Located in a pleasant residential neighbourhood, the house is a compact building - almost a cube - completely surrounded by an essential perimeter 3-metre-wide patio, which is the minimum required separation according to regulations.
The owners wanted to keep the pre-existing garden with pool and shed at the back of the plot.
The perimeter patio, which completely surrounds the house, is like an outdoor room that relates with different intensities to all the (interior) parts of the ground floor, giving different qualities and uses to each façade: to the south, a sunny garden where you can go from the kitchen; to the west, the main entrance; to the east, the uncovered parking with direct access to the kitchen; and to the north, a terrace that connects the house to the highest level of the pre-existing garden and pool.
The elements that make up the patio (fences, pavements, benches, etc.) are worked on homogeneously in order to turn them into a single entity. Over time the vegetation will end up giving it the intended character and atmosphere.
The house and the perimeter patio are built with black concrete block, a material that allows solving both the structure of load-bearing walls and the façade - where the block is left visible from the inside and outside. On the outside, the same black block is also used for the pavements and walls.
The structure of the house is made of load-bearing walls: three concentric walls successively finish each of the three slabs, making them only work in compression. Thus, the innermost wall reaches the sanitary slab, the middle wall supports the slab of the first floor and the outer leaf reaches the last slab, that of the roof.
Inside the house, the block is left visible, unclad, in a large part of the facings of the main pieces.
Recycled pieces of the hydraulic mosaic of the house that formerly occupied the plot are used for the steps of the staircase. Below (the staircase), where the block walls are thicker (30cm), a fireplace opens into the living room and kitchen.
