Inspired by the movement of a conductor´s baton, the building design is composed of five concrete roofs moving up and down in harmony to give shape, space and light to the project. Each roof represents a musical staff´s line, always straight, constant and parallel. We wanted to create a project that lives for the trees as the trees live as a part of it. We cannot think about a dark and traditional concert hall when the project site is in a forest area with huge and old trees.
