Europe’s largest 3D-printed apartment building, ViliaSprint², has been successfully completed in France. This innovative structure consists of 12 social housing apartments across three floors and astonishingly took only 34 days to print.
Developed by Plurial Novilia, ViliaSprint² was designed by HOBO Architecture and printed using a COBOD BOD2 3D printer, which has also been used for other notable projects, including a 3D-printed data center and earthquake-resistant houses. Located next to a similarly designed building constructed with traditional methods, ViliaSprint²’s creation timeline was significantly shorter, completing three months faster than its conventional counterpart.
ViliaSprint² is notable as it marks the first instance in France where both the load-bearing structures and all walls were printed on-site. The printing utilized a cement-like material supplied by Holcim, and while the project initially projected a 50-day printing duration, it was completed in just 34 days under the watchful eye of a three-person team. Following the printing phase, traditional building tasks like installing the roof, windows, and wiring began in March 2025, culminating in early 2026.
According to the developers, the curved facade and rounded layout were made feasible through 3D printing, allowing for complex designs without incurring excessive costs associated with traditional construction methods. The project also prioritized sustainability, integrating perlite insulation, timber balcony structures, and 500 sq m of photovoltaic panels. Furthermore, a hybrid gas/heat pump system has been implemented, achieving around 60% energy self-sufficiency in line with France’s green building targets.
Each of the 12 apartments features its own balcony, contributing to a total of 800 sq m of living space across the building. While ViliaSprint² may hold the title of the largest 3D-printed apartment building in the world, future developments are already in the planning stages, including a project aiming to construct approximately 40 apartments concurrently using two 3D printers, which could drastically reduce print times.
