The Grjótagjá Tower is situated in Iceland, designed to enhance the experience of visitors exploring the unique landscape of the Silfra fissure and the Mid-Atlantic Ridge. The structure serves as a tourist facility that merges contemporary design with elements inspired by traditional Icelandic architecture. The primary goal is to create a building that fits comfortably within its surroundings while offering safe avenues for exploration.

Design Concept

The design emphasizes a vertical form that stands out against the flat lines of the fissure ridge. This choice of form not only increases the building’s visibility but also provides a meaningful reference point for those navigating the rugged terrain. By adapting local architectural styles into a modern context, the tower connects visitors to Iceland's distinctive natural heritage while making a statement against the backdrop of dramatic landscapes.

Visitor Experience

Careful consideration has been given to the layout, which includes well-placed public spaces and observation points for safe viewing of the nearby caves. These observation plates are essential for enhancing the visitor experience, allowing people to appreciate the geological formations without causing harm. The entrances to both Karlagjá and Kvennagjá caves are designed to facilitate easy access, directing traffic while ensuring that safety remains a priority.

Material Selection

For construction, the tower utilizes timber beams and stone walls sourced from the local environment. This choice helps reduce the environmental impact of the project. Using these materials allows the building to blend with its surroundings and reflects a commitment to sustainable practices. The approach not only minimizes the carbon footprint but also reinforces the connection between the built structure and Iceland's natural features.

The Grjótagjá Tower exemplifies how a building can respond thoughtfully to its environment. With its vertical shape and functional design, it invites visitors to explore while respecting the landscape's inherent qualities. The details in its design enrich the experience of those who come to discover the beauty of Iceland's geological formations.

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.
