"A warmly glowing, floating metal sculpture" is how the architects at pape + pape describe the new bus station they designed for Gummersbach, Germany. Sited by the train station, the new structure creates a striking image at the entrance to the country town.
For more than a century Gummersbach was home to L. & C. Steinmüller, which founded a a tube and steam boiler factory in the city in 1874. Gummersbach and Steinmüller were inextricably linked until the early 2000s, when the latter went bankrupt and moved its operations elsewhere under new ownership. Although a great loss for the city, the situation was also a great opportunity: Gummersbach bought the 18-hectare brownfield site, demolished most of the buildings, and erected a shopping center, sports arena, technical college and park as part of the Local 2010 urban develpment plan. The bus station, located on the eastern edge of the site, strengthens connections between regional train and local bus transportation.

Gummersbach's old train station was demolished as part of the plan, and the bus station was relocated here. For this new location pape + pape designed a 130-meter-long, 10-to-25-meter-wide roof whose form and materials are a worthy prelude to those entering the city. It follows the gentle curve of the train platform and consists of a polygonal folded form inspired by the broken structure of rocks in the area. Aluminum bronze shingles on the underside of the roof shine golden, an effect strengthened by the darkness of the concrete base and the angled concrete columns supporting the roof.

At night the golden shingles really glow, thanks to Lichtwerke's lighting design. According to managing director Stefan Hofmann, their design addresses security concerns, which are a top priority in projects like this, while also reinforcing the qualities of the architectural design. The former comes in the form of powerful direct lights set into the roof that illuminate the platforms, while the latter involves indirect uplights that highlights the gold shingles. The indirect lighting is made up of LED light bands (Insta Elektro's Instalight LEDLUX LH und LS) that are installed atop the glass walls that span from column to column and shield the adjacent wood benches from the wind. These benches give the passengers a secure, sheltered space to wait for their buses, yet one that receives some drama from the glowing metal sculpture overhead.
Lighting of the roof is hidden in the linear light strips above the angled glass walls behind the benches. (Photo: Lukas Roth)
