The building is inspired by the traditional Casa-Patio (courtyard house). It is enclosed by a fenced Wall as if it were a medieval Wall genearatin an introspective space. Three courtyards (entrance, day area and sleeping area) organize the interior disposition of the building in the plot site in the shape of a T. The one-story building is organized in three zones, joined by a distribuitor in the central area of the T. One in the left longitudinal part with the day dependences, another one in the right longitudinal part where the office is and a third one in the transversal part for the sleeping places. The constructive system is reflected in the exterior with a first layer of plastered walls, over which a structure of wooden beams and joist is supported; they open and compose the elevations. Over the wooden structure a garden roo fis supported with low consuming covering plants that have both an a esthestic and energetic efficiency functions.
