Experimentarium

When you walk into Experimentarium in Copenhagen you are greeted by a glorious sight – a copper-clad spiral staircase with a total length of 185 metres that connects the building’s floors.

The HELIX staircase was designed by Kolja Nielsen from CEBRA Architecture, and he notes that it is in fact two intertwining staircases, and is an interpretative image of the strings in a DNA molecule. So in addition to serving its purpose as a staircase, HELIX therefore symbolises life, and the science that is the focal point of the popular experience centre.

The unique spiral staircase consists of eight large steel elements, which were lifted in individually during the renovation of the Experimentarium, and assembled in situ.

The total staircase weighs 280 tonnes, and was produced, delivered and installed by CSK. The 10 tonnes of copper were subsequently installed by AE Stålmontage.
