The Muziekpaleis project is a collaborative venture of Muziekcentrum Vredenburg, Tivoli and Stichting Jazz en Geâ€¢mproviseerde Muziek Utrecht (SJU). These organizations will become one company. The diversity of music styles and expression will remain. The design concept's starting point is a diversity of concert halls under one roof, whereby each hall or "biotope" has its own character. This diversity is obvious from the outside. The Muziekpaleis has five halls, one for each biotope. The existing main auditorium is dedicated to the symphony biotope; the four new halls will be positioned above or beside the symphony hall. In the design the different halls are clearly recognisable. The fact that the halls are kept separate (partly for acoustical considerations), and will be further elaborated by different architectural firms serves to reinforce their diversity.
