This residence is hidden behind the façade, by Baldassarre Longhena, of a 17th-century building overlooking the Rio della Sensa canal in Venice.The apartment occupies two third of the facade while the other third belongs to an other household.The main façade was restored conservatively and is now characterized by an internal glass door, with steel profiles, that connects directly to the living area. A library for the owner’s 10,000 books covers the full height of the wall on the southwest side of the living area.The ground floor is a single open living and dining space. Opposite the garden entrance is a typical Venetian water door; access through a new system of steps allows higher access to the house from the water level and protects it from the tides but also allows water to enter underneath the glass box.A linear stair, made of steel and glass, leads to the upper loft level, constructed of steel, which houses the bedroom and bathroom. The staircase connects to the balcony and to a system of steel and glass catwalks, from which the library can be accessed.
