Subscribers only
A translucent outer shell envelops a robust steel frame, creating a community center that fosters interaction and connection while minimizing environmental impact in the Kvennagjá Grottos.
5 key facts about this project
01
Community center elevated 1.5 meters to prevent snow accumulation.
02
Footprint reduced to a quarter of its original size to restore natural areas.
03
Visitors access limited to five at a time for a personal experience.
04
Translucent materials allow internal lighting to guide visitors at night.
05
Steel frame construction provides durability against extreme weather conditions.

Höggmyndagarður is located in the Kvennagjá Grottos and aims to enhance the experience of visitors while focusing on environmental care. The design emphasizes reducing the impact of car access and revitalizing the natural landscape around it. This project integrates spaces that serve both tourists and the local community, creating a relationship between nature and the structures built within it.

Community Center
The community center stands tall at 7 meters, elevated 1.5 meters to prevent issues with snow. With four structural feet, the design reduces its impact on the ground below. This space serves as both an information center for visitors and a gathering place for locals, featuring a café-restaurant that can host up to 24 people. This multifunctionality encourages community engagement and social interaction.

Access and Parking
A roundabout parking layout is designed to handle visitor traffic effectively while creating an appealing entrance to the site. It directs guests back to the main road when parking reaches capacity, ensuring smooth movement and reducing potential congestion. By cutting down on paved areas, the design helps restore the natural beauty that existed before development.

Structural Integrity
The building utilizes a strong steel frame, offering durability and stability against harsh weather conditions. Internal systems for water, electricity, and drainage are carefully placed to keep the aesthetic of the site intact. The tower is anchored securely to the bedrock and supported by steel cables, which enhances its overall stability. A translucent outer shell allows light to shine through, guiding visitors during evening hours.

Visitor Experience
The design limits access to both the tower and cave to five people at a time, providing a more personal connection with the environment. Guided pathways protect safety, encouraging thoughtful interaction with nature while demonstrating a commitment to preserving it. Through these design elements, visitors can explore and engage with their surroundings in a meaningful way.

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.
