Nestled in San Sebastián, a city on the Northern Coast of Spain, this flat is embedded within the fabric of Gros, a central neighbourhood known for its 1930s expressionist architecture. Originally designed to accommodate large, working-class families, the flat’s layout was once subdivided into numerous small rooms. Our approach sought to reimagine the space, transforming it into a modern, open-plan three-bedroom home with thoughtfully designed living areas.
Minimalist flat in San Sebastian
To achieve this, the majority of internal partitions were removed, leaving the original concrete beams exposed as a nod to the flat’s history and former spatial divisions. The raw, imperfect texture of the beams contrasts with the pure white walls and smooth micro-concrete floors, creating a dialogue of materials that adds depth and character to the interior. By eliminating door frames and skirting boards, natural light is amplified, enhancing the luminous quality of the space during the day and highlighting the natural textures of Carrara marble, linen, and wool.
In the evening, a track lighting system mirrors the horizontal geometry of the concrete beams, offering flexibility to frame the dining area in various configurations. The living space features a discreet workspace concealed behind a large sliding door, positioned to take advantage of the flat’s brightest area. In the kitchen, design gestures are minimal, allowing the materiality of the marble worktop and splashback to take centre stage. Matte Fenix cupboard doors conceal appliances, maintaining a serene and harmonious atmosphere.

EFFICIENCY
External walls, ceilings, and floors were insulated, underfloor heating was upgraded, and windows were replaced to meet the latest energy efficiency standards.
The interplay of pale tones, exposed concrete, and Carrara marble establishes a harmonious balance of materiality and texture, forming a neutral yet tactile canvas for the family’s story to unfold. This transformation not only respects the flat’s historical context but also redefines it as a contemporary, light-filled home that responds to modern living.
The bathroom is clad in large-format tiles, with the bathtub, basins, and light grey cement floor creating a sculptural interplay of intersecting volumes. Throughout the project, energy efficiency was a priority.
