Emerging from the rift of tectonic plates, a tower constructed with steel columns seamlessly integrates into Iceland's dramatic landscape, providing essential services for visitors to explore the region's geothermal features.
5 key facts about this project
01
Observation tower symbolizes the tectonic activity between the Eurasian and North American plates.
02
Constructed from steel pipe columns that reflect the site's geological themes.
03
Designed as an underground structure to minimize visual impact on the landscape.
04
Facilitates access to nearby geothermal bathing caves and natural paths.
05
Encourages visitor engagement with the unique geological features of Iceland.

The Grounded Tower at Grjótagjá is located in a region of Iceland characterized by its active geology. Positioned on the North American side of the rift formed by the separating tectonic plates, it provides a space for visitors to engage with the area's geothermal features. The design emphasizes harmony between the natural landscape and human activity while offering practical facilities like a café, visitor center, and office areas for exploring the site.

Design Integration

The project comprises four underground structures that work together to facilitate visitor movement and access to bathing caves. This arrangement allows for easy navigation while promoting an appreciation of the surrounding environment. The careful layout encourages exploration and rest, serving both practical needs and environmental respect.

Observation Tower

A notable feature of the design is the observation tower. It stands as a focal point for visitors seeking to view the nearby mountains and the Hverfjall Crater. This structure functions as a viewing platform while also symbolizing the geological forces at play in the area. It represents the interaction between the Eurasian and North American plates, offering a blend of utility and interpretation of natural phenomena.

Structural Composition

The tower is constructed using steel pipe columns that converge, embodying the tension created by tectonic movements. This choice of materials not only reinforces the geological narrative but also contributes to a strong visual presence in the landscape. The arrangement of the elements enhances the relationship between architecture and nature, creating an experience that is both informative and engaging.

The design reflects an understanding of the site's geology, drawing connections between the buildings and the natural surroundings. It provides essential visitor facilities while remaining sensitive to the environmental context. This balance enriches the experience for those who interact with the captivating landscape of Grjótagjá.

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.
