This small penthouse that was located in the attic of a house between party walls in the reticular mountain village, enjoyed spectacular views towards the Sierra de Grazalema thanks to the use in height by the abrupt slope of the urban nucleus. The small space was in structures taking advantage of the inclined roof, serving as a storage loft, with access through linear concrete stairs.

On the structure this space under cover is adapted and, respecting the existing courtyards, the volume built on the large flat roof in disuse of the building is extended. The lower deck is used to locate the storage area, laundry (in the area with lower height), as well as bathroom, living room and secondary bedroom. The extension, according to the demanding urban parameters, will serve to add the master bedroom and the kitchen, both linked with the rest of the terrace.

In the interior design has opted for warm materials in flooring, such as wooden parquet and WPC on the outdoor terrace, leaving the rest of the walls in white texture to provide greater lighting and spaciousness, highlighting precisely the red lines that give some uniformity and continuity to the spaces, open and functional, accentuating them with LED lights that serve to create a light that is indirect and pleasant to the interior environment. The red, used both indoors and outdoors is a color that, according to the traditional roofs of the white villages of the Sierra de Cadiz, accentuates and dynamizes the spaces, highlighting volumetric and compositional elements that give coherence and homogeneity to the work.

The volumes conform to the existing courtyards to create independent spaces interconnected by a longitudinal axis. These are raised with a minimum height and a fragmentation of holes analysed according to the perspectives that from the inside is the privileged natural environment and the silhouette of the Cadiz mountain range. This formal outline is underlined in red (colour of the traditional roofs) providing the interiors with optimal lighting and landscape integration.

The non-linear language of the holes arises from the analysis of the territory where the building is inserted, as a symbiosis between the strict grid of 18th century urbanism and the organization of the abrupt surrounding mountain landscape. The enlarged volumes are therefore perforated by irregular holes traced according to the views to the outside from the interior spaces of the penthouse.

This same line leads to interior elements such as shelves, with artificial lighting, which together with the works of local artist José Hinojo, create a unique and stimulating atmosphere. The expanded roof is filled with photovoltaic panels that make the house self-sufficient energetically. Constructively the details are taken care of with glass railings, covered on plots, linear lighting, local materials, high performance carpentry, efficient installations, for optimisation of energy efficiency and better architectural integration of the whole.

For lighting, linear LED lights are chosen, highlighting compositional aspects of the spaces, being diffuse and warm for the environment where we are. Internally, the works of the aforementioned local contemporary artist are placed in the various rooms of the house. The kitchen, linear and white, is integrated as a service wall to relieve the central communication spaces. In the furniture used, we choose a sofa also intense red, and more traditional and local materials such as wood or leather for tables and chairs.

In the use of carpentry, hidden doors and folding beds used in the secondary room, make the house more versatile, using, for example, this space as a single bedroom, double bedroom, play space or work space.
