Clinicaurbana works on the abandoned portion of a building just outside Treviso city centre. Its inexpensive make narrates its history: the brick fragments that constitute the walls are War World 2 debris used as recycled construction material. The river bight over which the house sits has been deformed by the blasts, and the building is part of the Sile River Park conservation area despite its lack of specific architectural quality. The constraints on the building exterior configuration together with the limited budget determine the design strategy and the technical solutions. The internal partitions are unchanged in order to limit demolition and reconstruction operations; the core of the design strategy is to strengthen the spine wall, using a load-bearing concrete mortar treated as a finish plaster. The new iron and timber stair is fixed onto this same wall. The relocation of the stair makes room for two toilets at the two main levels and for a study at the attic floor.
