The client intends the establishment of a new music theatre which should sould set a clear accent into the urban surrounding. The positioning of the building is based on functionality, the traffic-solution and the recognition as a "music-theatre". The character of a landmark in relation to the north-south-axis ( Landstrasse - Wienerstrasse), and a clear orientation towards the public park on the opposite side of the road are the basic elements. A clear body, in the shape of a wedge, aims to seperate the railroad-tracks from the site. With an opening to the west, it underlines the north-south-axis. Dynamic surfaces are strengthening the structure in its form as a music-theatre of the 21st century.
