The aim of this competition was the rehabilitation of three adjoining buildings in the Oporto historic city center. The proposed design is a reaction to the rehabilitation politics used in the Oporto Historic Area. The existing buildings are characterized by a high state of degradation and by their very small size. After the removal of all the wreck of the interior, only the major stone walls will be kept. Three volumes are inserted on the empty existing buildings. These are build in a light wood structure, like the old constructions, separated from the facades, distinguishing the new and the existent.
