France 3D Prints 12-Unit Apartment Building in 34 Days

Imagine a robot building an entire apartment building while you sleep, layer by layer, completing in just over a month what normally takes half a year.

That's exactly what happened in France, where ViliaSprint² just became Europe's largest 3D-printed apartment building. The three-story structure houses 12 affordable apartments, each with its own balcony, across 8,611 square feet of living space.

Developer Plurial Novilia used a COBOD BOD2 printer that squeezed out concrete like frosting, building the walls and structure in just 34 days. Three human operators monitored the machine as it worked. The entire project, including traditional finishing work like roofing and wiring, wrapped up three months faster than an identical building constructed next door using conventional methods.

The speed isn't the only advantage. The curved design would cost significantly more using traditional construction, but the 3D printer created those complex shapes at no extra cost. The optimized shape also used 10% less concrete than standard building methods.

The building isn't just fast. It's green. Developers installed 5,400 square feet of solar panels and a hybrid heating system that makes the building 60% energy self-sufficient, meeting France's strict 2025 environmental standards.

Why This Inspires

This project proves that cutting-edge technology can solve one of society's most pressing problems: affordable housing. While cities worldwide struggle with housing shortages and rising costs, 3D printing offers a faster, cheaper path forward.

The concrete mixture was produced on-site, reducing transportation emissions. The precision of robotic construction minimized material waste. And the speed means families can move into safe, modern homes months earlier than traditional construction allows.

The team is already planning their next project with 40 apartments using two printers working simultaneously. Their goal? Cut printing time by 75% and match the cost of conventional construction while maintaining quality.

What started as an experiment is becoming a blueprint for the future. When technology designed for speed also delivers sustainability, accessibility, and beauty, everyone wins.
