A concrete structure that utilizes geothermal energy complements the seasonal visibility of the Aurora Borealis, offering an engaging experience for visitors year-round.
5 key facts about this project
01
A concrete design enhances durability against harsh Icelandic weather.
02
Geothermal energy systems provide sustainable heating throughout the year.
03
Open viewing areas are strategically positioned for optimal Aurora observation.
04
The core space reflects summer limitations, contrasting winter’s accessibility.
05
Visitor engagement is prioritized through varied functional spaces and amenities.

The design focused on the Aurora Borealis is located in Iceland, a place known for its unique natural beauty and dramatic weather patterns. The building is intended to enhance the experience of observing the Aurora throughout the entire year. It reflects the seasonal changes that affect visibility, allowing visitors to appreciate the phenomenon in both summer and winter. The overall design emphasizes these contrasts, creating spaces tailored to the visitor's experience of light and darkness.

Site Organization

The layout encourages interaction with the surrounding environment. An outer path symbolizes the accessibility of winter, providing uninterrupted views of the Aurora. This section is open and inviting, allowing visitors to immerse themselves fully in the winter landscape and its stunning displays.

In summer, visibility changes due to longer daylight hours. The building's core is designed to reflect these limitations. Here, visitors experience a more confined space that echoes the conditions of the summer months, highlighting the importance of the winter experience.

Functional Spaces

The East Elevation includes various functional areas, such as an Exhibit and Visitors Center, Coffee Shop, Office, Restrooms, Storage, and Outdoor Viewing Areas. This arrangement caters to visitor needs while enhancing their experience. Multiple spaces offer different vantage points for observing the Aurora, encouraging exploration and interaction.

The South Elevation clearly explains the differences in visibility throughout the year. It highlights how the design navigates seasonal challenges, creating an understanding of what visitors can expect depending on the time of year. By bridging these seasonal differences, the design reflects an awareness of the natural rhythms of light.

Materials and Construction

Durability and resilience are key elements in the design, with careful choices made for materials that withstand Iceland's harsh climate. Concrete slabs form a strong foundation, while waterproof membranes and sheathing help protect the building from the elements. Batt insulation and rigid insulation are included to enhance energy efficiency, promoting a sustainable approach.

Geothermal circulation adds responsiveness to the environment, reinforcing the connection between the building and its surroundings. This thoughtful selection of materials exhibits a commitment to both functionality and environmental consideration.

Transitions between open and enclosed spaces encourage visitors to experience the unique qualities of light and dark in Iceland. The design illustrates a careful relationship between architecture and nature, drawing attention to the beauty of the Aurora Borealis while enhancing the visitor's journey. Each element serves to highlight the interplay of seasonal change, creating a memorable environment for those who come to witness the natural spectacle.

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.
