05
The viewing tower serves as a prominent visible landmark from afar.

The project at Grjótagjá Caves in northern Iceland is located near Lake Mývatn, an area famous for its geothermal hot springs. It includes a visitor center and a viewing tower, designed to handle the increasing number of tourists while focusing on sustainability and environmental protection. The overall design aims to create a strong connection between visitors and the unique natural landscape, allowing for an enriching experience in this distinctive setting.

Design Intent

The goal is to respond to the special topography of the site with architecture that feels both appropriate and engaging. The viewing tower functions as both a landmark and an observation point, providing a wide view of the geothermal scenery. Its careful positioning allows visitors to appreciate the surrounding environment without causing harm to the delicate landscape.

Material Choices

Glass is the primary material used in both the visitor center and the viewing tower. This choice enhances transparency, allowing for clear views and abundant natural light. The glass panels help the structures blend with their surroundings, allowing visitors to feel surrounded by nature. This design choice invites people to engage with the environment while enjoying the comfort of enclosed spaces.

Spatial Configuration

The interior spaces of the visitor center and viewing tower are crafted to maximize light and views. This layout encourages visitors to look out and explore the unique geothermal features of the area. The visitor center includes facilities such as a café and informational displays to support the visitor experience. Each space has been designed to invite people to learn more about the natural wonders they see.

Pathway Integration

Elevated pathways guide visitors throughout the site, ensuring their safety while protecting the local environment. These paths are well-lit and carefully placed, making it easy to move between the structures. They enhance the overall experience by allowing for safe and enjoyable access to the beautiful landscape, reinforcing the connection between architecture and nature.

The viewing tower culminates in a wide platform that offers a complete view of the remarkable geothermal landscape, allowing visitors to take in the beauty of the natural formations and the dynamic interplay of light and water.

`
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.
