The project constitutes the second part of the school in the desert project, from which it adopts the technical choices and constructive techniques. The existing building will be in this case completely modified. The new library is proposed as a new volume of squared plan articulated in two areas: From one side, the main reading room, defined by library-walls and completely opened to the outdoor space, becoming a place for meeting and passing-through, and from the other, the service areas, more closed and protected. This articulation is expressed as well in the roof, solved in two opposed slopes, which recreate the natural ventilation mechanism from the school in the desert. The indoor spaces of the library are linked to the outdoor ones by the modular pergola made of bamboo panels. A system of phyto-depuration pools, for the harvesting and re-use of raining water, re-links the school-library and outdoor spaces in an overall single design.
