# High-Performance 3D-Printed Walls Holcim And COBOD Deliver Its ViliaSprint² In France By Adam Harrie | Written with AI assistance | Published 2026-05-04 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/holcim-and-cobod References: [3dprinting](https://3dprinting.com/news/holcim-cobod-complete-europes-largest-residential-build-in-12-months/) [Holcim](https://www.trendhunter.com/trends/essential-homes) and [COBOD](https://www.trendhunter.com/trends/cobod) completed ViliaSprint², a three-storey, 12-unit social housing building in Bezannes, France, using on-site robotic concrete printing featuring Holcim’s TectorPrint mix. Plurial Novilia developed the 800-square-meter project, which used a COBOD gantry to deposit layered, fully load-bearing walls, with three operators managing the process via tablets. Holcim’s [Innovation Center](https://www.trendhunter.com/trends/crocs-the-roy-elephant) in Lyon formulated the concrete mix with synthetic macro-fibers to replace traditional reinforcement, achieving a 30% CO₂ reduction versus equivalent standard concrete and meeting France’s RE2020 2025 threshold. HOBO Architecture specified rounded forms that cut concrete use by about 10%, and wall printing finished in three months—twice as fast as a comparable conventional build on the same site. For residents and builders, the project demonstrates faster delivery, lower embodied carbon and reduced on-site labor intensity, moving construction toward advanced manufacturing on site. Holcim and COBOD plan larger developments next, signaling a path for 3D printing to scale in social housing and sustainable construction.
