Norderstedter Bank Treppenauge

Spiral staircase in the bank of Norderstedt

Impressive rounded designer staircase

With an elegant, cantilevered designer staircase, MetallArt managed to impressively connect the four floors.

Project description

Designer cantilever staircase with LED handrail lighting

After the merger with Volksbank Itzehoe in 2018, Norderstedter Bank moved into its newly constructed office building on Berliner Allee in Norderstedt at the beginning of 2020. MetallArt managed to impressively connect the four floors with an elegant, cantilevered designer staircase. The white balustrade-high steel stringers contrast harmoniously with the wooden steps made of European oak which were realised in cooperation with our partner company Holz-Hacker.
The anti-slip step lacquer on the designer staircase provides the necessary safety.

Due to the statically supporting, smooth-surfaced soffit cladding, the designer staircase looks like a sculpture.

The highlight is the lighting system specially developed by MetallArt.

At the ceiling openings, the all-glass gallery railing stylishly blends into the simple but effective ambience of the bank building.
