## Project Overview

The Iceland Trekking Cabin, designed by Peder F. Ulven, aims to provide a sustainable accommodation solution for trekkers within Iceland’s rugged landscape. This design is contextualized by the region's volcanic activity, harsh weather conditions, and unique topography, ensuring that the cabin functions effectively as a refuge during adverse climatic events. The use of local materials is a fundamental aspect of the project, aligning with a commitment to sustainability while also enhancing the practicality and comfort for users.

## Material and Structural Strategy

The cabin's construction utilizes local stone, integrated into a wire mesh framework to create reinforced stone cubes that provide both structural integrity and visual harmony with the surrounding environment. Steel beams offer essential support, enabling the cabin to withstand the region's severe weather. Large, triple-glazed windows are strategically placed to optimize natural light and provide expansive views while maintaining energy efficiency. Interior features, such as hammocks that serve as both sleeping and privacy solutions, illustrate a creative approach to spatial organization.

## Functional and Spatial Design

The layout of the cabin is thoughtfully designed to accommodate the needs of trekkers. A central cooking area encourages communal interaction, while flexible leisure spaces promote relaxation after strenuous outdoor activities. The inclusion of shower and sauna facilities addresses wellness needs after trekking, emphasizing a comprehensive user experience. Additionally, effective heating is provided by an efficient fire system, alongside designated storage areas for gear, ensuring both organization and cleanliness. The design also takes into account geographical considerations, strategically positioning the cabin near rivers for easy access to water resources while minimizing the ecological footprint.

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.
