The project by Italian architect Raimondo Guidacci concerns a twentieth century’s building renovation. It recovers an existing lot, adding a new trapezoidal volume on the back side. The new volume is divided into two levels: the lower one for the kitchen and the living room and the upper one for the bedroom. The new volume, entirely plastered in white, presents a modern character that contrasts with the surrounding buildings. The full height openings, their size and the insertion of sliding panels in anodized aluminium, further enhanced this contrast.

On the street side, the front, divided exactly in the middle by the downward slope, is coated with two different materials: one part by white marble narrow and long strips, marked horizontally by the deep continuous backing, the other by Corten steel panels arranged with offset joint. The Corten coated part also contains the entrances to the dwelling and to the box. Their presence is cancelled by the cladding which, extending over the entire front, masks the backing on the upper floor.
