For the architecture firm RAr-2 Laboratorium Architektury Gilner & Kubec, the natural colour effect of the facade of the Copernicus Science Centre in Warsaw was important. The building envelope was to consist of different puzzle pieces in various colours. concrete skin is therefore ideally suited for the facade. This design concept lends the museum its unique ambience. The building radiates modernity as well as progress with a profound respect for nature and its unmistakable secrets. Rieder developed its own special colours for this project. Photos: Rasmus Norlander
