Central bus station canopy Wiesdorf

Leverkusen 2020 (D)

The canopy over Wiesdorf central bus station (ZOB) in Leverkusen is an elliptical structure, measuring approximately 117m in length, approximately 24m in width. The membrane structure consists of 8 membrane panels. These are clamped to an edge beam along the periphery. Each membrane panel has been designed with a circular low point, creating a 3-dimensional surface curvature.

Two circular portholes provide additional light under the roof.

The fact that the warp of the membrane material runs radially from the circular low points to the outer edges was factored into the form-finding process. As a result, tangential seams in the membrane were not required, benefitting both aesthetic and structural aspects.
