The office building lies on the edge of bustling Praterstern square, the most attractive open space resource in the city of Vienna. Covering an area of about 5,000m², the new 8-floor office building consists of two almost parallel structures with a central atrium.
Although eight different façades types were used, the most interesting design aspect of the office building is the foil Texlon® ETFE technology. With a span of 26m, the construction covers an area of about 1,000m² and is supported on 13 steel trusses. Thanks to the foil cushion roof, the supporting structure is considerably lighter than would be necessary for a glass roof. What’s more, the double layered Texlon® ETFE foil exhibits a self-cleaning effect due to the chemical surface properties, and provides solar shading as well as thermal insulation.
With its curved contours and delicate steel frame, the roofing envelope design is simple and modest, allowing for maximum light transmission in the central atrium while stylishly complimenting the existing building structures.
