The building is situated in a recidence area conformed by a low density knitting outsaid Buenos Aires city, in a site between shared walls. The housing is articulated around a central courtyard, the spatial structure puts in coincidence this with the double hight livingroom, giving a privileged ubication with views towards the two gardens around the house. This strategy results in visual connections and spaces between the diferents enviroments in where the domestic life is developed. The ground floor has these spaces destinated to the life in community, the study, the livingroom, the diningroom and the kitchen. Upstairs there are arranged the spaces that require more privacity, the bedrooms. A corridor that cross the large air volume of livingroom connects the main bedroom and the terrace with the children's bedrooms. The windows and the circulations are arranged with the objective of setting transparencies and connections with the exterior. The proyect addresses the issue of the courtyard, the emptiness produces a movement that essentially belongs to the architecture reasons. It is an active emptiness, intersected by the light, an emptiness to delicately give organized tension.
