Children do not remember the classrooms in their school but the playing grounds, the corridors and the yards; on the other hand, they also remember the good teachers and some anecdotes with their fellow students. These memories, that accompany them for their whole life, depend very much on the Architecture because it makes possible to change into joyful what could be, sometimes, only sad or melancholic memories. The purpose in this project was to have a clean, bright and cheerful building.Any student of an Architecture school knows how to resolve an educational program: classrooms and laboratories; but what distinguishes the best architecture is not to project the obvious and compulsory sppaces but the apparently useless spaces (yards, halls, empty spaces, exterior finishes,etc.) that enrich, articulate and allow to develop in freedom the students’ learning at the school.The building extends itself along the street, closing with low walls and behind little yards covered with lawn that could be used as open air classrooms in this area where the weather is fine almost all around the year.From the point pof view of a pedestrian, from the street outside, we can see the fence walls and the low two-floor blocks where the classrooms are placed, which are oriented towards the North and the East, using the third floor for the workshops, the library and the teachers’ rooms, looking to the interior part of the plot with the far and beautiful views of the Gredos’ mountains.The ensemble of the yards, the lineal developing, the finishing with prefabricated pieces over the brick basement and the building’s general image create an ensemble of a clear institutional nature dedicated to education.
