The house, an old intervention of the fifties, has been completely reorganized with the aim of having fluid spaces, in which the interior and exterior are strongly interdependent. The total emptying and the construction of the central staircase, an element of hinge between the spaces, allowed us to create a mezzanine and a roof terrace. The opening of new windows and French windows, consistent with the existing façade, has created new views and the possibility to see the light change with the passing of the hours.
