### Overview
Located near Paldor Peak in Nepal, the Himalayan Mountain Hut, known as "Mountain Hive," is a sustainable architectural solution tailored for the rigors of high-altitude environments. Designed to accommodate climbers and trekkers, the project emphasizes minimizing environmental impact while providing essential services and shelter.

### Spatial Strategy
The structure features a modular system composed of hexagonal units, offering flexibility to cater to varying occupant needs. Each module serves distinct functions, such as bedrooms, kitchens, and service areas, fostering a communal living environment through interconnected spaces. This layout is crafted to balance privacy and social interaction, encouraging a sense of community among users.

### Materiality and Sustainability
Carefully selected materials contribute to the hut's functional efficiency and sustainability. The lightweight aluminum façade and renewable wood structure are engineered for durability in harsh weather conditions, while cork insulation enhances thermal performance. Additionally, the integration of a photovoltaic roof underscores a commitment to renewable energy, ensuring that the facility operates with minimal emissions. The overall design focuses on recyclability, aiming to significantly reduce the carbon footprint associated with mountain construction projects.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
