Elevated bamboo structures and translucent fabric create a modular shelter designed for climbers in the harsh environments of high-altitude terrain, ensuring a resilient and adaptable refuge.
5 key facts about this project
01
Translucent fabric façade allows natural light while providing weather protection.
02
Modular design enables quick reconfiguration for varying group sizes.
03
Elevated bamboo framework reduces environmental impact and enhances airflow.
04
Integrated solar panels support energy self-sufficiency in remote locations.
05
Emergency signaling features enhance safety for users in isolated terrains.

**Overview**

The Balloon Hut project is an architectural response to the unique challenges of high-altitude living in Nepal, particularly around the base camps of prominent peaks like Mount Everest. The design prioritizes functionality and sustainability, addressing the needs of climbers and trekkers who require reliable shelter in harsh conditions. By incorporating local materials and contemporary design techniques, the project creates a space that merges traditional and modern architectural practices, aiming to minimize ecological disturbance while enhancing user experience.

**Spatial Strategy and Adaptability**

The design features a modular system of huts that adapt to the diverse requirements of occupants. Each hut is characterized by its circular, dome-like structure, which follows the contours of the terrain, ensuring minimal disruption to the landscape. Elevated platforms constructed from bamboo provide structural support while fostering natural airflow underneath. The interiors are configured to accommodate various functions—dining, socializing, and resting—through flexible fabric systems that allow for easy reconfiguration based on user preferences and environmental conditions. This adaptability is essential in mountainous regions where weather and occupancy needs are unpredictable.

**Materiality and Sustainability**

The Balloon Hut employs a selection of materials aimed at achieving structural integrity and energy efficiency. Bamboo serves as the primary structural element due to its lightweight and durable properties, facilitating mobility and installation. The use of translucent waterproof fabric promotes natural light entry while providing insulation and protection from the elements. Integrated solar panels contribute to energy self-sufficiency, while thermal panels optimize heating and reduce reliance on conventional power sources. Additionally, water tanks capture and store meltwater, further emphasizing the design’s commitment to sustainability and resource conservation. The conscientious selection of materials not only supports the structure’s functionality but also reflects an alignment with local environmental practices.

`
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.
