Utilizing burnt wood and a phytopurification system, the design integrates seamlessly into the mountain landscape, offering a functional retreat that promotes sustainability and community engagement.
5 key facts about this project
01
Burnt wood construction enhances durability and aesthetic appeal while blending with the natural landscape.
02
A phytopurification system filters water on-site, promoting sustainable resource management.
03
The design features a geothermal system for energy efficiency, utilizing the earth’s stable temperature.
04
Distinct “masonry shears” provide structural support while allowing for a visually open layout.
05
The layout integrates intimate and communal spaces, encouraging both personal reflection and social interaction.

The project is set in "Vale de Moses," designed to blend into its natural surroundings while functioning as both a retreat and a community space. The overall concept encourages connections between enclosed areas and open spaces. It creates room for quiet reflection as well as community interaction. This relationship with the landscape enhances the user experience and promotes a sense of belonging to the site.

Spatial Organization

The arrangement features distinct layers of space that serve various functions. Key elements include the mountain, the wall, humid rooms, a stove, storage, a kitchen, and a spacious yoga practice area. This layout allows for a journey from private, intimate spaces to larger, communal areas. Such planning thoughtfully balances privacy with opportunities for social engagement.

Structure and Materials

The design shifts from solid walls to a more open layout, using "masonry shears" for structural support. A wooden framework supports this system, offering a visual transition to less weighty roofing. Burnt wood is used throughout, ensuring durability and a pleasing aesthetic that complements the natural setting. This choice highlights both strength and beauty in the construction.

Thermal and Water Systems

The design prioritizes thermal efficiency through various strategies. The walls function as thermal mass, keeping the interior comfortable by moderating temperatures in both summer and winter. A geothermal system is also part of the design, using the earth's steady temperature to assist with heating and cooling. Additionally, a water pond located on site acts as an important part of the project, incorporating a phytopurification system that filters and cleans water, promoting sustainability and responsible resource use.

Building Integration

The concept emphasizes not just the experience of users but also a commitment to environmental care. The building is strategically placed to take advantage of views, creating an engaging experience with the surroundings. The attention to detail, like protective eaves that support ventilation and natural light, reinforces the connection between the structure and the outdoor landscape. Every aspect contributes to a harmonious relationship between built forms and nature.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
