The Nub is designed to enhance the Icelandic film industry by providing a hub for both cinematic and educational experiences. Located in the breathtaking landscapes of Iceland, it combines a screening room with a cinema, aiming to narrate the rich history of Icelandic cinematography. The design fosters an immersive environment that encourages visitors to engage with both the films and the surrounding natural beauty.

Design Concept

The layout features two interconnected circles. The inner circle is reserved for the cinema and essential service areas, such as administrative offices and storage. The outer circle acts as a public space, encouraging visitor movement and interaction with various educational exhibits. This arrangement enhances overall visitor experience by allowing for smooth transitions between different functions.

Structural Composition

The building's circular form takes inspiration from the local geography. It mimics a cinematographer's reel, with large concrete slabs making up the main structure. Glass elements punctuate these slabs, allowing natural light to illuminate the interior spaces. This design choice not only brightens the environment but also connects visitors with the external scenery, weaving the experience of film into the broader context of the landscape.

Materiality

Materials have been thoughtfully selected to strengthen the connection with the environment. Precast concrete elements that use volcanic aggregates sourced from local rocks and ash form the outer facade. This choice creates a visual harmony with the surroundings. Additionally, peat turf walls are integrated into the design, offering effective insulation while paying homage to traditional Icelandic construction methods.

Sustainability Strategies

Sustainability is an important aspect of the design. The Nub includes features such as geothermal heating and cooling systems, a rainwater collection system, and greywater recycling through biofilters. These elements reflect a commitment to minimizing the ecological footprint of the building. They also demonstrate how modern architecture can operate in harmony with environmental considerations.

The entrance foyer provides a panoramic view of the Icelandic landscape. It serves as a focal point for visitors, inviting them to connect with both the cinematic experience and the natural surroundings. This detail enriches the overall experience, merging the world of film with the stunning beauty of Iceland.

`
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.
