House X by Bojaus Arquitectura: A Harmonious Integration with Nature in Valdemorillo, Spain

Located in the picturesque town of Valdemorillo, Spain, House X by Bojaus Arquitectura is a striking example of modern architecture that seamlessly blends with its natural surroundings. Completed in 2024, this 190 m² residence is a thoughtful exploration of how contemporary homes can harmonize with rugged landscapes while prioritizing durability, sustainability, and timeless design.

Design Philosophy: Building “Of” the Landscape

House X emerges from the delicate balance between human habitation and the raw beauty of the natural environment. Rather than imposing itself onto the terrain, the home is conceived as an extension “of” the landscape, drawing inspiration from historical fortresses and traditional homes such as the houses of Monsanto in Portugal. Its design emphasizes radical integration with nature, creating a dwelling that feels intrinsic to the surrounding environment.

Site Context and Architectural Response

Perched on gently sloping rocky terrain, the site is defined by the presence of a centenary oak, clusters of holm and cork oaks, and scattered granite boulders. Bojaus Arquitectura’s solution was a distinctive X-shaped layout, designed to nestle the house within these natural elements while framing dramatic views from the interior. This careful positioning allows the home to engage with the landscape visually and spatially, creating intimate connections with its surroundings. The architects also drew inspiration from the Ugalde House by Coderch, adapting strategies for harmony with the rugged topography.

Materiality and Sustainability

Durability and longevity are central to House X’s design. Constructed entirely from on-site poured concrete with local aggregates, the home emphasizes permanence over fleeting trends in sustainability. The 50 cm-thick walls, built in handcrafted layers of 60 cm with integrated insulation, ensure thermal efficiency and structural resilience. These robust walls remain exposed both internally and externally, establishing a raw, textural quality that echoes the natural stone of the site.

House X is not just a home; it is built to last generations, standing resilient against time much like the surrounding granite boulders and ancient trees. This approach shifts the conversation from short-term sustainability to long-term ecological and architectural responsibility.

House X by Bojaus Arquitectura is a masterclass in integrating modern residential architecture with nature. Its X-shaped form, concrete construction, and sensitive siting showcase how a home can coexist with and celebrate its environment. More than a structure, it is a permanent dialogue between architecture and landscape, demonstrating the enduring value of thoughtful design.
