Construction diary: Insights into the construction

RUWI is growing - sustainably. Our new company building is currently under construction right here in the Black Forest. And because our roots are deeply anchored in Fluorn-Winzeln, we are also building right here.

In this construction diary, we take you behind the scenes. You'll see how our idea is gradually becoming reality from an initial sketch.


October 2022

Our ideas always start in our own workshop. We built the first draft of the new building ourselves as a prototype - very practically, in order to understand what we really need. Our previous workshop had become too small and the location in the middle of the town center was not ideal. We wanted to make RUWI ready for the next generation and create more space for future developments.

October 2024

After intensive planning, the time had finally come in October: together with Mayor Rainer Betschner and our architects from W:Architekten (now Arc+) from Freudenstadt, we celebrated the official start of construction.

The humus layer was carefully removed. Five dump trucks are now in shuttle operation, transporting the excavated soil to the nearby landfill.

December 2024

The construction professionals dig strip foundations and the first concrete rolls onto the construction site. We paid particular attention to ensuring that the foundations meet the special requirements of our machines and workshop equipment.

January 2025 (concrete core activation)

Before the concrete was poured, we laid around 4,000 meters of hose for concrete core activation. This clever technology, combined with air heat pumps, will provide sustainable heat in the future.

February 2025 (floor slab)

Our construction partners, Sieber, concreted the floor slab in three sections. The result: a perfectly flat surface, ready for everything that follows.

It was clear to us right from the start: our wood comes from our home region. The decision to use CLT elements from Holzbauwerk Schwarzwald was a conscious one - not only because of the short distances, but also because of our connection to the Black Forest and our responsibility towards the region. Piece by piece, the carpenters(Zimmerei Ginter) are putting the components together - and our new building is slowly taking shape.

June 2025 (roof & PV system)

The roof is covered, seven truck trailers full of roof elements have been laid. The PV system is intended to cover as much of our energy needs as possible with electricity.

The interior work requires skilled craftsmanship and creative solutions. Window fitters, electricians, heating and ventilation experts and drywallers are now on site. We deliberately opted for local trades, with whom we held many intensive discussions to ensure that they were a good fit for our company. The interior is developing quickly and there is a lot of life on the construction site.

We want to move in at the end of the year. Preparations are already in full swing. Every step is being carefully planned so that we can start operations smoothly. We are already looking forward to filling our new building with life and passion for craftsmanship.

The construction site keeps moving. The outdoor facilities are currently taking shape. 34 truckloads of gravel are creating the basis for paths and surfaces. Solid, load-bearing and prepared step by step for the asphalt.
