The new headquarters are open and dynamic and display a high level of design quality. The façade cladding is made of anodised aluminium, the interior offers optimal working conditions: generously-sized horizontal window strips which also extend across the diagonal provide adequate daylight for the offices; core concrete activation and a ventilation system with heat recovery create a pleasant working environment in an environmentally friendly manner. The elliptically curved spiral staircase in the centre cites the "O" in the company logo and forms an exciting contrast to the rectangular-shaped building.
