The concert room has two parts : the first one is horizontal – the scene –, and the second one is sloped – the tier.

To close this space, we conceived a roof which has the same angle as the slope, and three facades which also have a role for the propagation of the sound. Together, they strengthen the proto structure.

The two spaces are separated by a diagonal. It creates a larger place for people by extending the scene. This also determines the limit between the Performer and the Spectator.

From the fragment to the protostructure.
