Holcim and 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 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.
