This grandstand building for an athletics and football stadium is situated in an important area for local recreation in the Basel region: Brüglinger Ebene. The new building meets the functional requirements of a grandstand and changing room facility on the one hand, while enriching the park grounds with its spatial and aesthetic quality on the other hand. Its architectural language refers back to the time when the sports grounds were established.
Pavilion: The grandstand building extends along the alley between St. Jakobs-Promenade and Mittlere Allee. Resembling a pavilion, the projecting roof that faces the alley spans a sheltered area. The delicate structure incorporates the rhythm of the row of trees, such that the long building respects the scale of the alley.
Stadium: On the stadium side, the roof projects further, protecting the grandstand, which is an extension of the existing spectator facility. Here, using the same architectural means, the building takes on a completely different appearance: that of a stadium. It is thus referred to as the "Padion" (pavilion/stadium).
The grandstand building's support structure comprises a solid seamless underground level made of in-situ concrete and an above-ground sophisticated prefabricated framework.
The seamless design of the long underground level, built in groundwater, is achieved via predetermined breaking points at intervals of 6.60 m. The roof structure consists of prefabricated two-pin portal frames with concrete slabs on top. These concrete slabs' longitudinal seams are reinforced with cast concrete, causing the roof level to act as a diaphragm. Longitudinal bracing is provided by means of the lift core and the prefabricated columns fixed in the slab above the ground floor.
The spectator seating is provided on pre-stressed step elements, which are supported vertically and horizontally by transverse ribs. All cast-in-place elements are made from recycled concrete.
