VolcanOH is a new lookout point located near Hverfjall, an extinct tuff ring volcano in Iceland. The design aims to provide visitors with expansive views of the stunning landscape while offering a space to retreat from the changing weather. The overall concept emphasizes a strong connection to nature, blending functional elements with an aesthetic that captures the essence of volcanic activity.

Design Concept

The concept behind volcanOH focuses on connecting human experience with the environment. The structure is elevated, allowing for wide vistas of Hverfjall and the surrounding area. Three wooden platforms encircle the main structure, designed to mimic the movement of clouds. This layout encourages exploration and moments of reflection, guiding visitors to engage with the natural setting.

Spatial Organization

A central element of the design is the indoor fireplace, which enhances the atmosphere and provides warmth. Together with strategically placed skylights and mural openings, it creates a calming environment. The lookout point is organized around a base that resembles a volcano, leading visitors up several levels of platforms. This ascending pathway immerses people in the landscape before they reach the main observation area.

Materiality

Hempcrete serves as the primary building material, selected for its sustainability and fire-resistant characteristics. Much lighter than concrete, hempcrete allows for efficient construction in the challenging climate. The wooden framework lends structural support while complementing the building's overall design. The exterior cladding is chosen to blend with the dark tones of the Icelandic landscape, reinforcing the link between the architecture and its natural surroundings.

Architectural Detail

The design includes unique features, such as a hanging net, providing visitors with an immersive experience. People can lie suspended, surrounded by picturesque views. This detail invites deeper interaction with the landscape, encouraging individuals to appreciate the tranquil beauty of Hverfjall. Throughout the design, the relationship between structure and nature is central, creating a space that enhances the experience of the volcanic terrain.

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.
