Building concept: The space problem on the small square was solved by using three levels with different functions. The upper level houses basketball and tennis halls with 2,500 spectator seats. The 85 x 42 m area is spanned without a central span. The lower level contains the changing rooms, the swimming pool, handball courts, and workshops. All building services are located in the space between the columns and their cladding, or run along the outside of the columns.
