The principal needs for this school project had to do with principles of modulation and the use of traditional techniques of construction. The site place is flat and according to the program and physical relations in the site it was a natural thing to do to divide the school in five different blocks: administration, classrooms and laboratories, restaurant and service areas, library and computer’s room, and media theatre. These volumes are connected by metallic structures and surrounds a internal playground. This organization allows at the same time to take advantage of natural ilumination, ventilation and still stimulate external lective activities.
