Dekton Zenith modernises Volksbank's image with a ventilated façade in Müllheim

The Volksbank headquarters in Müllheim has undergone a comprehensive transformation that goes far beyond aesthetic renovation. The project, led by Eggen Architekten GmbH under the direction of Mario Eggen, proposes a complete modernisation of the architectural envelope to update the building's image and strengthen its presence in the urban environment. One of the main challenges was to replace the old dark natural stone façade with a contemporary and lightweight solution, capable of enhancing the building's brightness and visual impact. This is where Dekton by Cosentino comes into play.

To achieve this, the team designed a ventilated façade system using pure white surfaces that bring clarity and modernity to the ensemble. The chosen colour was Dekton Zenith, applied to the main façades and the new access tower connecting the building's various volumes.

Thanks to Dekton's excellent mechanical properties, Cosentino's ultracompact surface becomes the ideal material for a façade. These include its resistance to UV rays, freeze-thaw cycles, abrasion, and stains, as well as being non-combustible. Cosentino also offers a 25-year warranty for this application and a commitment to sustainability with its Carbon Neutral certification.

The chosen fixing system for the 12 mm thick Dekton slabs using undercut anchor bolts (DKT1) is a mechanical and concealed solution, certified by the European ETA 14/0413. This solution is highly robust and effective, allowing façades to be resolved with great versatility, adapting to diagonal cuts and the most extreme conditions.

The project also integrates a suspended structure with movable photovoltaic panels on the south and west-facing façades, enhancing the energy efficiency strategy and adding dynamism to the composition.

The choice of this material responds to both aesthetic and functional criteria. According to the architect, its quality, construction performance, and maintenance advantages were decisive. Furthermore, the bank had previously used a Cosentino surface in another of its buildings and had a positive experience.

This continuity ensures a coherent visual identity across the corporation's buildings. Now, the new façade of the Volksbank building stands out with its elegant white finish.
