## Overview

Located in Iceland's dramatic landscape, "The Ark - Iceland Trekking Cabins" meets the increasing demand for sustainable accommodation tailored to trekkers and nature enthusiasts. The design focuses on modular architecture, emphasizing functional efficiency and environmental integration while ensuring a minimal ecological footprint. The cabins are intended to provide accessible shelter that enhances the outdoor experience.

## Modular Design Efficiency

The project employs a modular system that facilitates rapid assembly and transportation. The design process is streamlined into distinct phases: unit design takes approximately 10 to 15 days, factory assembly is completed in 20 to 30 days, and on-site assembly requires only 1 to 5 days. Helicopters are utilized for the transportation of components, signifying an innovative logistics method suitable for remote locations. The cabins feature interlocking modules characterized by clean lines and a predominantly white façade complemented by wooden vertical slats, fostering visual harmony with the surrounding environment.

## Sustainable Materiality and Functionality

Durable and sustainable materials are central to the design, including concrete for structural stability, engineered wood for warmth, expansive glass surfaces for natural light, and polyethylene for weatherproofing. Additionally, photovoltaic modules are integrated into the roofs to harness solar energy. The interior layout emphasizes functionality, featuring modular sleeping arrangements, utility areas equipped with kitchens and dining spaces, and shared amenities. The adaptability of configurations allows for customization based on the site-specific context and user requirements, further supporting the project's commitment to sustainability and resource efficiency.

`
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.
