The design at Grjótagjá is focused on addressing the challenges brought on by rising tourism in Iceland. Located in a landscape known for its natural beauty, the project includes a viewing tower and visitor facilities. The aim is to create infrastructure that not only enhances the experience for tourists but also supports the preservation of the unique environment. By emphasizing a sustainable approach, the design encourages respectful interactions between visitors and the surrounding geology.

Design Concept

At the heart of the design is a viewing tower that maximizes the scenic vistas of the area. The tower is elevated on stilts, which helps reduce its impact on the ground below. This feature also removes the necessity for winter snow maintenance, allowing for views that are unobstructed. The structure's height provides visitors with a broad perspective of the picturesque landscape, fostering a deeper appreciation for the site.

Spatial Arrangement

The project's layout includes various seating areas that promote engagement among visitors. A rooftop amphitheater acts as a space for outdoor learning and storytelling, enhancing the educational experience. The design makes use of different levels and angled edges, adding visual interest and encouraging visitors to observe the details of the landscape more closely.

Pathways and Materials

Walkways throughout the design are carefully planned to ensure safe access while guiding visitors through the site. These paths use simple materials to promote a cohesive look across the area and facilitate ease of movement. The proposal suggests using charred larch boards for cladding, inspired by the local volcano Hverfjall. This connection to the regional geography adds an element of authenticity and improves the structure's resilience against Iceland's climate.

Sustainability Initiatives

The design incorporates principles of energy efficiency by following Passivhaus standards. This approach minimizes heat loss and maximizes comfort within the building. The project also plans to utilize geothermal energy, highlighting its commitment to sustainable practices. Operating off-grid, it supports essential visitor services while reinforcing the importance of ecological care.

The tower features carefully designed edges that enhance visual access and create patterns of shadow throughout the day, adjusting with the sun's movement. The result is a structure that engages with both its environment and its visitors, offering a thoughtful approach to the interaction between landscape and architecture.

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.
