Each floor consists of an irregular pentagonal shape rotating around the vertical core, which is supported by an exterior steel framework.

The local politicians deemed it important for the inhabitants to have a new symbol for Malmö in lieu of the crane that had been used for shipbuilding and somewhat symbolised the city's blue collar roots.
