In France, ViliaSprint² is born, the largest 3D printed residential building in Europe

In France, ViliaSprint² has been completed, which is considered the largest 3D printed residential building in Europe. The project, carried out by the developer Plurial Novilia in collaboration with HOBO Architecture and PERI 3D Construction, represents a significant advancement in the field of innovative and sustainable construction.

The building houses 12 social housing apartments spread over three floors and is especially notable for the speed with which it was constructed. The printing phase of the structure was completed in just 34 days, much less than the initially planned 50. By comparison, a very similar building located next to it and constructed using traditional techniques took about three months longer.

A COBOD BOD2 printer was used for the project, which has already been employed in other innovative projects such as earthquake-resistant homes and 3D printed data centers. According to COBOD, ViliaSprint² is the first building in France where both the load-bearing structure and all walls were printed on-site. The printer extruded layers of cementitious material provided by Holcim, while three operators supervised the entire process.

ViliaSprint² and further details about the 3D printed building Traditional work, such as roof installation, windows, electrical systems, and finishes, began in March 2025 and concluded in the early months of 2026. The building offers about 800 square meters of living space, and each apartment has its own private balcony.

One of the most interesting aspects concerns the design. The curved facade and rounded structure would have been significantly more expensive using traditional techniques, while 3D printing allowed for their realization without significant additional costs. Moreover, the project has allowed for a 10% reduction in cement consumption thanks to the optimization of shapes.

From an energy perspective, ViliaSprint² integrates perlite insulation, wooden balconies, 500 square meters of photovoltaic panels, and a hybrid system with heat pump and gas. All this enables the building to achieve about 60% energy self-sufficiency, in line with French environmental standards RE2020 2025. Looking to the future, Plurial Novilia and its partners are already planning an even larger project with about 40 apartments and the simultaneous use of two 3D printers.
