The project is organised around two main corridors. In one are located all the classrooms and the parts of the programme related to the teaching activity and the other supports the vertical communications (stairs and lifts) and the different services (toilets, storerooms, cleaning areas and facilities courtyards). In this second bay, there are also some spaces that give access to the toilets and stairs, allowing the users of the building to stay and rest. These are the connections of this first phase with the future extension of the building. These two bays are joined in a linear space where the public staircases and the staircases linking the different floors are located. On both sides of the central axis are the installation courtyards that bring the different elements of the air conditioning system to their respective classrooms and to the corridor that absorbs the main horizontal communications.
