San House by Amaia Arana Arkitektura: A Harmonious Fusion of Heritage and Minimalism in San Sebastián

Set in the historic heart of San Sebastián, the San House project by amaia arana arkitektura represents a sensitive renovation of a classic 19th-century residence. Located in a building designed during the Ensanche urban expansion by Basque architect Antonio Cortázar, this renovation carefully balances architectural heritage with modern minimalism.

The original structure, built with a wooden frame and sandstone façades sourced from local Igeldo quarries, is a prominent example of Donostia’s vernacular architecture. After decades of alternate use—including a lengthy period as a medical clinic—this 120 m² apartment has been thoughtfully restored to its original function as a private residence.

Architectural Philosophy: Revealing the Soul of the Space

The goal of the renovation was clear from the outset: to create a bright, spacious, energy-efficient, and accessible home that also respects the history embedded in its walls. The design strategy was to “undress” the structure, exposing and celebrating the building’s original wooden beams, stone walls, and historic elements, all while integrating contemporary comforts.

A powerful duality of old and new emerges. Modern interventions—including flush doors, minimalist baseboards, and handle-free fittings—are visually discreet, allowing the raw materials and existing structure to take center stage.

Interior Design: A Dialogue Between Past and Present

The interior layout is organized around a large, light-filled central space that serves as a kitchen, living, and dining area, thanks to six balconies and a generous viewpoint that opens onto the city’s vibrant streetscape. Each end of the apartment houses a spacious bedroom, while bathrooms and utility areas are tucked toward the interior courtyard.

Custom-designed furniture, including a bespoke kitchen by amaia arana arkitektura (AAA), blends seamlessly with the architectural language of the home. Natural materials like oak wood, marble, and exposed stone combine with carefully planned lighting to create an atmosphere of warmth, tranquility, and timelessness.

Comfort and Efficiency: Subtle Technology for Modern Living

San House sets a high benchmark in energy-efficient renovation. The building envelope has been completely rehabilitated, and an innovative radiant ceiling system by Zehnder was installed. This advanced system offers greater thermal responsiveness and efficiency compared to conventional heating methods, contributing to year-round comfort.

Accessibility was also prioritized. The entry area—once split by a floor level change—now features a gently sloping ramp, ensuring barrier-free movement throughout the apartment.

A Case Study in Thoughtful Urban Renewal

San House is more than just a home—it’s a celebration of historical continuity and architectural innovation. By blending the character of 19th-century Basque architecture with the clean lines and functional ethos of modern design, amaia arana arkitektura has created a space that honors its past while embracing contemporary living standards.

This project is a testament to the idea that sustainable, comfortable, and emotionally resonant architecture is not only possible but necessary in our ever-evolving urban environments.
