The school is organised as a network of classrooms and courtyards along a central corridor. The classrooms are grouped in pairs, sharing a group of bathrooms. This core has independent access and visual control from each of the classrooms. Each group has a private playground, which has the function of extending teaching activities outdoors. Close to the main entrance, we locate the multi-purpose room, functionally linked to the hall. The teachers' room has a centre of bathrooms adapted to people with reduced mobility, as well as the kitchen and warehouses. The connection to the existing Nursery School building is made through a porch extending the interior corridor. This connection has made it necessary to open a new door in the rear façade of the current centre and to rearrange the interior of a small room. The entire new building has been built with a system of load-bearing walls, of large-format ceramic pieces (2.00 m x 0.60 m x 0.20 m), supported on continuous concrete shoes on foundation wells. The truss and the crowning of the pieces is done using metal bands made of concrete blocks to be seen. On these walls there is a structure in wooden beams 28 cm wide that are left visible.
