The project consisted on the rehabilitation of the old school building, dated from the 1940’s of the past century, and its concurrent extension. Located in the historical center of Lisbon, it reflects an ensemble of guidelines and requirements by the school’s education project, and fulfullis the needs of contemporary teaching/learning models, as well as energetical and environmental concerns.

The existing building was reorganized, with the establishment of a central core with the spaces of greater collective use (library, cafeteria, etc.), operating as well as an interface between the classroom areas and sports areas. A new floor, under the existing ones, was added, where the main entrance of the school is reached by an external ramp that culminates in a courtyard, the doorway of the building.

The new additions refer to more specific areas - technologies, laboratories, music, theatre and sports - for- mally differing from the existent through different covering strategies, either greenwall or polycarbonate. The presence of the old city wall, re-discovered during the preparation works, changed the landscape design and the initial position of the new sports court, in order to preserve the heritage.
