The new Mobility Hub comprises four parking levels with a gross floor area of 6,400 m². The columns, beams and bracing are constructed from glulam. As there is no façade, structural wood protection was provided on the external surfaces of the structure by cladding with three-layer larch panels. The floors, including the entry and exit ramps, are constructed from cross-laminated timber (CLT). The CLT structure is covered with approximately 80 mm of mastic asphalt as a waterproofing layer. The roof consists of glulam with trapezoidal sheets and is also included in the WIEHAG service package. It was designed as a green roof and fitted with a photovoltaic system.

The particular challenge: the car park is being built in earthquake zone 3 – the highest zone in Germany with a high seismic risk – and is therefore subject to the highest structural design values. The bracing was installed only in the building’s central axes to avoid having to run it through the larch cladding.
