Constructed from local basalt, the design integrates seamlessly with the Icelandic landscape while serving as a multifunctional space that includes offices, public areas, and a gallery.
5 key facts about this project
01
Local basalt is used as the primary material, reflecting the surrounding volcanic landscape.
02
The design avoids basement levels to minimize environmental disruption.
03
Office spaces are oriented towards the village of Reykjahlid, enhancing community connection.
04
Parking areas are strategically placed to preserve natural ground surfaces.
05
The building's orientation is aligned with the north-south axis, optimizing views of the Hverfjall volcano.

The project "Icelandic Cairn" is located in a strikingly beautiful landscape of Iceland and embodies a simple yet thoughtful design. It accommodates various functions, including offices, public spaces, and a gallery, all organized within a clear geometric form. The design philosophy focuses on low impact and integration with the surrounding environment, creating a connection between the structure and its setting.

Design Concept

The overall shape is a rectangular volume that measures 20 metres in width, 70 metres in length, and 7.5 metres in height. It sits directly on the natural ground, which helps it blend into the landscape. The layout separates office spaces from public areas. Offices face the village of Reykjahlid, while the gallery looks over Hverfjall volcano. This arrangement enhances how people experience the site, allowing for a meaningful interaction between the building and its environment.

Materiality

Materials are chosen with care to reflect the local context and minimize environmental impact. Basalt stone, a natural feature of the region’s volcanic landscape, serves as the main building material. Aluminum is used for structural elements and joinery. These choices create a strong connection to the site and ensure that the structure feels like a part of its surroundings.

Environmental Considerations

To reduce the environmental footprint, the design avoids traditional basement levels. Instead, all functions are arranged on a single horizontal plane for public areas, while office spaces are stacked above. Parking areas are positioned thoughtfully within the site’s topography, limiting earthworks and keeping the natural landscape intact.

The orientation of the building runs north to south, minimizing visual interruptions in the surrounding area. This approach preserves views for both the new structure and nearby buildings. As a result, the design fosters a dialogue between the architecture and nature, highlighting both in a way that enhances the experience for users.

`
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.
