As part of a major initiative to modernise schools and educational facilities in the city of Düsseldorf, the Friedrich-Rückert grammar school renovation represents a first step towards the future. In addition to renovating the interior of the school, much work was done to make the exterior of the aging building look more modern, inspiring and inviting. The new 3,000 m2 facade made of glassfibre reinforced concrete panels from Rieder bridges the architectural gap to the here and now. The innovative concrete is a symbolic step towards sustainability, fit for a modern school building. The new texture twine was also used for the first time in this project for the colour-matched formed parts, skilfully highlighting the building envelope.
