The adjacent ancillary building with its logistical and technical functions was realized as a timber hybrid construction: apart from the concrete stairwell cores, the building was erected as a timber frame structure of approximately 600 timber elements. The facade was realized using timber panel construction with timber cladding. To further articulate the volume and reference the surrounding residential development, the sports hall features a folded shed roof while the ancillary building features a flat roof.

The various requirements have resulted in a large volume and a variety of designs. To achieve a clear façade design and an appropriate scale in relation to the urban context, the sports hall was divided into a semi-transparent façade. At the same time, this allows the use of the building to be vaguely guessed from the outside. While the sports hall appears in a light-grey curtain wall facade, the ancillary building received a characteristic larch timber facade.

The sports hall is accessed at ground level via the forecourt, which also serves as an outdoor foyer for visitors. While sports clubs and schools use the side entrances leading directly to the changing rooms for the lower halls, event visitors enter through a generous entrance area into the lobby and from there to the grand stand, which provides seating for 500 spectators. Changing rooms for the upper halls are located on the first floor; the second floor houses staff rooms, weight rooms, gymnasiums, and a gallery level with views of the hall featuring a bouldering wall. Not only the halls themselves but also the gallery level can be separated by dividing curtains.

The clear overall architectural concept is reflected in the interior design: each floor has its own colour scheme and materials. Here, too, the use of resource-saving materials was taken into account and care was taken to use as little material as possible.
