An empty area on the roof of the logistics center at the southwestern end of the campus was used as an acquired building site for the new 7,400 sqm sports center. The center, located roughly 30 meters above ground level, is accessed via long external stairs (part of the training parkour) and an elevator for transporting people and goods. The building is organized into two areas: a fitness, yoga, and class area with a foyer and changing rooms as well as a sports hall with three playing fields used by TRUMPF’s company sports clubs and teams for basketball, soccer, and badminton. The remaining roof was extensively planted and offers a panoramic view of the corporate campus.

To decrease the weight as well as the CO2 footprint of the rooftop construction, the extension is a prefabricated timber construction of simple and economical laminated spruce that form a 1-story volume with a mezzanine. The clear span of the trusses in the hall reaches 23,5 m, with a height of up to 1,2 m. In the area of the fitness spaces, the span width is halved. The glazing of the southern façade consists of a continuous double façade (to protect acoustically from the loud Autobahn), supplemented in the area for exercise machines with an insulating glass layer and wind-protected sun protection.

The sports hall has no insulating glass, which is merely replaced with protective netting. Translucent polycarbonate panels close off the space to the north. Large sliding doors to the rooftop garden provide fresh air ventilation to the sports hall. The sports center volume hovers above the Autobahn and agricultural fields and by night acts like a glowing lantern.
