As a result, there is a pure prism with two floors that offers the day zone in the ground floor and the bedrooms on the first one. The pre-existent solid is ‘perforated’ so as to create different open spaces in the sleeping area. The space open to the first floor terraces becomes a conceptual operation of walls subtraction: a logic opposed to the typical additive system of construction. The sliding panels intensify this ‘lack’ of volume with their cedar wood texture, which is not treated as a contrast with the full white surface. The structure results simple and straightforward, architecturally immediate, but with a decisive and strong form. It offers privacy as well as requires separation from the surroundings. Light is one of the project materials. Although from the outside the building seems to be poorly illuminated, once you are inside, you realize how much attention has been paid so as to have every place filled with natural light. On the ground floor, there are three opening and all of them have overhead light coming from the upstairs bedrooms’ floors. In this floor, there are also four skylights which capture this overhead light.
