For several years, the new building of a budget supermarket in the Mannheim district of Rheinau had provoked fierce controversies. Residents were deeply concerned about the noise of deliveries and additional traffic caused by customers. With a competition-like procedure the town aimed at finding solutions for the design of the façade, and the integration into the urban context. The chosen urban design proposal complies with the requirements of the noise survey. Together with the adjacent new building of the TSG Rheinau sports club, the budget supermarket forms a unit integrated into a landscape concept (Studio Grijsbach Landschaftsarchitektur), which also includes the required parking spaces for both buildings. Our façade concept features a layered design which allows the operating company of the budget supermarket to fall back on their standardised construction method. At the same time it establishes a conceptual reference to the surroundings. The main building of the supermarket is wrapped into an envelope of individual metal sections, with a continuous height of 8 metres. The building envelope incorporates the delivery zone, and the HVAC areas on the roof. It transforms the restless, heterogeneous building volume into a calm cube. The utilised sections comprise steel V-angle bars, with a width of 15 cm, and a depth of 20 centimeters. These are arrayed with a spacing of 25 centimeters. A semi-transparent effect has been achieved by the depth of the sections. Depending on the perspective, the envelope appears open or shut; concealing or revealing. This second skin filters and reflects the incident sunlight in different ways. The resulting play of light and shadow enlivens the tranquil building volume.
