## Overview

Located near the East Glacier of Paldor in Nepal, the shelter addresses the needs of trekkers and guides navigating the Himalayan terrain. Characterized by its resilience against extreme weather and its provision of comfortable accommodations, the design reflects a deep understanding of the challenges posed by high-altitude environments. The placement of the structure at a vital trail intersection emphasizes usability and safety, while fostering social connections among users.

## Spatial Strategy and User Configuration

The building is organized over two levels, each serving distinct functions that support both communal and individual needs. The upper level features eight dormitories, designed for trekkers, as well as a common area that includes a kitchen and living space to facilitate social interactions. Safety is enhanced through well-planned emergency exits and an external staircase. The lower level prioritizes operational efficiency, offering dedicated storage for gear and maintenance supplies, alongside facilities for local guides.

## Materiality and Sustainability

Material selection is integral to the design, with an emphasis on local sourcing to minimize ecological impact. The foundation utilizes local stone for stability, while corrugated iron panels provide structural integrity and thermal efficiency. Internally, oriented strand board offers a practical yet inviting atmosphere, complemented by insulation made from hemp and yarn wool. The incorporation of double-glazed windows contributes to energy efficiency while allowing occupants to engage with the surrounding landscape. Sustainability is further enhanced by solar panels, water conservation systems, and mechanical ventilation, ensuring a responsible approach to energy and resource use.

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.
