5 key facts about this project
01
Rainwater harvesting system integrated into the roof design for sustainable water management.
02
Multiple seasonal uses for the roof, serving as both a trail and a sledding surface.
03
Large glazing panels in public areas enhance natural light and landscape views.

Elevated platforms offer unobstructed vistas of the surrounding natural features.
05
Constructed with a space frame system for improved structural efficiency and flexibility.

The design located near Lake Myvatn serves as a visitor center that encourages people to connect with the beautiful natural surroundings. The building offers opportunities to engage with significant landmarks such as Myvatn Hverfjall and nearby nature baths. The concept focuses on interaction, featuring a viewing platform that combines educational aspects with leisure activities, enriching the overall visitor experience.

Design Concept and Functionality

The roof of the building highlights versatility and seasonal use. In the summer months, it acts as a pathway that leads to the observation deck, inviting guests to explore the landscape. When winter arrives, the roof becomes a place for sledding, offering fun for both visitors and locals. The sloped design of the roof is practical as it captures rainwater, facilitating efficient drainage into systems that meet the building’s water needs.

Architectural Envelope

The building's envelope features large glass panels in areas where visitors gather, like the reception area and gallery. These openings create a sense of openness and allow natural light to fill the spaces. In contrast, the office areas make use of well-insulated walls, built with space frames and rock-wool insulation, topped with aluminum panel cladding. This careful choice of materials enhances energy efficiency and helps maintain a comfortable indoor environment, regardless of external weather conditions.

Spatial Organization

Starting with a square footprint, the design accommodates necessary functions while allowing for parking and green spaces. A courtyard is included within the design to provide a sheltered area for relaxation and social interaction. Elevated platforms throughout the structure offer striking views and enhance the connection to the landscape, allowing visitors to experience the site from different perspectives.

Key Features and Aesthetic Considerations

Noteworthy elements such as a cantilevered entrance and a dedicated observation platform enhance the building's overall character. A reflective courtyard offers a quiet space for contemplation and connects the natural and constructed environments. The design employs a minimalistic approach with few openings, creating a cohesive appearance while respecting the geographical context.

Visitors can delight in the engaging roof design, which invites exploration while offering a way to observe the remarkable landscape surrounding Lake Myvatn.

`
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.
