The leading idea of the design is to create a sculptural building, whose structure is accessible and therefore easy to experience. The Ars Electronica Center and the extension will be linked to one unit and perceived as a whole. In its neighbourhood the crystalline shape forms a homogeneous ensemble and a landmark. The urbanistic concept is based on on the prinziple of a dialogue with its surrounding. In consideration of urbanistic important conditions, like the preservation of the wide view over the Danube as well as the conservation of the historical ensembles, an attractive ambience will be generated. A construction consisting of steel and glass connects the existing Ars Electronica Center with the main and supply building. The partly transparent and partly translucent glass surfaces can be illuminated from behind. During the day, skylight windows, which can be opened, serve as a natural ventilation for the offices lying behind. The cube, composed of a double shell facade, can be used optional as a projection screen. Using the projection on the usable cladding at night, a transparent light sculpture with a high identifying feature emerges. Furthermore the facade can be populated with LED and LCD screens, whereby an additional information and announcement effect will be generated.
