The Grjótagjá Iceland Caves project is designed to blend with the distinct geological features of Iceland. Located among volcanic formations, it aims to create a space that is both functional and connected to nature. The overall design concept is centered on sustainability and modularity, allowing the structure to interact naturally with its environment. It establishes a framework based on four guiding ideas: locating, shaping, elevating, and connecting, all of which enhance visitors’ experiences in the landscape.

Architectural Concept

At its core, the design promotes a close relationship between people and the landscape. A modular approach allows pathways to become more than just routes; they function as bridges, stairs, and platforms for walking. This flexibility encourages movement throughout the area while inviting visitors to engage with the beauty of their surroundings. Each pathway, built as a wooden deck, rests on a strong wood structure supported by foundation piles. This method ensures adaptability to the site’s varied terrain.

Environmental Sustainability

The project emphasizes sustainability as a key element. Solar panels are placed throughout the site to collect renewable energy. Rainwater recuperators are included to provide a reliable source of drinking water. The green roofs contribute to energy efficiency by enhancing thermal insulation while also promoting wildlife. These features ensure that the project meets its energy needs and aligns with eco-friendly practices.

Structural Systems

The structures consist of a laminate wood skeleton that demonstrates a focus on sustainable construction. By using wood— a renewable resource— the design minimizes its environmental impact. The building’s outer layer features burned wood cladding, which not only provides durability but also creates an aesthetic that reflects the surrounding volcanic landscape.

Visitor Experience

Central to the design are spaces for gathering, including an observation tower and a café, placed to encourage interaction among visitors. A footbridge connects these spaces, offering glimpses of the remarkable geological features nearby. This connection allows for easy movement while enhancing the overall experience, enabling visitors to appreciate the landscape's natural details and unique characteristics.

`
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.
