### Project Overview
Located in arid and semi-arid regions, the design of « L'escargot» responds to the urgent need for sustainable housing solutions amidst the challenges posed by climate change. Developed by architects Alain Briost and Luc Pecourt, this project presents a prototype for versatile living environments in areas where traditional shelters may not provide adequate protection or resources. The design takes into account the pressing issues of population displacement and resource scarcity, creating a framework for innovative, climate-responsive habitation.

### Architectural Form and Materiality
The structure of « L'escargot» features a geodesic dome that combines aesthetic appeal with functional durability. Key materials comprise insulated sandwich panels that ensure thermal efficiency, aluminum for structural and heating applications, and prefabricated floor panels that provide lightweight stability. Textile fog nets are incorporated into the design to capture atmospheric moisture, establishing a critical water collection system suited for challenging climates. The exterior presents a mix of reflective and matte finishes with adjustable sun shading, while the interior space emphasizes utility and comfort, with carefully arranged areas for living, cooking, and relaxation.

### Sustainable Systems and Spatial Strategy
The project integrates advanced sustainable technologies, including a specialized water tank and fog nets that support self-sufficient water production. Renewable energy sources, such as solar panels and a wind turbine, contribute to the habitat’s electricity needs. Additionally, the design features a dry toilet and composting system, effectively recycling waste into nutrient-rich fertilizer for a garden. Internally, the modular spatial arrangement promotes communal living, with open spaces highlighted by large windows that enhance connection to the surrounding landscape. Multi-purpose furniture and retractable storage solutions maximize functionality while maintaining a minimal footprint, reinforcing the habitat's adaptability and emphasis on efficient use of resources.

`
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.
