An aerodynamically shaped transparent glass envelope immaterially defines the corner’s volume – its subtlety is allowed by an air-ventilated double glazed façade. A contracting cubic austere mass appears in the second plan established by a layer of adjustable golden screens responding to the interior lighting comfort. On the building’s most prominent place, an internal prism works its way through the calm horizontal mass establishing the dominating tower – a vertical response to the opposite corner with the Koruna Palace. Behind the lightweight glass skin, calming the building’s overall effect down, the mass of the office part is removed where necessary due to the links to adjacent buildings.
