The F.3 aquatic centre combines three separate areas – the sports area with indoor pool and open-air pool, the adventure pool and the sauna world. These areas have been transferred into a flowing form that gently blends into the landscape and picks up on regional aspects in both shape and design. The location on the western edge of the town of Fellbach near to the Kappelberg was the starting point and the guiding theme in shaping and designing the new amenities. As one of the well-known vineyards in the region, the Kappelberg and the theme of wine provided the basis for the architectural concept. To formally incorporate the building into the landscape, the linear vineyard structures were laid onto the plot as fields. The material and colour design is also in keeping with the guiding principle of the architecture. The central design element are mosaic tiles which reflect the changing seasons.
