The Casitas at The Halles by Hive 3D and Eco Material Technologies are a new project to create sustainable, 3D-printed homes for vacation rentals near Austin, Texas. These unique low-profile homes use a technology that creates 92% less emissions than traditional concrete. Round Top, Texas, 80 miles east of Austin, will now be home to the world’s first near zero-carbon, 3D-printed neighborhood. Eco Material Technologies, a producer of sustainable cement alternatives, and Hive 3D, an automated construction company, worked together to build five vacation rentals, all of which have been 3D printed with an Eco Material cement mixture called PozzoCEM Vite.
