Constructed from rammed concrete and corten steel, the design harmonizes with the Icelandic landscape while providing essential accommodation and visitor facilities for exploring the unique geological formations of the Mývatn plateau.
5 key facts about this project
01
Constructed using locally sourced rammed concrete mixed with volcanic aggregate.
02
Corten steel cladding on guest huts enhances durability and ecological integration.
03
Visitor pathways are designed to minimize impact on fragile lava fields.
04
Observation tower provides a unique vantage point over tectonic features.
05
Off-grid systems promote sustainability through rainwater collection and wind energy.

The Grjótagjá project is located in the Mývatn plateau in Iceland, an area known for its striking geological features and rich natural landscape. The design is focused on enhancing the experience of visitors while also preserving the delicate ecology of this unique environment. Inspired by natural forces such as tectonics and volcanic activity, the architecture seeks to establish a connection between human-made structures and the surrounding land.

Visitor Center

The Visitor Center is located near the entrance to the Karlagjá cave. It is designed with earth-sheltering techniques that allow it to blend into the topography. This space acts as a starting point for visitors, offering important information and a space to pause before exploring. Constructed from rammed concrete mixed with local volcanic aggregate, the center is both durable and fitting for its location.

Guest Huts

A set of guest huts provides simple accommodation for up to four people each, carefully placed above the Grjótagjá Rift. These off-grid huts focus on sustainability and comfort, ensuring guests can enjoy the views of the surrounding landscape. The design is straightforward, encouraging a close interaction with nature and promoting the concept of self-sufficient living.

Observation Tower

The observation tower stands at 12 meters tall, rising from the plateau and creating a notable feature within the landscape. This angular structure offers visitors a raised view of the rift below. It serves not only as a lookout point but also as an educational space, helping guests understand the geological processes that shaped the area. The tower provides a unique way to experience the land from a different height.

Pathways and Access

A network of pathways is included in the design to improve visitor movement across the site while protecting sensitive areas. A new parking area directs visitors to the Visitor Center, where clear paths lead to varied experiences, such as the secluded bathing spot at Kvennagjá, which is surrounded by birch trees. Each pathway is carefully planned to reduce the impact on fragile lava fields, encouraging a respectful relationship between people and the landscape.

The meticulous arrangement of features in the Grjótagjá project highlights the distinctive geological qualities of the area, offering an enriching experience for all visitors as they explore this remarkable landscape.

`
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.
