## Overview

Located in Iceland's rugged terrain, the PEAK project is designed as a mobile cabin tailored for trekkers, emphasizing landscape integration and sustainability. The intent is to enhance the outdoor exploration experience while providing essential living amenities in a minimalist, functional design. The architecture leverages modularity and mobility to accommodate a transient lifestyle, addressing the unique characteristics of the Icelandic environment.

## Spatial Configuration

The cabin's design features a lightweight aluminum frame that supports multiple functions, including sleeping, cooking, and cleaning spaces. This modular setup allows for easy transportation by hikers, enabling the cabin to be relocated across various landscapes, from mountains to glaciers. The adaptable structure promotes not only a nomadic way of living but also minimizes environmental impact, reinforcing an eco-conscious approach to outdoor activities.

## Material Selection and Sustainability

Key materials used in the PEAK project are selected for their functionality and environmental performance. The aluminum frame provides durability and resilience against harsh weather, while flexible canvas walls offer insulation without significant weight. ETFE panels maximize natural light and energy efficiency, and local stones contribute to both structural integrity and aesthetic harmony with the surroundings. Moreover, the cabin is equipped with a rainwater harvesting system and solar panels, underscoring a commitment to sustainable resource management and energy use.

`
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.
