The stepped structure brings the urban form to a close. The design and the materialization of the facade underline the public character of the building. The setting naturally creates a school building with a novel typology and well defined quality outdoor spaces. The nature of the stepped levels combined with the overlap of the gymnasium form an exellent starting point for the design and development of hall-like corridors and downwelling flights of stairs. The escape routes lead over the rooftop gardens to the outside allowing the indoor circulation areas to be used, decorated and furnished without restriction.
