PERI 3D Construction completes Europe's largest 3D printed apartment building, ViliaSprint², in France

PERI 3D Construction has completed ViliaSprint² in Bezannes, France, a three-story residential building delivering 12 social housing apartments across 800 m² of living space. Developed by social housing provider Plurial Novilia, the project used a COBOD BOD2 gantry printer to extrude concrete supplied by Holcim through its TectorPrint technology, reinforced with synthetic macro fibres and formulated within the CO₂-reduced ECOPact range. Printing began in March 2025 and finished ahead of schedule, with the shell completed in 34 effective printing days versus 50 originally planned. The project team reported that shell construction time was cut in half compared with a near-identical conventionally built structure on the same site, requiring three site operators instead of six, and reducing waste from 10% to 5%.

This project represents a rare instance of 3D construction printing moving beyond single-family homes and demonstration walls into multi-family residential production at scale. The 800 m² footprint and 12-unit density place ViliaSprint² well above typical 3DCP projects, which have historically struggled to exceed 200–300 m² in Europe. The use of curved façades and a rounded floor plan without formwork cost premiums, combined with a 10% reduction in concrete volume through optimized geometry, demonstrates that design freedom can translate into material savings when the printing process is integrated from the start. The project also illustrates the growing role of social housing providers as early adopters of 3DCP, since their focus on cost and schedule predictability aligns well with the technology's current strengths in reducing labor and waste. However, the technology remains limited to shell construction — interior fit-out, MEP, and finishing still follow conventional methods, which constrains the total time savings to roughly 15–20% of overall project duration.

For PERI 3D Construction and COBOD, ViliaSprint² provides a credible reference for multi-story residential projects that can be cited in future bids across Europe. The key next step is demonstrating that the 34-day shell timeline can be replicated on a second project without the bespoke optimization that characterized this first build. For the broader 3DCP industry, the project confirms that the technology can compete on schedule and labor for social housing, but the absence of integrated MEP or finishing solutions means the value proposition remains partial. Buyers should evaluate 3DCP projects on total project duration and cost, not just shell metrics.
