Residents Lawrence Nourzad and Angela Hontas, who bought a printed home at the ranch earlier this summer, compared their new house to a “fortress”.
Mr Nourzad said the walls are solid enough to “go head-on with maybe an F2, F3 tornado and be pretty resilient”. They were praised for keeping the interior cool in the Texas heat, but criticised for causing connectivity problems.
Mr Nourzad said: “These are really strong, thick walls. That’s what provides a lot of value for us as homeowners. But signal doesn’t transfer through these walls very well.”
The walls are designed to be resistant to water, mould, termites and extreme weather.
While the walls are printed, the foundation and metal roof are installed through traditional construction methods.
For its next project, Icon has been contracted by Nasa to built shelters and landing pads that are suitable for the Moon’s surface.
