The thick rammed earth walls of the media library are excavated-like, unearthed as in an archaeological site. They delimit the open spaces and enclose alcoves dedicated to listening and concentration activities. Fired ceramic slabs using ancient techniques are embedded in the rammed earth walls and are used for the building signage. The roof is designed as a stainless steel «box», mirrored on five sides. Surroundings reflect on it in a changing way, according to where you are and to the light: the roof dilutes itself and merges with the surroundings it reflects, and its outlines disappear. This changing roof refers to the idea of the immateriality of the stored data that is permanently modified.
