Located in a pleasant residential neighbourhood, the house is a compact building (almost a cube) surrounded by a 3 meters wide perimeter indispensable courtyard, which is the minimum mandatory gap based on current regulations.The pre-existing yard, the swimming-pool and the shed set at the back of the plot are preserved by express wish of the owners. The perimeter courtyard, which completely surrounds the whole house, functions as an outside lounge which is connected in different ways and intensities with any (interior) pieces of the ground floor, giving them different qualities and uses on each façade: on the south, a sunny garden is connected to the kitchen; on the west, the main entrance; on the east, an uncovered parking place from where to access to the kitchen; finally, on the north, a large terrace links the house to the upper garden with the pre-existing swimming pool.All the courtyard elements (fences, pavements, benches, etc.) are built of a unique material working as a whole. Vegetation will finally stamp in time the ambience and character pretended. The house and the courtyard are made of black concrete block, a material that resolves both the loadbearing wall structure and the façades. The block is shown inside and outside the house. The courtyard pavements and walls are also built of black concrete block as well.The structure of the house is a load-bearing wall system with three concentric walls, one wall for each floor, subjected under compression only. So, the inner wall ends at the ground floor level, the intermediate wall ends at the first floor and the façade wall arrives at the roof floor. Inside the house, at the main rooms, the concrete block walls aren’t covered.For the stairs pavement we used recycled hydraulic tiles coming from the old house of the plot. Underneath the stairs, where the block walls are wider (30cm), a central fire place faces the living room and the kitchen too.
