Spiralinn is located in the dramatic landscape of Iceland, designed to connect visitors with their surroundings. It functions as a multi-use space that encourages exploration and interaction with the environment. The design focuses on the themes of light and water, creating a structure that allows people to ascend towards the sky or descend into ice caves.

Vertical Movement

The project highlights vertical movement, giving visitors the experience of changing elevations within the building. This upward and downward journey mimics the natural geological formations found in Iceland, resembling the rise of a volcano or the fall into an ice cave. Through this design, Spiralinn strengthens the relationship between the architecture and the landscape.

Fluid Design Forms

The building features smooth, curved forms that reflect the movement of water and the natural shapes of the surrounding environment. These ribbon-like structures blend with the landscape and promote a connection between the built space and nature. Ample natural light pours into the interiors, enriching the experience for those who enter.

Architectural Elements

A key feature of Spiralinn is the glass bridge that crosses the fissure, allowing visitors to traverse safely while enjoying views of the landscape. This design not only serves its purpose as a pathway but also connects different areas of the tower visually. The main tower is positioned within the slope of the fissure, ensuring stability while guiding visitors downward to the ice caves.

Sustainable Integration

Sustainability is a significant aspect of the project. Geothermal heating systems are implemented to reduce energy use in the cold climate of Iceland. This heating ensures a comfortable environment for visitors, particularly during winter months. Additionally, the green roof absorbs rainwater and helps regulate temperature, promoting environmental responsibility.

The interior spaces utilize locally sourced hardwood and basalt stone, enhancing the connection to Iceland's natural landscape. The warm, muted tones create an inviting atmosphere, allowing visitors to appreciate the surroundings as they move through the building.

`
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.
