The Vegvisir Restaurant is located in a beautiful landscape marked by the strong presence of Hverfjall and Mývatn. It is designed to connect architecture with nature, using a circular shape that blends with the land. This layout not only serves food but also creates an experience that invites guests to feel part of the environment. The emphasis is on sustainability and reflecting local cultural values through design choices.

Architectural Concept

The main idea of the design is a pure circular form, which allows the restaurant to integrate smoothly into its surroundings. The central space features a green square that encourages interaction with nature. Surrounding the square, local plants like blueberries, berries, and small birches add to the landscape, promoting a sense of biodiversity and ecological awareness.

Spatial Organization

The layout of Vegvisir Restaurant focuses on movement and interaction. A circular path connects different areas, allowing guests to experience the sights and sounds of nature as they explore. An open kitchen acts as a highlight, allowing diners to see their food being prepared, enhancing their dining experience. Tables are arranged to keep visitors connected to the natural environment, allowing them to engage with their surroundings while they eat.

Sustainability and Materials

Sustainability is a key aspect of the design. Geothermal heat is used to maintain a comfortable temperature in the greenhouse, regardless of outside weather conditions. Rainwater is collected for irrigation and toilet use, showing a commitment to responsible water management. Wood is the primary material used, reinforcing the connection to nature and aligning with the overall design theme.

Symbolism and Cultural Context

The planting design in the greenhouse is inspired by the Vegvisir symbol, which represents guidance and relationship with nature. This thoughtful choice highlights the cultural significance of the project and strengthens its themes of interconnectedness. The architecture draws elements from traditional Viking buildings, creating a link to the region's historical identity.

Large glass facades allow natural light to enter and connect inside spaces with the landscape outside, making the environment feel open and inviting.

`
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.
