Canarian studio Xstudio was commissioned to design House O, a complete renovation of an old terraced house in the Arenales neighbourhood of Las Palmas de Gran Canaria, Spain.

The project has just received an honourable mention at the APE Grupo Awards, praised for the fresh way in which the space is opened up, and natural light is introduced, thanks to carefully controlled, surgical interventions on the existing structure. A degree of exposed structural integrity and the installation of new systems allow for a deeper understanding of the building's history, which is further enhanced by the use of colour and ceramics.

The design by Xstudio transforms a two-story house with a single southwest-facing facade and a depth of 14 meters into a dark, compartmentalized interior, creating a more open and flexible domestic space, far removed from conventional norms.

The intervention is characterized by its interior bareness, recovering original textures and construction systems to which, like superimposed layers of memory, installations and structural reinforcements are added, leaving everything exposed. The materials used include pine wood for paneling the hallway and concealing the doors to the bedrooms and bathrooms. Natural pine is used for the furniture design, except in the wet areas, which are defined as monochromatic spaces where the textures of the different materials stand out.

Project description by Xstudio

House O addresses the complete renovation of an old single-family house in the central neighborhood of Arenales, in Las Palmas de Gran Canaria. 

The original two-story house, with only one façade, had an excessively compartmentalized and dark interior, slightly mitigated by two patios located in the center of the plot. Additionally, the client requested the removal of the main patio to increase the surface area of the living spaces. 

The project employs a set of strategies, approached individually but complementing each other to transform the house into a more open and flexible domestic space, far from conventionality.

One of the main objectives of the intervention was to bring light into the interior. To achieve this, partitions were removed, existing openings were enlarged, and the idea of the patio was reimagined. Instead of its disappearance, an alternative was proposed, becoming one of the driving forces of the new intervention: a "light crack," a small green buffer serving as the new house's gravitational center and a transition element between public and private uses. This intervention respects the figure of the former patio through a visible structural reinforcement and a large skylight, preserving its original footprint and essentially referring to the void that once existed. 

In this new micro-patio, a large two-meter-diameter oculus connects the garden with the living area, creating a vegetal backdrop within the house. This striking and disruptive opening is complemented by a secondary screen that filters light into the master bedroom, enhancing the theatricality of this space. A new formal language is introduced here, featuring a set of circular perforations of varying scales distributed throughout the house. These perforations increase both light entry and visual connections, establishing new connections in both the plan and section.

Beyond the architectural value that may be found in the original construction, intervening in an old building requires a certain level of respect for the memory of what was built. In this regard, the set of hanging beams defining the structure near the façade is of interest. The presence of these beams is highlighted by presenting a deliberately unfinished interior, with a joint at the bottom of the beams, at a height of 2.50 meters, running around the interior perimeter of the house, establishing the boundary of the new envelope. This level defines the finishing line for added elements such as furniture, doors, and coverings. Above this height, the intervention exposes the interior walls, uncovering original textures and construction systems, to which new layers, including installations and structural reinforcements, are added and left visible. This stripping operation extends to the staircase, which constantly interacts with the rest of the house. 

Materially, pine wood is used to panel the hallway and conceal the doors to bedrooms and bathrooms. Natural pine is also employed for the furniture design, except in wet areas, which are defined as monochromatic spaces where the textures of the various materials stand out.
