Together with landscape architect Klaus Wiebold Ulrich Tillmanns presented the design for the new aquatic centre to the public at a citizen meeting on the "Heloponte II new construction project in Bad Wildungen". Due to the beautiful location and the special features of the site – a stream flows through the area – the nature theme plays a key role in the design of the aquatic centre and surrounding area. For example, the design includes a natural swimming pond and the extensive sauna garden will also have a natural bathing pond.
