Subscribers only
Constructed with a dark tuff roof that echoes the tectonic movements of the Hverfjall volcano, the café integrates seamlessly into its dramatic landscape while providing a communal space for visitors and locals alike.
5 key facts about this project
01
Dark tuff roof mimics the surrounding volcanic landscape.
02
The building mass appears to be separated along a tectonic axis.
03
Vertical shifting of roof plates enhances spatial dynamics.
04
Glass blocks optimize natural light throughout the interior.
05
An overhanging slab connects indoor and outdoor spaces seamlessly.

The coffee shop at the Hverfjall volcano is designed to fit into the unique geological landscape defined by its dark tuff surface. It serves as both a gathering space for the community and a destination for visitors interested in the natural environment. The design aims to highlight the relationship between the building and its surroundings, using the concepts of geological movement to create an engaging and visually interesting structure.

Concept and Massing

The design illustrates a sense of movement, as if the building’s mass is being “ripped apart” along a north-south axis. This visual interpretation reflects the tectonic processes of the area, connecting the architecture to the natural forces that shaped the landscape. By creating variations in mass, the building evokes a narrative of displacement and geological activity, inviting curiosity from those who approach it.

Spatial Organization

Inside, the layout begins with a welcoming lobby that leads into an exhibition hall. This gradual opening of space allows visitors to experience a sense of flow as they navigate through the building. The design culminates in a café that is meant for socializing, encouraging visitors to gather and interact. The clear arrangement of spaces makes it easy to move around while keeping a strong link to the outside environment.

Material Integration

The roof of the coffee shop is constructed from dark tuff, which helps it blend into the surrounding volcanic terrain. This material choice strengthens the connection between the built environment and the natural landscape, as the roof’s contours are aligned with the site’s topography. The integration of this material enhances the visual and physical presence of the building within its setting.

Natural Light and Atmosphere

The design features vertical shifts in the roof plates, introducing dynamic spatial qualities. Glass blocks are strategically located to allow natural light to filter into the interior. This light adds a warm and inviting feel to the space, creating an atmosphere that connects visitors with the changing outdoor environment. The careful placement of these elements enriches the sensory experience as one moves through the building.

The design is completed with an overhanging slab that connects the interior to an outdoor terrace. This space invites visitors to step outside, reinforcing the establishment’s ties to its dramatic volcanic surroundings. The overall form and function reflect a thoughtful approach to architecture in harmony with nature.

`
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.
