The Ridge is situated on the Mid-Atlantic Ridge in Iceland, connecting architecture with the natural landscape. The building functions as a volcano museum and exhibition space, aimed at educating visitors about the geological features that shape the area. The design is based on the theme of divergence, reflecting the tectonic activities that define both the region and the island itself.

Architectural Form and Layout

The design creates a prominent void that diverges from two solid volumes. This void symbolizes the geological processes of the area. The southern volume hosts a coffee shop, offering views of the Hverfjall volcano, while the northern volume contains private areas like an information desk, offices, and service rooms. This thoughtful separation of spaces helps visitors navigate through the building easily.

Materiality and Connection to Place

Locally relevant materials are incorporated into the design. Interior walls are clad in basalt stone, which mirrors the geological composition of Iceland. The roof is made of dark timber, enhancing how the building fits into its surroundings. The use of timber in the structural framework is carefully coordinated, creating a visual connection with the natural lines found in the area.

Sustainability and Functionality

Sustainability is an important aspect of the design. The Ridge uses geothermal energy for heating and cooling, aligning with Iceland's environmental practices. The open space museum features roof glazing to welcome natural light, making the void feel inviting for exhibitions. The flexible design allows the museum to host different temporary exhibitions, ensuring that it remains engaging and relevant to visitors.

The layout emphasizes accessibility, with the main entrance positioned on the southern side. This allows visitors to flow directly from the road and hiking trails into the building. This design choice enhances the experience, creating a smooth transition from the outdoor landscape to the interior museum. The void serves not only as an architectural feature but also as a way to connect visitors to the geological story of the region.

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.
