Two 102 sq m homes in Buena Vista, Colorado, were built using A1-rated 3D printed concrete walls that provided the highest level of fire resistance and did not fuel combustion at any stage. This marked a significant step forward in fire-safe construction, particularly in a state where nearly half the population lived in wildfire-prone regions.
The project showcased the advantages of COBOD’s open-source 3D printing technology, which allowed real concrete to be used and material mixes to be customised for local conditions. This adaptability made the structures more resilient to wildfires, seismic activity and extreme temperature fluctuations.
The superstructure of one home was completed in just 16 days, highlighting the remarkable speed and efficiency of automated 3D construction.
The printer followed a precise, predefined path, reducing manual labour and ensuring consistent quality. This rapid process saved weeks of traditional construction time and improved overall project cost efficiency. Known as the VeroVistas, the two homes demonstrated 3D printing’s flexibility in design, one retained the distinctive layered concrete aesthetic, while the other adopted a traditional stucco finish.
“In an era of fast housing, VeroTouch is creating legacy homes that can be passed down, rather than torn down,” said Grant Hamel, VeroTouch’s Chief Executive Officer. “Beyond merely great design, we’re proud that VeroVistas homes offer a level of resilience to natural disasters like wildfires unmatched by any other product in this region. Because of that, we expect these homes to be standing strong 100 years from now.”
Priced at about $625,000 (which is comparable to average homes in Colorado’s mountain communities) the 3D printed houses offered modern design, superior fire resilience and market competitiveness. VeroTouch collaborated with local contractors, supporting regional employment and introducing cutting-edge building methods. The company received support from Colorado’s Innovative Housing Incentive Program (IHIP), which aimed to facilitate construction of 7,500 homes within three years.
Governor Jared Polis stated, “We are proud to accelerate innovation in housing to better address Colorado’s housing needs. The unveiling of these 3D printed homes is a great example of how we can support new building methods to create more housing now.”
Following the project’s success, VeroTouch began work on a 32-home community in Salida, expanding its workforce to meet rising demand. “3D construction printing provides a safer, more efficient, and sustainable way to build,” said Philip Lund-Nielsen, Co-founder and Head of Americas at COBOD International. “Colorado investing in broader application of 3D construction printing shows that this scalable method can help address the housing crisis, not only in Colorado, but across the U.S.”
