Positioned between two tectonic plates, the pinnacle serves as a geological observation point that evolves over time, connecting visitors to the dynamic landscape while offering educational and recreational spaces.
5 key facts about this project
01
Pinnacle positioned between tectonic plates to reflect geological movement.
02
Integrated visitor center designed for educational engagement with the landscape.
03
Structure intended to evolve over time as geological cracks expand.
04
Features an observation area that enhances views of Iceland's distinctive geology.
05
Concept emphasizes the relationship between built form and natural processes.

The design is located in Iceland, where two tectonic plates, the North American Plate and the Eurasian Plate, meet. This rare geographical setting allows for a unique interaction with geological features. The concept centers around a structure described as a "pinnacle that responds to the earth." It serves not only as a visual landmark but also as a place where visitors can connect with the natural landscape and learn about the geological significance of the area.

Functionality and Space Allocation

The structure is designed to include several functional areas, such as a museum, a café, a waiting room, and a visitor center. Each of these spaces is meant to enhance the experience for those visiting. The museum provides educational insights into the region's geology, while the café and waiting room offer comfort and hospitality. These spaces work together to create an inviting environment that encourages people to engage with both the architecture and the surrounding landscape.

Transformation Over Time

An interesting aspect of the design is its planned evolution over time. The pinnacle is intended to change as the geological cracks widen over thousands of years. This idea highlights how architecture can respond to natural processes. The structure may eventually become a bridge connecting the two tectonic plates, illustrating the ongoing movement of the Earth. This concept of transformation emphasizes that buildings can adapt and coexist with their natural surroundings.

Geological and Architectural Integration

The design takes into account the specific geological features of Iceland. By strategically positioning itself between the tectonic plates, the structure aims to create a connection between the built environment and the landscape. This relationship serves to enhance understanding of the natural world. The architecture becomes a point of reference, allowing visitors to contemplate the Earth’s natural processes.

Over time, the evolving form of the pinnacle will encourage guests to think about the connection between architecture and geology. It stands as a testament to the forces shaping the land and reflects the relationship between human creation and the planet's history. The design invites visitors to engage with the landscape while also considering how it changes over time.

`
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.
