The roof of the exhibition hall, a laminated wood space structure, was erected in 1987 under the direction of the engineer M. Van Wetter.
The owner wanted to transform this palace – measuring 140m by 71m – into a concert hall. Therefore the existing wooden structure needed to be strengthened for two main reasons:
– to make it comply to the current standards, particulary with respect to the loads of the wind.
– to ensure the static for suspension of significant scenographic loads to the roof structure.

In order to achieve these objectives the existing structure has been reinforced with the aid of an additional structural steel sheet. Thanks to this, a large static height is constitued, this eliminates the bending moments acting on the nodes.

Now, the two thin wooden sheets form an architectural ensemble that expresses the new function of this scenographic place.
