The PIVOT Volcano Coffee Shop is an architectural project strategically located in the volcanic landscapes of Iceland. This coffee shop is designed not only to serve beverages but to enhance the experience of its natural surroundings. Its architecture fosters a connection between visitors and the geothermal features of the area, emphasizing sustainable practices and environmental engagement.

The structure is characterized by a circular form that adapts to the natural contours of the topography. This design choice minimizes the visual impact on the landscape while offering an immersive spatial experience. The building features extensive use of glass, allowing for panoramic views of the volcanic environment. Visitors are invited to engage with the surrounding landscape from the interior spaces, underlining a concept of openness and connection to nature.

The project serves multiple functions: it operates as a coffee shop, a gathering space for community interaction, and an educational hub that showcases the unique geological context of Iceland. The interior layout includes various zones for seating, dining, and educational displays about volcanic activity and Icelandic culture.

The integration of a green roof is a particularly unique aspect of this design, which not only aids in insulation but promotes local biodiversity. The roof serves as an extension of the natural landscape, inviting visitors to appreciate the ecological richness of the site. Additionally, the building employs sustainable materials such as post-tension concrete and fritted glass that enhance the structural integrity while ensuring energy efficiency.

Another significant aspect of the PIVOT project is its emphasis on movement—a concept represented through the design of pathways that guide visitors from entryways into the coffee shop's main areas. This design promotes a journey through the space, encouraging exploration and interaction.

Architectural plans and sections provide valuable insights into the spatial organization and materiality of the project. By reviewing these elements, one can understand the thoughtful approaches taken in this design that prioritize ecological sensitivity and user experience.

To gain a comprehensive understanding of the PIVOT Volcano Coffee Shop and its design intricacies, including architectural ideas and visual representations, explore the project presentation further. An overview of the architectural designs will enhance the appreciation of this unique architectural endeavor in Iceland.

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.
