Material and time — Walls were printed in about 105 hours using Holcim's TectorPrint material.
- Division launch — Matthäi Schlüsselfertigbau has launched a construction 3D printing division after completing its Selsingen, Lower Saxony headquarters.
- Printed structure — The two-story building was produced with COBOD's BOD2 construction 3D printer, with PERI 3D Construction as technology partner and supervisor.
- Building data — The headquarters provides 364 m² of usable space, measures around 7.4 m high, 22.5 m long, and 13.5 m deep, with 170 m² on the ground floor and 194 m² on the first floor.
- Hybrid reality — Foundation, base slab, floors, and roof were built conventionally, while Schulenburg and Mense-Korte designed the form and facade.
From pilot project to in-house capability
Matthäi Schlüsselfertigbau has launched a construction 3D printing division, moving from a single printed building project to an internal business capability. The division was established after the completion of a new two-story headquarters in Selsingen, Lower Saxony, built using COBOD's BOD2 construction 3D printer.
The move matters because it ties the technology to an operating construction group rather than treating it as a one-off demonstration. Matthäi brings scale: over 3,300 employees and more than 1 billion EUR in revenue.
How the Selsingen building was produced
The headquarters provides 364 m² of usable space, with 170 m² on the ground floor and 194 m² on the first floor. The building measures around 7.4 m high, 22.5 m long, and 13.5 m deep.
PERI 3D Construction acted as the technology partner and supervisor during the printing phase. The walls of the building were printed in about 105 hours using Holcim's TectorPrint material. The foundation, base slab, floors, and roof were built using conventional methods, a reminder that construction 3D printing here was integrated into a hybrid build process rather than replacing every trade.
The building's form and facade were designed by the architectural office Schulenburg and planning firm Mense-Korte.
What the partners say
"The entire Matthäi Group is proud to be able to realise the first 3D-printed building in Northern Germany. Together with our partners at PERI 3D Construction, we are taking an important step into the future of construction. Once again, this shows how strongly Matthäi combines entrepreneurial growth with innovation and progress," said Bernd Mergard, Managing Director of Matthäi Schlüsselfertigbau.
"Matthäi printed a two-story office building and then set up its own printing division. That step, from one project to an in-house capability, is exactly what we want to see. It shows construction 3D printing has moved from demonstration into everyday business," added Philip Lund-Nielsen, Co-founder & CCO of COBOD International.
"3D concrete printing allows us to completely revolutionize traditional construction processes. As a company, we see in this innovation not only a technological advance, but the creation of an entirely new sector within construction. With this technology, we are shaping the future of building: faster, more flexible and more sustainable," offered Tim Schulenburg, Managing Director of Schulenburg Architekten.
The engineering takeaway
Conventional construction still carried the foundation, base slab, floors, and roof.
For manufacturing and construction professionals, the notable step is organizational. Matthäi Schlüsselfertigbau is not only associated with a printed headquarters; it has launched a construction 3D printing division after seeing the process through on its own building.
