construction has begun on ‘crossoverzaal’, a project by dutch firm NL architects in utrecht, the netherlands. the idea was to design a music building with 4 halls on top of the existing concert hall vredenburg – bringing together totally different target groups in one building. in addition to the symphony hall, the complex will feature a 2000 person hall dedicated to pop music, a jazz hall, a room for chamber music and the so called ‘crossoverzaal’.

the ‘biotopes’ will be developed by 4 different architects within the masterplan by herman hertzberger/architectuurstudio HH.

the crossoverzaal will serve as an independent hall that can be used for a wide range of performances. but it can also function as a ‘safety valve’; when other rooms lack capacity for certain events.

 

the ‘biotope’ includes a spacious foyer and a flexible hall with a flat floor. it doesn’t have a fixed stage or fixed seating. the basic configuration holds 400 seats, but can contain up to 600 people. the hall itself is a box. balconies and ‘loggias’ are connected to it in an irregular way, bulging out of the main volume.

the starting point is the box in a box principle. the acoustic cavity in between the the inner and outer layer is locally enlarged to fit the buildings infrastructure and additional program.
