Lava walls and concrete viewing platforms define a new facility in Mývatnssveit, designed to enhance visitor interaction with the region's unique geological features while providing essential services.
5 key facts about this project
01
Lava walls are integrated to blend with the local geology.
02
Concrete viewing platforms provide safe access to geological features.
03
Visitor courtyards enhance supervision and manage foot traffic.
04
The design emphasizes revegetated moorland as an ecological buffer.
05
Strategic motor access minimizes environmental impact on the gorge.

The design proposal for facilities at Grjótagjá and Vogagjá addresses the increasing number of tourists in Mývatnssveit. It combines essential services with a focus on preserving the natural landscape. The concept prioritizes connections within the environment, avoiding large or imposing structures. This approach respects the geographical importance of Grjótagjá's fault and leads visitors through a series of zones designed to enhance their experience of the area.

Site Integration

The project is structured into five key zones: arrival, general services, transition area, cave access, and camping/viewing areas. A new motor access point is located west of Grjótagjárvegur to limit its impact on the surrounding environment and protect the gorge. As visitors arrive, they encounter the General Service Area, which includes four modules. These modules offer essential facilities such as toilets, a café, and information desks. They are designed to fit naturally into the landscape, minimizing disturbances.

Ecological Transition

After leaving the General Service Area, visitors will walk through a newly vegetated moorland. This area serves as both an ecological transition space and as a pathway to the cave access points. It encourages the growth of local plants while directing foot traffic in a way that respects the site’s ecology. The pathway helps visitors appreciate the natural environment while guiding them toward the caves.

Cave Access and Viewing Platforms

Kvennagjá and Karlagjá are the two designated cave access zones. Each zone features enclosed courtyards that ensure visitor safety and effective management. This design allows for exploration of the caves while maintaining a controlled environment. The Camping and Viewing Area includes concrete stair bridges that cross the fault, providing safe vantage points for viewing Grjótagjá’s geological features. These features enhance accessibility and encourage thoughtful interaction with the landscape.

Materials and Detailing

Lava walls are used throughout the site for demarcation and control. This choice of material serves practical functions while resonating with the local geography. The lava walls blend into the surroundings, reinforcing the area’s identity and offering visitors a clearer connection to the natural environment. Such details help create a sense of place and emphasize the importance of the landscape.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
