Forestón Cabin: Architectural Design Integrating Sustainability and Local Materials in a Mountain Environment
Integration of Design with Nature in the Pyrenees
Forestón Cabin is situated in the heart of the Pyrenees, where forests, rocks, and climatic conditions govern their own quiet laws. The cabin appears as a natural part of the landscape, more akin to a geological event than a conventional building. Covering no more than 20 square meters, this wooden dwelling does not seek to stand out or announce itself; rather, it gives the impression of having always existed, a solid entity that emerged from the mountain long before it was named or defined.
A Sustainable Architectural Approach
The cabin’s design and construction reflect a commitment to environmental architecture and sustainable building, with a focus on using locally sourced timber from surrounding forests. The project also embodies the concept of regenerative forestry, carefully integrating natural resources efficiently across all construction layers, highlighting the symbiotic relationship between humans and the environment.
Educational and Architectural Experimentation
The cabin also serves as an educational experiment, implemented by a cohort from the Master’s program in Environmental Architecture and Advanced Construction as a practical case study for applying principles of sustainability and architecture in harmony with nature. This experiment demonstrates how small-scale projects can offer innovative and sustainable solutions without relying on large or conventional architectural designs.
Integration of Interior Functions with Design
The cabin is situated on a sloped plot near a mountain lodge at the MónNatura Sort site, designed to accommodate two people in a practical and efficient manner. The layout integrates the sleeping area, workspace, and bathroom within a carefully compact interior, adhering to the principle of “nothing in excess.” Every surface, corner, and opening serves a specific function, reflecting meticulous attention to efficiency and optimal space utilization.
Design Response to the Landscape
The cabin’s form is directly inspired by the surrounding landscape. Its multifaceted geometry, composed of angled walls and roofs, interacts with sunlight exposure and climatic conditions to serve the interior functions perfectly. Changes in ceiling heights subtly define different zones within the dwelling, while carefully framed openings provide views of the Pyrenees and allow for cross-ventilation, enhancing natural comfort.
Enhancing Sustainability Through Light Control
Light control plays a central role in the cabin experience. Movable wooden shutters close at night, creating complete darkness that reduces light pollution and supports astronomical activities on-site. This practice emphasizes that sustainability is not only about the materials used but also about knowing when human activity should pause and light should vanish, minimizing environmental impact.
Wood Reinforcement Techniques and Their Environmental Significance
The cabin’s exterior is clad with pine boards featuring natural edges, treated with heat using a traditional Japanese technique known as Yakisugi or Shou Sugi Ban. This process, carried out by the students themselves, provides the wood with natural resistance to insects, water, mold, and fire. Moreover, the technique carries a symbolic dimension: fire has long been an essential part of forest management in the Pyrenees, and the region’s name partly derives from the Greek word pyros, meaning fire. Here, fire becomes both a protective tool and a historical narrative.
Integration of Structure and Furniture
Inside, the cabin transforms into a fully integrated wooden environment. Custom-designed CLT elements not only form the structural framework but also incorporate furniture such as beds, seating, storage areas, and the washbasin table. All these components were fabricated in educational laboratories, creating a unified material link between architecture, structure, and furniture. This approach reflects a hands-on philosophy where making is an inseparable part of the design process, emphasizing the integration of function, aesthetics, and sustainability.
Local and Traditional Craft Materials
The cabin’s material use goes beyond wood to include local and traditional craft elements. During the wool festival in the nearby town of Sort, students collaborated with local farmers to collect sheep’s wool, which was later transformed into felt for making blankets, rugs, and pillowcases. These materials brought warmth and softness to the interior while connecting the project to local agricultural cycles, providing a comprehensive educational experience bridging architecture and traditional crafts. Additionally, a stone sourced from the surrounding environment was hand-carved into a washbasin, turning a natural element into part of the daily ritual of the dwelling.
A Flexible and Sustainable Prototype
From the outset, the cabin was designed as a prototype that allows experimentation and adaptation. It relies on a modular CLT system and dry-assembly methods, alongside a focus on local materials, facilitating disassembly or replication with minimal environmental impact. In this way, the cabin goes beyond its role as a shelter to become a model for sustainable forest housing, connecting education, craftsmanship, and environmental stewardship.
Rethinking the Relationship with Forests
With the cabin open to visitors, it offers a practical model for rethinking forests, not merely as a resource to exploit but as ecosystems to engage with thoughtfully and respectfully. The cabin exemplifies how design, materials, education, and craftsmanship can be integrated into a single experience, demonstrating that sustainable housing can be both responsive to nature and contributive to environmental protection.
✦ ArchUp Editorial Insight
Forestón Cabin provides a practical model for understanding the relationship between architectural design and the natural environment, reflecting an experimental approach through the use of local materials and sustainable practices that can be analyzed and further developed. On the positive side, the project demonstrates how small-scale architecture can interact seamlessly with the landscape and offer a tangible educational experience for students and practitioners.
However, certain aspects remain limited from the perspective of practical architecture and future scalability. The model’s reliance on a very small footprint and highly specific materials makes it difficult to apply the same methods to larger projects or different environments. Moreover, the focus on educational experimentation may reduce the cabin’s suitability for broader practical use. Additionally, the project depends heavily on advanced skills and techniques that are not easily accessible to all architectural teams, potentially limiting its replicability or transferability.
Nonetheless, the model can serve as an inspirational resource in the fields of sustainability, educational experimentation, and efficient small-space design. Architects can study how to integrate local materials and environmentally conscious approaches into their own projects, adjusting the scope of application according to project requirements and local context. In this way, the project gains greater value as an educational and analytical tool rather than a ready-made architectural solution for direct implementation.

Technical Analysis of the Environmental Cabin:
This article provides a technical analysis of the Forestone Cabin as a case study in integrating sustainability, local materials, and applied architectural education.
The cabin is located in the Pyrenees mountains on a sloped plot near the MónNatura Sort lodge, with a total area not exceeding 20 square meters. Designed as accommodation for two people, it was executed by a cohort of the Master’s program in Environmental Architecture and Advanced Construction (IAAC).
The structure is based on a modular Cross-Laminated Timber (CLT) system and dry assembly methods, facilitating disassembly and reuse. External facades are clad with pine panels treated using the traditional “Yakisugi” technique.
