The rotation of the travertine wall filled with transparent resin intends to ennoble the entrance area and connect it visually to the light coming from the living area. At the same time, it allows for a perspective artifact that makes it visually larger and well proportioned in the entrance path to the house. The resulting trapezoidal shape, also marked by the different texture of the wooden floor, is used in other forms and furnishings of the apartment. The bookcase, the plastic backdrop of the living room, is shaped like a trilite detached from the wall that shows a formal abstraction of a structural archetype. The use of travertine, in this case brushed, is replicated in the main bath as a shaped ribbon connecting the sink and shower area with a unic shape embedded in the regular texture of the dark gres big format tile.
