developer 3Strands and construction technology company ICON have built four 3D-printed houses in Austin, Texas, from concrete that's designed to cope with extreme weather.

Named East 17th Street Residences, the houses are made from ICON's Portland cement-based material Lavacrete.

It took five to seven days to print each house. ICON claims that The Vulcan can print Lavacrete more accurately and at a higher speed than manual labour so that the houses are cost-effective and well-built.

Situated in the East Austin neighbourhood, each house has large North-facing windows with vaulted master bedrooms and open floor plans.
