Single-family house in Beckum, 2020
The first 3D-printed residential building in Germany not only marks our debut in the implementation of approved residential buildings, but also a milestone in construction history.
In autumn 2020, we printed Germany's first residential building in Beckum, North Rhine-Westphalia. This project impressively demonstrated that the innovative 3D construction printing technology is market-ready for residential construction.
The construction technology, implemented for the first time in Germany, has undergone all official approval procedures in recent months. The two-story single-family home offers approximately 80 square meters per floor. The house's unusual shape with rounded walls is immediately striking. The unique design, which would have been impossible to realize with conventional construction methods, was realized cost-effectively and time-efficiently using the BOD2.

IMPRESSIONS OF THE PROJECT IMPLEMENTATION
Germany's first 3D-printed building is being built
A pilot project takes off
The BOD2 was assembled in Beckum in a very short time. The Z-axes were mounted on foundations that the printer had printed itself before construction began.
The future you can touch
During the construction of the first 3D-printed residential building, the BOD2 demonstrated its suitability for construction under real-world conditions. A sophisticated combination of double- and triple-layer walls ensures effective structural stability while simultaneously saving material.
You've never seen concrete like this before
Curves, overhangs, and parts of the interior design were integrated directly into the planning and effortlessly realized by the printer. In this project, individual elements were also prefabricated and assembled on-site.
Perfectly formed
The completed residential building offers a glimpse into the design freedom enabled by 3D construction printing. The building was open to visitors as a model home for a year and is now occupied.

Requirements and solutions
Requirements
A major debut requires several challenges that the team faced during the course of the project: Obtaining a building permit for a 3D-printed residential building for the first time, the changing conditions on the construction site, and the high level of public attention are just a small selection of requirements for which solutions had to be found.
Solutions
The building permit was obtained in close cooperation with the Ministry of the State of North Rhine-Westphalia and the relevant authorities through a case-by-case approval. The authorities were very positive and open to the project and the new construction method, which made the coordination process quick and smooth. The building was constructed without reinforcement, as it easily achieved the required structural properties without reinforcement. Since experience in dealing with changing weather conditions was limited at the time – and the team wanted to protect themselves from prying eyes during their debut – a roofed enclosure was built around the printing area. This will no longer be required for new 3D printing projects.
Customer benefit
With the single-family home in Beckum, we and our project partners were able to demonstrate the potential of 3D building printing: fast execution times, a high degree of design freedom, and the ability to obtain approval for this innovative construction method, which also meets the high building regulations standards in Germany.
