Construction Diary: Insights into the Construction Process
RUWI We’re growing—and doing so sustainably. Right here in the Black Forest, we’re building our new company headquarters. And because our roots run deep in Fluorn-Winzeln, we’re building it right here.
In this construction diary, we'll take you behind the scenes. You'll see how an initial sketch becomes a reality, step by step.
October 2022
Our ideas always start in our own workshop. We built the first design of the new building ourselves as a prototype—which was a practical way to understand what we really needed. Our previous workshop had become too small, and its location right in the heart of town left little room to grow. We wanted to get RUWI ready for the next generation and create more space for future developments.
October 2024
After extensive planning, the time had finally come in October: Together with Mayor Rainer Betschner and our architects from W:Architekten (now Arc+) in Freudenstadt, we celebrated the official groundbreaking.
November 2024
The topsoil layer was carefully removed. Now, five dump trucks are operating on a shuttle basis, transporting the excavated soil to a nearby landfill.
December 2024
The construction professionals are digging strip foundations, and the first concrete is arriving at the construction site. We have taken special care to ensure that the foundations can withstand the loads from our machinery and workshop equipment.
January 2025 (Concrete Core Activation)
Before the concrete was poured, we installed about 4,000 running meters of tubing within the reinforcement. The concrete core activation system will later use this tubing to heat and cool the building—together with air-source heat pumps, it supplies the building with heat from renewable energy.
February 2025 (floor slab)
Our construction partner, Sieber, poured the concrete foundation slab in three sections. The result is a level, load-bearing surface—the foundation for everything that follows.
May 2025
It was clear to us from the very beginning: Our wood comes from our home region. We made a conscious decision to use CLT elements from Holzbauwerk Schwarzwald —because of the short distances involved, our connection to the Black Forest, and our sense of responsibility toward the region. Piece by piece, the carpenters (Ginter Carpentry) are assembling the components—and our new building is taking on its distinct shape.
June 2025 (roof and solar array)
The roof is complete; seven truck trailers full of roof panels have been installed. The solar power system is designed to meet as much of our energy needs as possible with electricity.
July 2025
Interior construction requires craftsmanship and creative solutions. Window installers, electricians, heating and ventilation specialists, and drywall installers are now on site. We deliberately chose local contractors and held many discussions with them to ensure they’re a good fit for our company. The interior is taking shape quickly, and the construction site is bustling with activity.
We plan to move in at the end of the year. Preparations are already underway, with every step carefully planned so that we can get up and running smoothly. We look forward to filling the new building with life and a passion for our craft.
August 2025
Work continues on the construction site. The outdoor areas are now taking shape. Thirty-four truckloads of gravel are laying the foundation for paths and open spaces—solid and stable, serving as the base for the asphalt.
September 2025
There are also some changes taking place inside: The warehouse is relocating, and new structures are being put in place. A rack is currently being assembled that will provide space for up to 260 pallets—an important part of the future logistics operations.
October 2025
After a short break, work continued on the exterior. The parking spaces were paved, the carpenters installed the final exterior slats, and the final sheet metal work was completed. From the outside, the building is now virtually finished—the project is entering its final phase.
November 2025
We’ve arrived. The new home of RUWI is located at Obercarsdorfer Straße 10 in 78737 Fluorn-Winzeln. What began as a preliminary sketch in 2022 has become a wooden building where work is now being carried out.
Behind the wooden facade, the machines are running, the warehouse is stocked, and the development team continues to tinker with the next idea. The ceiling made of locally sourced wood—which we watched being installed—now supports our workshop.
Right in the thick of it, our own tool is in action: the lifting table 400 XL Cordless, which can lift up to 400 kg electrically to working height . That’s exactly why we founded RUWI —tools from the workshop, for the workshop.
We're looking forward to this new chapter and the time that lies ahead.
