The project concerns the twentieth century’s building renovation, fitted in a series of buildings arranged in a linear way along a very busy public street. Behind them, narrow and long lots, separate the buildings from the railway.
The renovation and extension project tried to recover the volumetry still avaiable on the lot, adding a new trapeziodal plant volume on the courtyard’s side. So the extension’s shape results from the orientation of the railway’s limit.
The new volume, leaning against the existing one for its entire width, is divided into two levels: the lower one for the kitchen and the living room and the upper one for the bedroom. It’s entirely covered by a flat roof coated with a sheath. A continuous, covered balcony, allows to look at the rear garden.
The new volume, entirely plasterd 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 aluminum, 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.
In the first case the marble strips, separated from the sidewalk by a corten lower band, continue to create a kind of sunbreaker along the single window, canceling in part its presence and restoring continuity to the front. The same marble coating is used to mask metal doors containing gas and electic meters.
The corten coated part also contains the entraces to the dwelling and to the box. Their presence is canceled by the cladding wich, extending over the entire front, masks the backing on the upper flooor. This coating is anchored to a substructure made of omega strips obtained by bending the same two-millimeter corten sheet, used for the front. The handle of the entrace door is retrieved in the thickness of the covering.
The cornice, which covers both fronts, is also coated in anodized aluminium sheets, which highlights the materical difference reflecting the color of the two front. A continuous aluminum band masks the gutter channel which is encased inside the corince.
The result of this coating operation is the realization of a completely enclosed exterior front, a kind of bunker through which to protect from the outside, creating a safe place to find shelter.
