Carved voids within porous volcanic rock create a unique thermal space that seamlessly blends with the black lava fields, offering an engaging visitor center experience.
5 key facts about this project
01
Carved voids within the building enhance natural light penetration and ventilation.
02
The design adapts to the volcanic terrain, integrating with the black lava landscape.
03
Positive and negative volumes create a dynamic spatial experience for visitors.
04
Areas are arranged to encourage exploration and engagement with the environment.
05
The center emphasizes geothermal energy awareness through its architectural form.

The visitor center located in the black lava fields of Iceland serves as both a functional and informational space within a unique geological context. This design focuses on creating a connection with the surrounding volcanic landscape. By exploring the concept of 'thermal' space, the center integrates both positive and negative volumes, mirroring the characteristics of the environment.

Conceptual Framework

The design is based on the remarkable features of the local geology, including lava flows and porous rock formations. Through techniques of carving and subtracting from volcanic materials, the project crafts an environment that resonates with natural forces. This method highlights the relationship between the structure and its surroundings, fostering an understanding of the site's geothermal energy.

Spatial Organization

A range of functional areas is incorporated into the visitor center, including an entrance, lobby, gallery/exhibition spaces, kitchen, café, terrace/playground, office, restroom facilities, and staff areas. Each space is carefully arranged to promote smooth movement and interaction. The design effectively guides visitors through the center, encouraging engagement with both the architecture and the natural environment.

Environmental Considerations

The design process took into account several climate factors such as wind direction and seasonal variations in sunlight. These elements played a crucial role in shaping the organization of spaces within the center, allowing for the optimization of natural light and ventilation. The thoughtful arrangement of areas enhances visitor comfort and creates a more inviting atmosphere.

Visual representations clarify the design's intent. The ground plan clearly illustrates how different program areas relate to one another. Exploded axonometric drawings define spatial connections and volumes, while sections reveal interactions between various levels, enriching the journey throughout the center. Design iterations emphasize the importance of creating spaces that harmonize with the volcanic landscape.

As individuals approach the center, they encounter an entry sequence that reflects the surrounding topography. The contours of the building echo the undulating forms of the lava fields, creating an integrated experience between structure and landscape.

`
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.
