Utilizing volcanic soil and fibre cement, a series of colorful ribbons emerge in a greenhouse structure that combines sustainable farming and dining, reflecting the harsh beauty of Iceland's landscape.
5 key facts about this project
01
Utilizes local volcanic soil in fibre cement panels to enhance environmental integration.
02
Features three colorful ribbons that visually connect the building with its landscape.
03
Incorporates geothermal energy, maximizing sustainability for agricultural practices.
04
Combines dining and cultivation spaces for direct interaction with food production.
05
Designed to withstand Iceland's harsh climate while promoting efficient farming.

The architectural design known as "Nunatak" is located near the Hverfjall volcano in Iceland. It occupies a distinctive desert landscape defined by dark volcanic soil and a rugged terrain. The design draws inspiration from the Inuit word for a rock that rises above a snowy surface. This concept reflects not only a connection to the natural surroundings but also serves practical purposes. Nunatak functions as both an agricultural facility and a dining space, allowing visitors to engage with the food production process in a unique setting.

Materials and Structure

The structure primarily uses glass and steel to create a modern appearance that fits well within its environment. Three ribbons, designed to mimic the colors of the local landscape, wrap around the building at various points. The façade incorporates fibre cement panels that contain volcanic soil from the area. This choice enhances the visual relationship with the surrounding land. T-shaped steel profiles connect the top and bottom of these panels, while IPE 450 beams ensure the building's strong framework.

Sustainable Agriculture

A key aspect of Nunatak is its commitment to sustainable farming through geothermal energy and hot water. The greenhouse plays a significant role in this effort, providing an area for various plants to grow in a controlled environment. This approach adapts to the challenges posed by the local climate, turning a harsh environment into a productive space for agriculture. The design aims to demonstrate that cultivation is possible even in difficult conditions, creating a place where farming thrives.

Visitor Interaction

The design fosters interaction between visitors and the agricultural processes taking place within the structure. Guests can walk through areas filled with hydroponic systems that grow a range of vegetables and herbs. This setup enhances their understanding of where food comes from and how it is produced. The layout allows for visibility into these farming activities, emphasizing transparency and engagement as patrons witness food production firsthand.

Design Details

Details in Nunatak contribute to the overall experience. Interior spaces combine agricultural functions with dining areas, enabling guests to see the fresh produce that they will later enjoy. Large glass surfaces allow natural light to enter, highlighting the greenery of the greenhouse against the backdrop of the volcanic landscape. This arrangement not only serves practical purposes but also enriches the overall atmosphere of the building.

`
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.
