Based on the motto “Many things should be different, not much should change“, we developed a new overall concept for the open-air swimming pool in Dreieich. The baths were originally built early in the 20th century and were last converted in the 1970s. Based on the idea of the “pool area as a piazza“, the functional building and leisure areas were placed around the pool areas. In addition, the existing pools were completely renovated and designed in their present form as an interconnected platform. The elements are aligned at right angles and in clear geometric shapes, corresponding with the facility’s main axis. In allusion to the name “park baths“, the colour green is a common theme in the new pool, both in the design of the buildings as well as the new plant areas.
