The architecture studio A-cero presents one of its last works about a big single-family house. It takes place in the outskirts of Madrid on a 5,000 m2 plot. It is a single storey building and it has a 1,600 m2 built surface.

The first sensation that this house produces when people go into the plot is that the building seems to be hidden between walls and vegetable ramps that extend up to the roof. They are dyed in dark gray and contain, between them, vegetation areas that seem to climb towards the sky. The house´s façade show a spectacular organic view of the whole house and so even the hard shows its most kind face.

The back front of the house is totally opened towards the garden where the lounge, dining room, library, study and bedrooms are. In this façade the wide windows, the volumes set and the projections (made of concrete too enhance. These elements cover the several house´s porches. The large window of the main lounge hides itself automatically in order to make this stay completely opened to the exterior areas.

The plot includes also an elegant garden, a small lake and a padel track.

The ecological aspect is very in this A-cero´s work: the façade and the roof have the main ecological roles because they are covered with low consume vegetation. Furthermore on the house´s roof has been implemented a renewable energy system made of wide surfaces with solar tubular collectors who allow that the energy autonomy of the house.

    I think there are some very strong lines in the floorplan that make up the “front” (literally) of the house. They make a very powerful statement, like knife cuts in the surroundings; either scaring away unwelcome passers by or opening up towards visitors.

    But I do not get the same feeling from the open backside of the building. At least not from these pictures.

    The two sides seem like two very different ideas, joint like siamese twins by the hint at an underground bunker.

    Well the project seems very well executed, but I think there are to many lines in the kitchen. In such a small space having the range/island, the hood, one of the countertops, and the dining table creating multiple opposing lines is a bit distracting.

    I really like the individual spaces as pictured. Well done aesthetically, and a good atmosphere. Overall though, the building seems a bit labyrinthine and not very cohesive. The exterior seems harsh and sharp, almost the exact opposite of the pictured interior spaces. Overall a good project IMO, but a bit overly large.
