Converting a holiday home in Andalusia into a permanent home was the aim of this project by María Acha, creating new spaces of intimacy for family and friends and achieving a home where one can enjoy peace and connection with nature. “The aim was to transform a single-family summer house into a year-round home with new spaces such as a work area, a leisure area for the winter, an exercise room and, above all, optimisation of storage “, explains the interior designer.
The keys to the refurbishment have revolved around the creation of a new, more functional layout, greater integration with the natural surroundings and the choice of natural materials that coexist harmoniously, such as clay, organic linen, oak wood, microcement and ceramics.

María Acha, in collaboration with the architect Alesander Olasagasti and the engineer Diego Rey, has reorganised this two-storey house with a surface area of 285 m2 plus 400 m2 of gardens, redesigning the flow between rooms and improving the connection between the two floors with a new staircase design.”As in all my projects, my main focus has been the exhaustive study of an optimal layout that achieves intuitive transitions and the creation of a concept and a concrete and personalised story” explains the interior designer.
Redesigned main floor
The main floor integrates the outdoor garden with swimming pool, with a large open-plan living-dining room, to enjoy the smell of flowers and the freshness of the wet grass during relaxing moments and after-dinner meals.
The entrance to the dwelling, with an austere chromatic palette in neutral and warm tones inspired in natural materials, places us in front of the living-dining room, the kitchen, which the interior designer has integrated in an isolated manner with a beautiful glazed enclosure, and the circular staircase with a steel body and finished in microcement, the protagonist and central axis of the dwelling, which facilitates the new layout with a sculptural design that takes advantage of the natural light projected from the skylight. The entire floor shares the same flooring and the use of oak wood in volumes and partitions.

Kitchen integrated in the main space
The interior designer designed the first floor to be open-plan, with the kitchen, which enjoys natural light, integrated by means of a glass partition with a double hinged door in lacquered metal to match the oak, which brings light into the entrance, but gives the floor plan centre stage to the living/dining room.
The parallel kitchen design optimises space and generates a very comfortable work circuit, with a floor-to-ceiling front for storage and appliances and another with the water and cooking areas. The worktop and the shelving in natural Blue Roma stone from Brazil, combined with the oak of the cabinets, stand out. “As the first space visible from the entrance, we had to integrate the kitchen furniture into the new architectural concept of the house“, explains María Acha.

Dining room open to the garden
The dining room, open to the outside through sliding doors, displays a very attractive design with a neutral background and furniture of organic shapes in which the curved sofa and armchair by Moroso stand out, following a current trend that breaks the austere linearity of the Nordic style, embracing the softness and comfort of the enveloping shapes, the table with cement finish by Zanotta and the bentwood chairs by Miniforms.

Downstairs, a socialising space for family and friends
On the lower floor, designed with a more social focus, are located the two guest suites, the gym, an open area with lounge, bar and two terraces. In the day area with a large lounge and various social areas for family and friends, different chromatic ranges have been used from the main floor, with colours and textures inspired by nature, but with a more playful approach. “We had long been interested in exploring the possibility of wallpapering the ceilings, but we had to find the perfect room for it. We soon realised that the large living room on the ground floor was the ideal space for it“, explains María Acha.
