The intervention develops a building for 18 classrooms of primary and 12 of children with its corresponding outer play areas. The layout of the volumes in the plot allows to obtain a greater use of surface for patios. To the north, a single sloped roof gives unity to the building.

The contrast between the horizontal ripped holes of the tall plants and the variety of those on the ground floor gives a richness to the image of the building while providing a scale closer to its future users. To the south is the outer covered court, a body dressed in a translucent skin that acts as a night lamp.

The architectural and functional design of the spaces is based on the characteristics of this type of buildings. The use of a frame of 7.2x7.2 m. it generates readable, rectangular, diaphanous and flexible spaces that allow to approach actions of reform and extension.
