Project description

Spiral stairs in the savings bank in Bayreuth

The banks’ customer centre at the Luitpold Platz in Bayreuth opened after only two years of construction. The self-supporting spiral stairs with folded steps take centre stage in the two-storey lobby of the new building. Beside the imposing sculptural character the attractive lacquering of the spiral stairs results in a perfect integration into the interior style of the building.
