House X | Luis AsnHouse X challenges conventional notions of contextual integration by asserting its presence in the rugged landscape of the Serrana de Cuenca. Rather than aiming for a delicate, reversible footprint, it embraces a paradoxical approach: its form is invasive, yet its material strategy is one of deep assimilation. Unlike contemporary projects prioritizing ephemeral sustainability, House X advocates for permanence as a more responsible architectural response.House X Technical InformationArchitects1-6: BojausLocation: Serrana de Cuenca, Valdemorillo, SpainGroos Area: 190 m2 | 2,045 Sq.

These references are not superficial but guide the houses articulation of mass, texture, and endurance. The designs engagement with the site extends beyond visual mimicry, opting for an aggressive yet symbiotic relationship with its surroundings.House X employs fragmentation as a spatial strategy, using its X-shaped plan to establish a series of dynamic interactions between solid and void, shelter and exposure. The four wings of the house extend outward from a central nexus, each oriented toward a specific natural feature. This layout ensures a multiplicity of perspectives, emphasizing the changing qualities of the landscape throughout the day.The projects sectional complexity reinforces its architectural intent. Heavy concrete walls form deep recesses that control light penetration, creating moments of contrast between the structures solid mass and the ephemeral qualities of natural illumination. Interior spaces are defined by their relationship to framed openings, emphasizing a dialogue between enclosure and outward extension.A clear influence can be traced to the Ugalde House by Jos Antonio Coderch, particularly in its approach to organizing space in relation to the site. Like Coderchs work, House X does not treat architecture as an isolated object but rather as a device that mediates between inhabitant and landscape. The way spaces unfoldvisually and experientiallyunderscores an architectural philosophy that prioritizes spatial richness over formal spectacle.House X Materiality and Construction ProcessMateriality is central to House Xs identity. Constructed entirely from on-site concrete with local aggregates, the house asserts a tectonic connection to its environment. The 50 cm thick walls, hand-formed in 60 cm high layers, incorporate insulation between the inner and outer concrete layers, ensuring structural robustness and thermal performance. This process results in a distinctive surface texture where large embedded stones remain visible, reinforcing the material dialogue between the house and its geological surroundings.The interior material palette maintains this focus on tactile contrast. Exposed concrete ceilings and walls are softened by the integration of oak flooring and walnut cabinetry, offering a counterpoint to the otherwise austere composition. The careful juxtaposition of raw and refined materials heightens the sensory experience of the space, encouraging an engagement with texture and temperature.The houses longevity is embedded in its construction methodology. In contrast to architectural trends that emphasize lightness and reversibility, House X makes a case for durability as a form of sustainability. By employing materials and techniques that promote extended lifespans, the project critiques the disposability inherent in much contemporary sustainable discourse. Rather than focusing on rapid assembly and eventual disassembly, it proposes an alternative paradigmone in which architecture is built to endure, evolving with its environment rather than yielding to it.Broader Architectural and Cultural ImplicationsHouse X raises critical questions about architectures role in shaping its context. Its refusal to dissolve into the landscape challenges the prevailing ethos of passive environmental integration, suggesting instead that architecture can exist in a state of productive tension with its surroundings. This approach disrupts the assumption that sustainability must be equated with impermanence, arguing instead for an architecture of lasting material and spatial integrity.The projects stance on sustainability is particularly noteworthy. It critiques the industrys tendency to prioritize symbolic gestures over substantive material strategies. In an era where sustainability is often reduced to technological solutions or superficial ecological aesthetics, House X proposes a different trajectory that values endurance, resource efficiency, and site-specific adaptation as the foundations of sustainable design.Furthermore, House X can be seen as a contemporary reinterpretation of Brutalism. Its unapologetic use of concrete, emphasis on mass and texture, and resistance to transience position it within a lineage of architecture that prioritizes raw materiality and structural honesty. However, unlike the monumental Brutalist projects of the 20th century, House X refines this language through a more nuanced understanding of context, craft, and environmental responsiveness.House X Plans Bojaus Arquitectura Bojaus Arquitectura Bojaus Arquitectura Bojaus Arquitectura Bojaus ArquitecturaHouse X Image GalleryAbout Bojaus ArquitecturaBojaus Arquitectura is a Madrid-based architecture studio founded in 2012 by Ignacio Senra and Elisa Sequeros.
