Australia’s first 3D-printed two-storey house built in just 18 hours

Australia’s first fully 3D-printed two-storey concrete home has been completed in Tapping, Perth by Contec Australia, marking a significant advancement in construction technology. The structural walls of the house were printed on-site in just 18 hours using a high-strength concrete mix that is three times stronger than standard brick. This innovative material is cyclone-rated, fire-resistant, termite-proof, and thermally efficient. The entire build, including roofing, wiring, and interior finishes, took five months, combining rapid robotic construction for the shell with traditional craftsmanship for the finishing work. The house features modern, open-plan interiors with three bedrooms, two bathrooms, a garage, and a balcony, demonstrating that 3D-printed homes can be both stylish and livable. Large windows and sliding doors enhance natural light and indoor-outdoor flow. Importantly, Contec Australia reports that the project achieved a 22% cost saving compared to conventional masonry builds, due to faster wall construction, reduced material use,
