5 key facts about this project
01
The structure features a black cylindrical form that represents a volcano's weight and density.
02
Two ramps are integrated to simulate the movement of lava, enhancing user interaction.
03
A central chimney serves as a visual focal point, encouraging upward exploration.
04
The exhibition hall is adaptable for various temporary displays and educational programs.
05
Spatial organization balances private office areas with public amenities, promoting collaboration and engagement.

The Tephra project presents an abstract interpretation of volcanic features, focusing specifically on the concept of tephra—rock fragments that are expelled during explosive eruptions. Situated in an environment that aligns with geological themes, the design consists of a black cylindrical shape that conveys a sense of weight and density, reflecting the qualities of a volcano. The structure serves both administrative and public functions, encouraging interaction and exploration while highlighting the dynamics associated with volcanic activity.

Internal Structure

The design incorporates two key ramps that act as pathways for movement and symbolize the flow of lava. These elements are carefully positioned within the layout, ensuring smooth transitions between different areas. A central chimney stands as an open duct, reinforcing the vertical nature of the interior and providing a focal point that guides attention upward. This configuration enhances the flow through the space, mirroring the unpredictable behaviors of volcanic eruptions.

Spatial Distribution

The project is organized across two primary levels. The subsoil level accommodates various administrative functions, including a reception area, private offices, open-plan coworking spaces, meeting rooms, a bathroom, a kitchen, and service areas. This layout balances the need for privacy and social interaction, addressing the diverse needs of those who use these spaces.

The ground floor features public amenities such as a café, additional kitchen facilities, a bathroom, an information center, and a gift shop. This arrangement not only invites visitor engagement but also supports educational activities related to volcanic themes, fostering a richer experience for the public.

Exhibition Space

A notable element of the design is the exhibition hall, which is strategically located adjacent to circulation routes. This positioning allows for flexibility in programming, accommodating temporary exhibitions that can adapt as needed. The spatial relationships encourage exploration, promoting a greater understanding of geological concepts and volcanic processes.

Natural Form

While specific materials are not detailed, the architectural language suggests forms that reflect the essence of geological processes. The relationship between the abstract representation of a volcano and the spatial organization creates a unified experience. Every design element, from the ramps to the central chimney, reinforces a connection to its volcanic inspiration, inviting reflection on the natural forces that shape the world around us.

`
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.
