In the Danish village of Holstebro, Europe’s largest 3D-printed housing community has been completed. Designed by SAGA Space Architects, Skovsporet—Danish for “forest track”—provides student housing built using low-carbon concrete and COBOD’s BOD3 mobile construction printer, developed for residential projects. The automated construction process demonstrates how 3D printing can accelerate housing delivery, while innovative low-carbon materials can help reduce the environmental impact of construction.
“Skovsporet explores what happens when 3D printing moves beyond the prototype and becomes a method for building homes at scale. By translating the digital model directly into full-sized structural elements, the technology brings design and construction closer to the ambition of changing the construction industry.”

Masterplan
Located near VIA University College’s Holstebro campus, the Skovsporet student village spans 1650 square metres and consists of 36 apartments divided into six clusters of six apartments. The apartments, which range in size from 40 to 60 square metres, each feature a full kitchen, study area, lounge, bathroom and bedroom—a spacious upgrade from what many might recall of more traditional student dormitories.
Interior
Inside, the apartments are completed with coated plywood panels that integrate storage and shelving directly into the architecture and contrast directly with the exposed printed concrete walls. Large-scale glazed windows frame views to the shared garden space, and together with elongated skylights, bring natural light deep into the apartments. Acoustic panels in cork improve the audible comfort of the spaces, while keeping the compact interiors inviting and materially warm.
Intention
The student village has been designed to create varying levels of privacy through a layering of private and public space. Residents can withdraw to their own apartment, sit outside with their nearby neighbours, or spend time in the landscaped shared spaces that connect the different apartment clusters. Conscious of the landscape, the design retains 90% of the mature trees that existed on site.
Construction
The project was 3D printed using a mobile construction printer specifically designed for residential projects. Printed directly on site, the structural walls were built up in layers to form straight and curved surfaces, corners, and openings. By applying the material layer by layer, this system only places material where it is needed—reducing the material waste often seen in traditional formwork. The printed concrete walls work together with timber roof structures to demonstrate an effective hybrid building approach.
Materials
The main printed structures use D.fab concrete containing FUTURECEM, a low-carbon cement. The material innovation is extended to the bicycle shed, where cement-free printed elements using MEVOcem were introduced. These elements contain no cement and achieve an 84 percent reduction in CO₂ emissions compared with traditional concrete.
Learnings
Skovsporet was completed within the regulatory and financial framework of subsidized housing in Denmark, thus the 3D-printed construction was required to meet the same demands as conventional permanent housing. As the architects explain, “Successfully delivering 36 homes within these constraints demonstrates that 3D printing can operate within the practical and economic realities of housing at scale.”
