This intervention in the historical center of Turin is based on a project-management collaboration between Italy and Norway. A working team has been created, where the all the diff erent phases have been daily shared and discussed via Web, to allow a limited dispersion of data. The project, developed in Oslo, was then defined and feasible from an earlier estimation that allowed the determination of the full costs before the beginning of the construction phase. The ideation has undergone in a very limited changes in its course, some to adapt to economic needs, some to adapt to construction requirements, but it remained almost unchanged in its initial character. It has been defi ned, from the very beginning, a reversal of the kitchen with the room on Via Arsenale, giving the living area, a continous and long appearance.
