The curved shape and harmonious paintwork blend seamlessly into the ambience, and the staircase becomes the artistic centerpiece of the building.

Individual spiral stairs

After just two years of construction, the Sparkasse customer center on the south side of Luitpoldplatz in Bayreuth opened at the end of 2016. The focal point of the new building is the two-storey customer hall, in which the self-supporting spiral stairs with folded steps are located. The sculptural stairs blend perfectly into the ambience, not least thanks to their matching paint finish.
