Subscribers only
Interlocked forms representing the North American and Eurasian tectonic plates rise from the Icelandic landscape, offering visitors a unique experience that integrates geological processes with public access to geothermal features.
5 key facts about this project
01
Interlocked shell structures symbolize the North American and Eurasian tectonic plates.
02
Design enhances visitor experiences through pathways that arch over the natural gorge.
03
Architecture seamlessly integrates with the geothermal landscape of the Krafla volcanic system.
04
Caves serve as a critical reference point, shaping the building’s form and spatial organization.
05
Structures respond to the dynamic geological processes occurring in the region.

The design sits within the Krafla volcanic system in North Iceland, a location defined by its unique geology and geothermal activity. It engages with the environment in a thoughtful manner, taking inspiration from the nearby Grjótagjá caves. These caves are characterized by constant geological change, serving as an important point of reference. The project aims to connect human activity with the landscape, reflecting the ongoing tectonic movements that shape the area.

Interlocked Shell Structures

Two shell structures form a central part of the design. These interlocked forms represent the North American and Eurasian tectonic plates, visibly embodying the process of plate divergence. This design choice creates a strong link to the surrounding geology and showcases the relationship between the architecture and the land.



Dynamic Spatial Organization

Access to the project is designed to be both functional and intuitive. Visitors move through the site using a ramp or stairway that gracefully arches over the gorge. This design protects the cave's natural integrity while providing clear views of the landscape. The arrangement of spaces encourages exploration and interaction with the geothermal features, enhancing the experience of the site.



Geological Interaction

The approach taken in the design reflects a clear understanding of Iceland's geology. The forms created mirror the deformation gradients produced by tectonic activity in the region. By doing so, the architecture communicates the natural forces at work while maintaining a connection to the site’s distinctive characteristics. The narrative of geological interaction invites visitors to engage with the land in a meaningful way.



Natural Composition Preservation

A key focus of the design is preserving the natural landscape. The structures are carefully placed to avoid disrupting the stability of the surrounding terrain. This attention to preserving ecological systems shows a commitment to sustainability. The result is an arrangement that respects the volcanic environment while allowing for human engagement with the natural world.



The design ultimately creates an experience that encourages visitors to consider the geological processes that shape the land, fostering a greater appreciation for the unique natural beauty of Iceland.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
