The Stranded Firefly Restaurant and Greenhouse is situated in the unique landscape of Iceland, combining the functions of a dining space and a greenhouse. The design emphasizes a connection with the natural surroundings, creating an inviting atmosphere for visitors. The structure features a ring-shaped form that partially integrates with the slope of the land, enhancing the sense of harmony with the environment and offering wide views of the surrounding area.

Design Concept

The concept centers around a circular shape that reflects the relationship between the building and its landscape. By embedding part of the structure into the natural slope, the design promotes a visual and physical connection to the site. A central atrium allows light and air to flow through the spaces, creating a bright and open environment for those inside.

Spatial Organization

Inside, the layout consists of an open floor plan that supports various activities. The greenhouse surrounds the atrium, providing a space that connects indoor and outdoor experiences. The design includes a restaurant, a multipurpose hall, and an optional botanical garden that can extend into a greenhouse if necessary. This flexible arrangement makes it suitable for different events, appealing to a wide range of visitors.

Materials and Structure

Reinforced concrete and steel are used in the construction to ensure strength and transparency. The concrete slab is supported by steel pillars arranged radially, allowing for open views and a connection to the surroundings. The floor slab is anchored in the sloping terrain, while the roof consists of a layered construction that provides effective thermal insulation. Colored concrete mixed with red pigments adds a visual character that aligns with the colors found in the Icelandic landscape.

Design Details

The thoughtful balance between structure and nature is evident throughout the design. Large glass surfaces in the greenhouse allow plenty of sunlight to enter while framing views of the landscape outside. This design feature encourages visitors to engage with both the building and the natural setting. Light interacts with the materials, creating a dynamic experience that is both calming and stimulating. The overall effect fosters a deeper appreciation for the beauty of the Icelandic environment.

`
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.
