5 key facts about this project
01
Exposed geothermal systems visibly demonstrate energy use throughout the building.
02
High-peaked roofs reflect traditional Icelandic farm architecture.
03
A central gallery serves as a dynamic social hub for community interactions.
04
Durable concrete exterior withstands harsh Icelandic weather conditions.
05
Interior wood finishes create a warm atmosphere contrasting the robust exterior.

The project is located in Iceland, a region known for its rugged landscapes and the potential of geothermal energy. It focuses on agricultural production while creating a strong connection between local producers and consumers. The design concept emphasizes the journey of fresh produce from soil to plate. By doing this, it aims to educate visitors on the agricultural process and promote an awareness of food origins. Functioning as both a workspace and a learning environment, the building integrates local agricultural practices with community involvement.

Design Approach

The design draws inspiration from traditional Icelandic architecture, particularly the farms of the 10th and 11th centuries. It consists of multiple functional elements that connect through a central gallery. This central space acts as a social hub, fostering interaction among visitors while ensuring that the different parts of the building operate cohesively as one unit.

Form and Silhouette

The form of the building features several volumes, each topped with high-peaked roofs. This results in a compact and recognizable shape that fits well within the surrounding landscape. The structure is securely anchored to the ground, minimizing its environmental footprint while asserting a strong presence in the often harsh Icelandic surroundings.

Materiality

A clear contrast exists between the building’s exterior and interior. The outside is made from raw concrete, which reflects the toughness of the landscape and provides durability against weather conditions. In contrast, the interior makes use of wood, creating a comfortable and inviting space. This combination of materials helps enhance user experience while maintaining a connection to the external environment.

Functional Versatility

The design allows for different modes of operation to serve the community effectively. During the day, visitors can explore various areas related to production and agriculture. In the evening, spaces such as the bar, restaurant, and market become accessible from the main square. Additionally, the exposed geothermal system within the building serves both functional and educational purposes. It illustrates how the building works while emphasizing sustainability.

The central gallery, filled with natural light, includes features that bring elements of nature inside. This integration fosters an environment that encourages users to appreciate the relationship between architecture and the landscape around them. Such details create a calm atmosphere for anyone who enters, inviting them to explore the connections between the interior and the outside world.

`
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.
