Charcoal wood cladding distinguishes a bold structure that frames sweeping views of the Hverfjall volcano and captures the interplay of tectonic plates, serving as an observation platform for visitors to engage with Iceland's unique geological landscape.
5 key facts about this project
01
Charcoal wood cladding complements the volcanic landscape.
02
The elevated boardwalk connects two tectonic plates.
03
A spiral staircase allows for gradual ascent and observation.
04

05
Design integrates educational aspects of geology and nature.

The Iceland Cave Tower is located just north of Hverfjall volcano in Iceland, sitting at the point where the Eurasian and North American tectonic plates converge. This site serves both an educational and recreational purpose. The design aims to celebrate the merging of these continents while respecting and minimizing impact on the natural landscape.

Design Concept

The building's form serves as a visual marker in the rugged landscape. Visitors are welcomed by an elevated boardwalk that connects the two tectonic plates, providing a way to experience the geological features up close. As people walk along this path, they gain a deeper understanding of the landscape and its unique geology.

Interior Experience

Inside the tower, a spiral staircase wraps around a central core, guiding visitors upwards. The design includes resting areas on the way up, allowing individuals to pause and take in the view. At the top, the opening offers expansive views of the tectonic plates, the striking Hverfjall volcano, and the mesmerizing Aurora Borealis, enhancing the overall experience of the space.

Material Use

Charcoal wood cladding is used for both the tower and the welcome center. This choice of material creates a visual connection with the surrounding volcanic rock. The dark wood contrasts with the bright winter landscape, helping the structures blend into their surroundings, while still standing out as architectural features.

Spatial Integration

The design divides the structure into two main parts: one dedicated to the observation tower and the other serving additional program needs. This arrangement allows for a thoughtful connection between the two tectonic plates. Lookout points are positioned to provide wide views, focusing attention on the remarkable geological features that surround the site. Each window frames a view, inviting visitors to engage with the stunning Icelandic landscape.

`
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.
