The Wolframstrasse special unit could provide space for concerts and other events in the field of music culture. It is also conceivable that the building could also be designed as a conference center for small to medium-sized events in order to make it available for use around the clock. Citizens, clubs and schools will also have the opportunity to use this future building block as a rehearsal room, for example.
