Europe's largest 3D-printed residential building has been constructed in France
Construction has been completed in France on Europe’s largest 3D-printed residential building. Construction began in March 2025 and took 34 working days. The project has become one of the largest examples of the use of 3D construction technologies in Europe’s residential sector.
In the Bezannes district of the French city of Reims, France’s first social housing building constructed using 3D printing directly on the construction site was unveiled. The ViliaSprint2 project belongs to the social housing development company Plurial Novilia and is currently considered the largest residential building in Europe to be printed using 3D printing.
The building has three floors, 12 apartments, and covers an area of approximately 800 square meters.
As noted by representatives of PERI 3D Construction, this experience will help accelerate construction speeds and reduce costs for similar projects in the future.
It is noted that the material used was developed by Holcim and features a special type of concrete designed for 3D printing. The composition includes synthetic microfibers that partially replace traditional rebar.
The concrete is part of a range of low-carbon materials, and the manufacturer says its carbon footprint is at least 30% smaller than that of conventional concrete.
Compared to many similar projects that use special solutions that are easier to print, the developers opted for full-strength concrete with aggregates up to 8 millimeters in size, which is considered more advantageous from both an economic and environmental standpoint.
It is known that the printing process began in March 2025 and was completed in just 34 working days, significantly less than the initial estimate of 50 days.
“The reduction in time was made possible by optimizing the installation of precast slabs and minimizing the number of printer repositionings on the construction site. Overall, the entire project was completed in approximately 12 months,” the article noted.
The developer says that the technology not only reduces construction time but also helps improve working conditions for crews on the construction site.
At the same time, to assess the real benefits of this technology, Plurial Novilia built a second, nearly identical house on the same site using traditional construction methods.
“A comparison of the two construction sites revealed significant differences. Only three operators were needed to print the structure, whereas six workers were required for traditional construction. The printer operators controlled the entire process from tablets, without handling heavy materials. At the same time, a small team was busy assembling reinforced concrete columns and structural elements that could not be printed,” the publication added.
