The rectangular volume, measuring 77.40 x 16.50 meters, runs parallel to Bernat Desclot street, from which the kitchen and sports fields are reached. The main entrance is at the corner closest to the urban center, where Bernat Desclot and Jaume Vidal i Alcover streets meet. The building is detached from the limits of the plot so that all its spaces are visually connected with the courts and playgrounds.

The orientation chosen, with main facades looking northeast and southwest, permits organizing each level from a central corridor, with classrooms and other spaces on each side. These corridors start out at an open, triple-height lobby located at one end, where the main access is placed. This space defines the building, and becomes its main gathering area. Terraces bring light into the corridors, functioning as study and breakout areas.

The enclosures are finished with prefabricated concrete, with special attention to lighting and acoustic control in the classrooms. Orientable fins colored in silver and yellow create a distinctive facade image and shade the classrooms. The system of slats is interrupted only by terraces framed in gray, like large-scale windows.
