The Otranto project was part of a UNESCO-sponsored rehabilitation center rehabilitation program, and a 'neighborhood lab' was developed, based on total collaboration with the inhabitants. The roots of the architect's work were brought to light: the service role, the community's technical gesture, the symbolic value of the building. The activities were carried out around a 'cube', a transportable module organized into four sections: analysis and diagnostics, information and teaching, open project, work and construction.
