A tensegrity tower rises above geothermal springs, connecting visitors to the geological landscape of Iceland through half-buried pavilions and guided pathways.
5 key facts about this project
01
A tensegrity tower symbolizes geological tension between tectonic plates.
02
Half-buried pavilions reduce the visual impact on the landscape.
03
Pathways are illuminated by optical orange beacons for enhanced navigation.
04
Bridges provide elevated views of key geological features.
05
Concrete construction supports durability in a geothermal environment.

The Grjótagjá Tension Viewpoint is located at the intersection of the Eurasian and North American tectonic plates. This site is characterized by its unique geological features and serves as a destination for visitors to connect with nature. The design emphasizes the geological tensions that shape the landscape, utilizing a concept centered around balance and stability. A tensegrity structure is the prominent feature, reflecting the underlying forces that define the area.

Tensegrity Structure

A tensegrity tower forms the main element of the design. This structure represents the equilibrium between opposing forces in the natural world. It is made from rigid components and flexible cables, cleverly arranged to minimize material use yet maintain a sense of stability. This choice highlights the ability of structures to reflect natural conditions, showcasing an innovative approach to architecture.

Visitor Pavilions

Half-buried pavilions are integrated into the landscape, providing necessary facilities like restrooms and a snack bar. These structures blend into the earth, which helps reduce their visibility and environmental impact. Being partially underground not only protects the buildings from the elements but also strengthens their connection to the natural surroundings.

Pathways and Navigation

A system of pathways guides visitors throughout the area, marked by brightly colored beacons. These beacons serve as navigation aids, enhancing visibility during various lighting conditions. The paths create an easy flow across the site, leading visitors to explore key geological features such as the Karlagjá and Kvennagjá caves, and ultimately to the tensegrity tower.

Bridges and Engagement

Connecting elements of the site, bridges facilitate movement and provide unique viewpoints of the geological formations. This aspect of the design encourages visitors to engage with the landscape, allowing them to appreciate the natural beauty from elevated perspectives. The thoughtful arrangement of bridges and pathways enriches the experience of exploration, inviting deeper immersion in the geological narrative.

Concrete is the primary material used in the construction of the visitor pavilions, offering practicality and durability. The straightforward use of this material aligns with the overall design intent, reflecting an approach that is both functional and respectful to the environment.

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.
