White architectural concrete for the Sevens Center in Düsseldorf

The Sevens Center, which opened in October 2000, is located directly on Düsseldorf’s famous Königsallee (“Kö”). The name refers to the original concept, in which each of the seven floors was designed around its own theme. Eleven years later, large-scale renovation work was carried out, during which the entrance areas to the shopping center were also visually upgraded. The main entrance on Königsallee and the side entrance on Steinstraße were precisely clad with white architectural concrete from DUCON. Wall, ceiling, and column cladding with element thicknesses ranging from 45 to 70 mm (1.5 to 3 in) and element lengths of up to eight meters (26 ft) were used.

The goal was to achieve the most elegant and high-quality appearance possible for the areas clad with prefabricated elements. To this end, pieces of marble were embedded in the formwork during production; these were then highlighted as a visual feature through subsequent grinding and polishing of the surface. On the construction site, the elements, some of which were curved, had to be mounted on the existing structure with minimal tolerances so they could be assembled like a puzzle to form a seamless surface. Thanks to the excellent cooperation of everyone involved, all 34 elements, which showed virtually no repetition, were installed with a perfect fit and continue to adorn the entrance areas of the shopping center to this day.

Project data:

• Execution period: 2011
• Wall, ceiling, and column cladding with a component thickness of 40-75 mm (1.5-3 in)
• 34 elements with a total area of approx. 225 m2 (2420 ft2)
