The assignment came with two clear conditions from the clients: on one hand the respect and minimum impact on their parents' home, on the other extreme of the plot, in the result and during its construction. On the other hand, a much adjusted budget.
The intervention began with the basic morphology of a house between two party
walls, but with the regulated condition to give the corner to the street and the particularity of having a blind façade oriented to West.
It was important to maximize the garden which would separate the client's and their parent's house, we had to maximize the total legal height and number of floors to reduce the occupation. The solar orientation and the restrictions described above, made us imagine a single South facade as a source of sun caption, entrance, views and natural sunlight... the backyard becomes a hall. The two remaining façades, oriented to the street, would have a closed appearance.
The strategy defines a tall house, with a low occupation, opened through a gallery in its South façade. The structure works as two blind bearing walls and a West facade to use a lighter ceiling in the short direction.
The staircase is located perpendicular to the main party walls, forcing it to become a structural hole. Each half floor height is a programmatic area. The kitchen and living room are in the ground floor as a continuous space and in relation to the exterior. The intermediary height assumes the bathroom and laundry room as the only part of the program strictly closed, whilst the first floor is left as the studio, the programs shared with the family and in between the uses of morning and night. The third floor belongs to the rooms, South for kids, North for parents.
A double façade is given to the Zurbano Street, as a gallery with different proportions in each floor. In the ground floor, the gallery is enlarged to allow the use of a living room in the winter, and a porch in the summer. In the first floor, the gallery is reduced to reinforce its fireplace effect and produce a natural heating or a cross ventilation. The gallery becomes the area for uncovered installations. The proportions of this space, reinforce the thermic inertia of the concrete ceilings. Finally, this section also decreases the visual presence of it from the garden.
The materiality of the house appears as an evidence of the constructive technology being used: brick perforated bearing walls, which will remain seen in the interior. Taking the maximum advantage of the geometry implies the design of a closure without any air chamber to solve the façade with the minimum depth. Therefore, we used an exterior closing such an isolation of fibreboard to finish the three levels of lime mortar and silicate paint, being highly breathable at the same time as isolated and impermeable. The ceilings would the in the shortest direction from one party wall to the other with reinforced concrete beams and ceramic tiles. The concrete floor will result as the 4cm of the compression laver to allow the desired finish.
