The idea is to respect as much as possible the nature of this important park in Wien. The curved shape is given by the concept to tie the harmony of music to the nature. 

The building is divided in three floors where there is on the ground floor the main auditorium and in the others floors the music room, the rehearsal rooms, technical rooms and other rooms. The floors are  rotated around the fulcrum, stairwell, in this way the house of music creates livable terraces of different dimension for users. Nature is very important in this site (it is in the main park of Wien) and it is called also inside the buidling thanks to a small garden located between the restaurant and the exhibition hall. This garden can be seen by users of the first and second floor and from outside between the glass walls. Around the main stairs there is glass volume  that runs from the ground floor to the last floor giving natural light. The facades are in concrete and are subdivided in five timber lines to remember the pentagram and the capital of the music: Wien.  Outside there is a open concert hall where in the summer there are the musical activities.
