Plurial Novilia, a subsidiary of the French Action Logement Group and Peri 3D Construction, a leading provider of 3D printing solutions, announce the start of construction of a joint project: Viliasprint²-a construction project of a three-storey residential building with 12 social housing in France, France. The walls of the facade and the interior are printed directly on the construction site using a large-format 3D portal printer. The pressure over three floors started a few weeks ago and is said to be complete by June 2025, the completion of the overall project is planned for the first quarter of 2026.
The construction of the 3D building pressure not only shortens the construction period, but also improves working conditions on the construction site. As the first printed house of France, Viliasprint² also reaches the status of the largest 3D printed apartment building across Europe and is also the first project of this size, in which the loads are completely carried through the 3D printed structures.
The largest 3D printed residential building in Europe
Plurial Novilia is not a newcomer to the field – the developer presented five houses with 3D printed walls in 2022. With Viliasprint², which was presented in September 2022 and designed by the architecture firm Hobo Architecture, you want to reach new milestones in 3D building pressure.
With an average width of 10 meters, a length of 30 meters and a height of 9 meters, the building becomes the largest 3D printed house in Europe. Each floor comprises a gross area of 300 m², which results in a total of 800 m² living space for the 12 apartments.
Viliasprint² uses a continuous 3D concrete pressure structure for all walls of the project – an innovative approach in the international large -scale building system.
In order to prove the advantages of the 3D concrete pressure in practice, an identical building is built on the same property in traditional construction. It will not only create additional living space, but also enable the comparison between the two construction methods in relation to the construction phase and the later use.
The preparatory work lasted from September 2024 to March 2025 and included infrastructure measures and the construction of the ceiling above the basement. The pressure phase that starts now will take less than three months – at a maximum of four weeks of printing time per floor. This reduces the construction of the load -bearing structure by two months compared to conventional procedures.
In use: the complete solution for 3D printing from Peri 3D Construction
As one of the leading companies in the 3D building pressure, Peri 3D Construction has its own complete solution for 3D concrete printing. A large-format 3D portal printer COBOD BOD2 with a width of 12 meters and 11 meters is built around the pressure area. The print head moves automatically via the building ground area and lays concrete layers: Each wall consists of an 8 cm thick outer and 16 cm double inner layer. The 20 cm wide space is filled with a permanent insulation material. Glass fiber connectors connect the layers and stiffen the structure. A special milestone of this project: The 3D printed walls are 100% load-bearing-a real premiere in a 3D building pressure, especially for a project of this size. This step illustrates the quick further development of the construction of the 3D concrete pressure and opens up new potential in the savings of materials.
Peri 3D Construction will implement two more 3D printing projects in Germany this year. Among other things, the company will prove in one of these projects that 3D printing can already be created inexpensive living space than with conventional construction methods.
Special concrete with a low CO2 balance
Holcim developed a printable high-performance concrete based on the modified tectorprint recipe for this project. This is real concrete – no mortar – the strength class C40/50 – XF1 – XC0, reinforced with macro and microfibers. These ensure particularly good structural properties and high fire resistance.
The concrete belongs to the ECOPACT product line of Holcim, which has at least 30 % fewer CO2 emissions compared to conventional concrete. It is based on the CO2-reduced Ecoplanet cement and is made directly on the construction site from a pre-mix with locally obtained sand and rock granbs (from the Groupe Moroni)-to further reduce environmental pollution.
Encounter the challenges of the construction industry with innovation
The construction site is looked after by Demathieu Bard Construction. Their local teams were trained in the 3D construction by Peri 3D Construction, which also takes over the overall coordination. In addition to the shortened construction period, waste quantities and noise pollution for residents should also be reduced.
The construction process also significantly improves the working conditions of the craftsmen because severe loads are avoided and accident risks are reduced.
Viliasprint² also relies on innovative organic and geoba-based materials such as Perlit (first driven out of Knauf in France) and wood (used for the load-bearing structure of the balcony). Thanks to its compact shape and the round corners made possible by digital tools, the concrete consumption is reduced by an estimated 10 %.
In addition to 500 m² photovoltaic systems, a central heat pump is used, which provides hot water and heating. Sun level analyzes under the direction of Prof. Timo Leukefeld, a German expert for energy autonomy, led to the optimized orientation of the building and enable a desired energy self -sufficient of 60 %.
Thanks to these measures, the project achieves an optimized CO2 footprint and fulfills the RE2020 targets for 2025.
With the project, Plurial Novilia would like to demonstrate the feasibility of the construction process and make the step from the experimental construction to the series tire. In the future, the industrialization of 3D printing should enable more apartments faster and at controlled costs. Viliasprint² should serve as a reference project for similar projects across France.
