Nýja Borgin, or "The New Castle," sits at the Dimmuborgir site in Iceland. It serves as a visitor center designed to blend with the unique geological features of the area. The architecture reflects the natural shapes found in the surrounding black lava fields, striving to create a sense of connection between people and the environment. The design aims to invite exploration and create meaningful interactions with the distinctive landscape.

Design Layout

The building is positioned on a small hill, providing wide views of the landscape. This location builds a relationship between the structure and the surrounding terrain. Visitors enter through a central space that leads them to different areas. On the left is the main exhibition room, while the café is conveniently located on the right. This layout makes it easy for guests to navigate and encourages engagement with the various offerings.

Functional Spaces

A notable feature of Nýja Borgin is the multimedia room, which expands the exhibition area. This space can accommodate various presentations and group meetings. The floor in this room is lowered to match the slope of the site, allowing for comfortable seating arrangements. This attention to detail supports a user-friendly experience while maintaining a cohesive design with the building.

Materiality

The project uses materials that enhance the connection to the environment. The outer layer of the building is made from gabions filled with stones sourced locally, reflecting the unique geological formations of Dimmuborgir. This choice reinforces the bond with the surrounding landscape while providing a sturdy shell for the center. Inside, the use of wooden walls and roofs brings warmth to the interior spaces, creating a contrast with the rugged exterior.

Landscape Integration

Nýja Borgin reflects a commitment to the natural setting by minimizing its impact on the landscape. Adjustments were made to the parking area, allowing it to align with the existing contours of the site. This approach reduces the overall environmental footprint. A new road connection facilitates the arrival experience for visitors, making it simple for buses and cars to drop off passengers and park within a designated area.

One of the distinct features is the rooftop terrace, which offers expansive views of the landscape. This space allows visitors to take in the beauty of Dimmuborgir from above, enriching their experience and providing a platform to appreciate the unique geological formations of the area.

`
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.
