Holcim and COBOD have completed ViliaSprint², a three-storey social housing project in Bezannes, France. The building uses robotic concrete printing and a specialized TectorPrint mix to create load-bearing walls, significantly reducing on-site labor and construction timelines. The project achieved a 30% reduction in CO2 emissions compared to standard concrete by using synthetic macro-fibers instead of traditional reinforcement. Optimized rounded designs further cut material use by 10%, demonstrating a scalable path for reducing embodied carbon in multi-unit residential construction.
