Constructed with volcanic tuff and geopolymers, the building seamlessly integrates with its landscape, offering a pathway that enhances visitor interaction and understanding of the natural environment while serving as a functional museum.
5 key facts about this project
01
The building's roof angle mimics the slope of the Hverfjall volcano, promoting visual harmony.
02
The use of geopolymers minimizes environmental impact through reduced energy absorption and CO2 emissions.
03
A large glass facade in the coffee shop frames views of the volcano, enhancing the visitor experience.
04
The Path incorporates local geological elements, deepening the connection to the surrounding landscape.
05
Changing rooms and lockers are integrated, allowing visitors to prepare for their outdoor adventures.

The design near Hverfjall volcano focuses on creating a strong connection between visitors and the surrounding landscape. The project is built as a journey, with The Path acting as the main feature that links outdoor trails to the spaces within. This approach enhances visitor interaction with the environment and highlights the geographical importance of the Hverfjall volcano, framing each experience within the beauty of nature.

The Path
-
The Path encourages exploration and thoughtfulness. It invites users to extend their outdoor trekking experiences inside the building. This design promotes a direct relationship with the landscape, fostering a sense of discovery. The building's orientation towards both the volcano and natural light not only maximizes views but also makes efficient use of available energy.

Functional Spaces
-
The structure includes various functional spaces designed for visitor comfort. Changing rooms, lockers, and outdoor shelters address practical needs, making the experience more enjoyable. The coffee shop stands out with its large glass facade, offering panoramic views of the volcano. This design feature not only enhances the user experience but also connects the indoor space with the impressive natural landscape outside.

Materiality
-
The choice of materials is essential to the project's design. Geopolymers, specifically volcanic tuff, are used for their environmental benefits. They require less energy to produce and emit less CO2. In addition, perovskite photovoltaic cells are integrated into the building, providing energy-efficient solutions without compromising the overall aesthetic.

Exhibition Integration
-
The museum floor extends The Path, incorporating various types of ground and Icelandic rocks that connect with the exhibition's themes. This integration strengthens the relationship between the built environment and its natural context. By emphasizing local geology, the design encourages users to engage with the cultural significance of the area, adding depth to the visitor experience.

The roof is angled to follow the slope of the volcano, allowing the building to blend into its surroundings. This detail not only enhances the visual connection with the landscape but also contributes to the building’s thermal performance. It roots the design firmly in its unique geographic setting while serving practical functions.

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.
