A quartet of houses designed by local firm Logan Architecture and built from 3D-printed concrete by construction tech company ICON has completed in Austin, Texas.
The East 17th Street Residences in East Austin are now on the market, which construction company ICON and developer 3strands claim is a first. "They are the first 3D-printed homes for sale in the US and ready for move-in," ICON told Dezeen.
The East 17th Street Residences development includes four homes of varying sizes and layouts
The four dwellings have ground-floor walls built using ICON's Vulcan construction system, which uses a robotic armature to layer Portland-cement-based material Lavacrete into striated surfaces.
ICON claims that this process creates a stronger and longer-lasting building material compared to traditional techniques, and makes the homes tougher in the face of extreme weather. Each of the houses has a ground floor built using an additive manufacturing technique
"3D-printing technology provides safer, more resilient homes that are designed to withstand fire, flood, wind and other natural disasters better than conventionally built homes," said the company.
The 3D-printed elements for the development, which comprises two two-bedroom homes and two four-bedroom homes, were completed in March 2021. It took five to seven days to print each house.
