Constructed with a raised timber framework and equipped with a rainwater collection system and filtering fabric, the facility provides climbers with essential hygiene solutions in the extreme environment of Mount Everest.
5 key facts about this project
01
Raised structure to reduce wildlife intrusion and enhance user privacy.
02
Equipped with a rack-lever mechanism for vertical adjustment based on snow levels.
03
Built with a rainwater collection system for resource efficiency in an extreme environment.
04
Inspired by traditional Asian temples, blending cultural significance with functionality.
05
Utilizes filtering fabric to purify collected water, integrating sustainability into design.

The WC design proposal addresses the need for a minimum bathroom facility at the base camps along the ascent routes of Mount Everest. Set in one of the world’s toughest environments, this facility aims to provide climbers with a clean and functional space. The overall design emphasizes user safety, privacy, and adaptability, making it fit for the challenges posed by high-altitude expeditions.

Raised Structure

The structure is built on a raised wooden framework, which serves to reduce risks associated with wildlife while ensuring user privacy. This elevation is crucial in extreme climates, where comfort and usability can be affected by external conditions. By providing a secure space, the design promotes hygiene standards that are especially important in remote camping situations.

Innovative Mechanism

A key aspect of the design is the rack-lever mechanism found within the support poles. This mechanism allows the toilet to be adjusted vertically according to changes in snow levels throughout the year. Such flexibility ensures that climbers can rely on the facility, even as environmental conditions shift with the seasons, maintaining usability no matter the weather.

Cultural Integration

Influences from traditional Asian temples are visible in the simplified form of the upper structure. This design connection to a cultural reference adds an appealing visual aspect. Filter flaps made from special filtering fabrics hide a tank that collects rainwater and melted snow, linking the facility to its natural surroundings and encouraging the use of local resources.

Sustainability Focus

Emphasizing sustainability, the design includes a system for rainwater collection, helping to lessen environmental impact. By using resources such as melted snow and rainwater, the facility promotes efficient water usage in a location where these resources may not always be readily available. Wood is used for the construction, providing durability while adhering to environmentally conscious principles.

The simplicity of assembly and disassembly is achieved through a construction system of wooden beams and pillars, making transport and setup straightforward for climbers. This practical approach addresses immediate needs while reflecting a considerate attitude toward infrastructure in demanding environments. It enhances the climbers' overall experience by maintaining essential requirements for hygiene and safety.

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.
