Supported by concrete columns, the main entrance with the adjoining administration wing "floats" six meters above the ground. Visitors arrive here via a sculptural spiral staircase, which rises in an elegant sweep to the outside terrace in front. One hundred and fifty vertically tensioned I-SYS stainless steel cables by Carl Stahl Architecture provide protection when going up and down the stairs. In different lengths of one to five meters, they follow the geometry of the staircase and, with a cable diameter of just four millimeters, appear filigree and visually reserved. In this way, I-SYS leaves the show to the impressive external staircase and at the same time offers the necessary protection as stable balustrade infill.
