Germany's first social housing units are constructed from 3D-printed concrete in Lünen.
3D printing technology enables a fast and cost-effective construction method.
The project provides an innovative solution for affordable housing and shows significant potential for the construction industry.
Pioneering Spirit in the Construction Crisis: Social Housing from 3D-Printed Concrete.
While the construction industry grapples with soaring material costs, rising interest rates, and a shortage of skilled labor, a groundbreaking project in the Ruhr region is scripting a success story. Thanks to 3D printing technology, the first social housing units in Germany are taking shape from concrete. Despite the ongoing construction crisis and the scarcity of affordable housing, these innovative projects offer hope and opportunities for the sector.
3D printing technology allows the creation of walls for the ground and upper floors in approximately 100 hours of pure printing time—faster and more efficient than on traditional construction sites. The six-unit apartment building is expected to be move-in ready within 14 to 16 months, with construction costs of 1.9 million euros.
North Rhine-Westphalia's Minister of Building, Ina Scharrenbach, praises not only the time saved but also the low carbon footprint and recyclability of the "high-tech cement" used. This project has the potential to be a pioneering solution to the housing demand.
The state has provided substantial funds from public support programs for construction to make living in the innovative multi-family building accessible to those on a budget. In return, rents are capped at a maximum of 6 euros per square meter and reserved for those with low incomes.
This project is a message to the construction industry, which requires innovation as an answer to current challenges. 3D printing could be the key to meeting the housing demand. This project not only offers an innovative construction method but also valuable practical knowledge for future construction projects.
