5 key facts about this project
01
Utilizes a sod roof for natural insulation and temperature regulation.
02
Constructed primarily from laminated reclaimed wood, minimizing environmental impact.
03
Features a chimney-effect fireplace for efficient heat distribution within the tower.
04
Rainwater harvesting systems integrated for sustainable water usage.
05

### Overview
Located in the rugged terrain of Iceland, the Sod-Lam Trekking Tower draws inspiration from traditional Icelandic architecture while addressing the challenges of the Arctic environment. The structure prioritizes sustainability and minimal ecological impact, creating a contemporary refuge for trekkers that harmonizes with the landscape. By leveraging local geography and climate considerations, the design promotes a holistic approach to living that reflects both cultural heritage and modern architectural principles.

### Spatial Configuration and Material Innovation
The vertical design of the tower minimizes its land footprint to 120 square feet, thereby protecting the surrounding landscape while maximizing interior space across multiple levels. The structure features a thermal envelope comprised of layers of sod, reaching up to 0.5 meters, which enhances insulation and temperature regulation. This innovative use of earth as a natural insulator aligns with traditional building practices, offering a blend of functionality and environmental sensitivity. The exterior is finished with laminated reclaimed wood, sourced from previous constructions, which not only contributes to its structural integrity but also reduces material waste.

### Sustainability and User Experience
The design incorporates advanced sustainability features, such as geothermal systems and rainwater harvesting, to address energy and water needs effectively. Composting toilets and greywater systems further emphasize resource conservation, exemplifying the commitment to eco-friendly practices. Interior elements, including a fireplace optimized for airflow and heat distribution, enhance user comfort while allowing trekkers to engage with the natural surroundings. The multi-level layout provides panoramic views of Iceland's landscapes, enriching the wilderness experience and encouraging an appreciation for the environment.

`
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.
