The extension is located in the southern part of the school site, occupying part of the platform on which there is a classroom room without the main body of the school. This disposition of the newly built body trims the outdoor sports track located on the third platform, modifies the access ramp from the second platform and eliminates the scale that saves from the unevenness between the open exterior passage of the plant attic of the workshops and the Third platform, where the gym and one of the outer tracks are located.

Given the slope of the terrain on which the enlargement building is located, the ground floor is used on its north side on the ground acting as a wall of content on the sports floor of level 3, which, as is already the case he said, it is diminished in its length.

On the west side of the expansion, between the building and the perimeter fence of the plot, there is a ramp of circulation that forms part of the road pavement of access to the school and, and this ramp, will be on the sports track of level three that stays in its current level, so to the west side is constructed a new paved road in ramp that will be the access of trucks to the center of the school enclosure, by use of firemen and maintenance.

On this road there is also access to the kitchen-catering center that goes to the building of the extension.
