The intervention expands a single-family home in Aravaca to create one more floor to introduce a new home.

The renovation consists of making the terrace located on the top floor of the house habitable to house an independent apartment for the family’s son.

The process of creating the new space began with the external appearance of the intervention.

How to crown the previous house, which was made of brick and covered with a lot of vegetation, was the most important thing when starting the design.

To prevent the height of the house from increasing excessively, we chose the domed shape.

This way we were able to reach greater heights inside, giving the space more spatial dignity, and reducing the perception of its height from the outside.

Furthermore, this domed crowning did not compete with the cubic shapes of the rest of the house.

We wanted this new floor to be perceived as a different element, and that is why we chose to use cork.

It also fitted due to its lightness and its insulating properties in contrast to the solidity of the brick of the rest of the home. In addition, for the vault we decided to use zinc.

This whole process went very smoothly with clients willing to do whatever we proposed.

As soon as the creation of the vault arose, and based on the need to prioritize the incredible views from this height, the interior space immediately took shape.

The house has 50m2 on the ground floor where the access, one bedroom and a bathroom are located, and the upper floor with 130m2 divided into two areas: the private area and the public area. The private area has a bedroom and a bathroom.

In the public area, the kitchen, dining room and living room are located in one open room that extends to the outside with large windows to the north.

This space also preserves a large circular skylight that previously illuminated the stairwell, which floods the entire room with light.

The structure of original concrete beams and pillars, which was left exposed, also plays an important role

and contrasts with the new structure of slender circular metal pillars painted sky blue so that they blend with the privileged views of the house.
