The former factory location of agricultural machinery manufacturer Rasspe is the largest site with commercial potential in the city of Solingen. Due to its central location in a development area of nearly 400 companies, institutions and research institutes specialised in the field of post-fossil and digital economics, the 6.5 hectare site has huge potential. Solingen organised an urban development competition to revitalise the vacant site. De Zwarte Hond convinced the jury with a modular, circular and flexible concept that responds smoothly to the rapid evolution of the new digital economy. The urban restructuring is accompanied by a large-scale soil remediation that the City of Solingen has started together with the Verband für Flächenrecycling und Altlastensanierung. The former monumental office building has been spared, and will form the future address of the new business park: an unmistakable calling card. In the plan for Stöcken 17, business activities are not seen as static. That’s why the different locations in the area are designed for various uses. Because the business park of the future is also a living space, the companies are situated around a central heart, where staff and city residents can meet.
