The design is an extension of the National Library of Austria from the Beijing-based architect Chris Prechteck. It is located close to the castle in Wien and contains a number of cultural facilities, creative studios, restaurants and shops. The spiraling structure offers 1 200 square meters of exhibition space as well as 600 square meters of underground multifunctional space. The spiraling structure features a mosaic form of crystal-like excisions along its body, allowing natural daylight to filter through to the interior. The movement of pedestrians in the streets has not been affected in any way. It creates some kind of an arch and the roof functions also as a garden. The solid structure offers at every point a different spatial experience and intuitively leads the visitors to the entrance hall.
