5 key facts about this project
01
ETERNAL BOOK design resembles an open book, symbolizing knowledge and community connection.
02
A small lake within the site regulates humidity and enhances the microclimate for plant growth.
03
Indoor farming facilities promote local agricultural practices and community engagement.
04
The panoramic terrace offers views of Mývatn Nature Baths and Hverfjall Volcano.
05
Separate access routes improve visitor flow and operational efficiency within the building.

EIVIÐBÓK, known as the ETERNAL BOOK, is located in Iceland and captures the spirit of literature and community. The design draws inspiration from the idea of an open book, influencing both its appearance and functionality. The building serves as a gathering space that supports education and agricultural practices, fitting comfortably within its natural surroundings.

Architecture Concept

The design features a roundabout that includes a greenhouse plant nursery and a small lake. This lake adds to the visual appeal and helps regulate moisture in the air, creating a healthy environment for plants and visitors. The entrance hall is designed for easy access, with an information desk and ramps that lead to an upper terrace, allowing for smooth movement throughout different areas of the building.

Functional Spaces

EIVIÐBÓK is designed to serve multiple purposes. The second level of the greenhouse acts as a dining space, featuring 25 tables that can accommodate around 100 diners. This setup encourages communal meals and provides views into the greenhouse, reinforcing the link between food and local agriculture.

Integration of Nature

Large windows and ample glass allow natural light to fill the building, creating a strong connection between indoor and outdoor spaces. The roof terrace offers both enclosed and open areas for various activities. Users can enjoy views of the nearby Mývatn Nature Baths and Hverfjall Volcano, enhancing their experience of the landscape.

Material Utilization

The building is constructed using reinforced and prestressed concrete, along with steel, ensuring it can withstand the harsh Icelandic climate. These materials not only provide stability but also support the design's functionality. Careful planning has resulted in separate access for visitors and employees, improving the overall flow of movement in the space.

A notable feature is the integration of indoor farming capabilities, promoting sustainable practices that are relevant to the local agricultural community. This aspect underscores the intent to foster interaction among visitors while being mindful of the environment. The careful blend of space and function makes EIVIÐBÓK a thoughtful addition to its setting.

`
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.
