The Tephra Cone is an architectural project located in north Iceland near Lake Myvatn, designed as a multifunctional space that integrates a coffee shop and information center. The building is situated in a region characterized by volcanic landscapes and geothermal features, creating a unique contextual backdrop. The architectural design aligns with its environment, emphasizing a connection to the natural terrain while providing visitors with an engaging experience.

The primary function of the Tephra Cone is to serve as a gathering place for tourists and locals, offering amenities that enhance the exploration of the surrounding volcanic geography. The structure invites interaction through its design, encouraging visitors to experience both the interior and the exterior landscapes. Its layout facilitates various activities, from casual dining to exhibitions, while maintaining a focus on the overall user experience within the distinct setting.

In terms of design, the Tephra Cone employs several noteworthy approaches that differentiate it from conventional architecture. The circular form of the building echoes the geological features of the area, specifically the volcanic cones that shape the landscape. This decision creates a seamless dialogue between the structure and its environment, reinforcing the narrative of place. The use of local materials is another vital aspect of the project. The timber frame construction and incorporation of lava aggregates in the concrete foundation not only ensure structural integrity but also reflect the characteristics of the surrounding environment, contributing to a sense of place.

The spatial organization within the Tephra Cone emphasizes transparency and openness, allowing natural light to filter into the interior while providing panoramic views of the external landscape. The integration of large glass windows blurs the boundary between inside and outside, inviting the landscape into the visitor's experience. Additionally, the design features varied heights and diameters, which creates dynamic spatial experiences that encourage exploration and interaction among users.

The incorporation of a courtyard area within the design encourages outdoor engagement, providing a setting for potential exhibitions while ensuring visitors can appreciate the natural beauty of the landscape. This outdoor space enhances the accessibility of the project, encouraging foot traffic and interaction between the building and its surroundings.

Overall, the Tephra Cone stands as a well-considered architectural project that respects and engages with its landscape. Its design reflects a commitment to sustainability, functionality, and interaction, making it a significant addition to the Icelandic region. For those interested in further understanding the architectural plans, sections, and unique design ideas, exploring the project presentation will provide deeper insights.

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.
