Inspired by volcanic forms, the building seamlessly integrates local basalt stone into its landscape, offering a vibrant community space for exhibitions and nature activities.
5 key facts about this project
01
Inspired by geological forms, the building mimics the shape of a volcano.
02
Local basalt stone is used extensively for the exterior, enhancing environmental integration.
03
An underground link enhances sensory experiences and connects different spaces.
04
The interior features a circular layout to promote organic movement and interaction.
05
Designed as a hub, it accommodates a variety of community-focused activities and events.

The design presents a unique interpretation of volcanic forms, redefining what a building can be. Located in a landscape marked by natural features, the concept turns the structure into a spatial experience that resonates with the notion of a volcano. Through distinct sequences—The Outside, The Inbetween, and The Inside—the design encourages a connection between the built environment and its natural surroundings, emphasizing both purpose and visual appeal.

The Outside

The journey begins at the exterior, where the building evokes the raw qualities of a volcano. Its shape mirrors the natural landscape, offering an organic profile that feels familiar. Covered in local-hewn basalt stones, the outer layer enhances the visual and tactile connection to the environment. This material not only highlights the geological character of the design but also allows the structure to blend into the topography, capturing the nuances of volcanic rock.

The Inbetween

After experiencing the Outside, visitors move into the Inbetween, which serves as a connector between spaces. This underground pathway takes full advantage of the existing land, creating a natural link between what is outside and what is inside. The design encourages exploration by engaging the senses, providing a physical experience that alters the perception of time. It offers a necessary transit route while also enhancing the overall visitor experience by inviting curiosity and discovery.

The Inside

Entering the heart of the building reveals the Inside, a vibrant space intended for a range of activities. It is organized in a circular format, promoting fluid movement and interaction among visitors. Ample natural light floods this area, creating an inviting atmosphere that changes with the seasons. Designed to accommodate various uses—from exhibitions to community gatherings—the Inside becomes a central hub for engagement and creativity.

The careful integration of space and light supports the narrative of this design, reflecting the relationship between the architecture and its natural context. Each element has been thoughtfully arranged to serve practical functions while embodying the spirit of the geological phenomena it aims to represent. The balance of elements within the Inside enriches the experience, encouraging visitors to connect with the architectural landscape in meaningful ways.

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.
