The base of the angular building serves as venue and customer information centre. On top there is the Wunderkammer des Brotes, a museum which highly fascinates due to its outstanding architectural design. The self-supporting spiral stairs with parapet-high stringers represent the heart of the museum. Walking on the spiral stairs the visitors have a perfect view on the floating objects referring to bread and baking. The natural light shining from the roof onto the spiral stairs creates the unique atmosphere. Apart from this, the museum is only sparsely lit.
The company offers the entire engineering – 3D construction, static calculation and production – in a one-stop-shop. For the spiral stairs the design engineering was completely realised with CAD. This enabled various displays from any perspective requested.
It was extremely challenging to mount the spiral stairs as it was transported in large sections (approx. 4,5 tons each) with a building crane from above via the open roof. By means of a concrete collar the stairs were finally installed. Beside the verifiable structural calculations for the spiral stairs MetallArt was responsible for the complete mounting construction.
The spiral stairs were awarded for the “staircase of the year 2017”.
