Detached house of new building in Sant Cugat of the Vallès, of ground floor and floor, in a volumetric unitary set, shed roof, executed with a single material in all the blind part of its skin - façade and roof-. With a program destined for an only user -but with capacity for 6 people- the dimensions of the building are generous in relation to the plot, exhausting the allowed occupation. Hence the main objective of the project: the search of the privacy in relation to the strong visual and acustic impact of the neighbouring buildings and the adjacent Carretera de Vallvidrera. Thus, inner courtyards are incorporated for the delivery of natural light and ventilation to the rooms, while they keep isolated from the neighbours. In addition, the premise of the security is key in creating some sliding frames forming part of the volume created and that will maintain the use and enjoyment of the porch and courtyards once closed.
