The project draws inspiration from traditional Icelandic Turf Houses, representing important elements of the country’s heritage while prioritizing sustainability. Located in a picturesque landscape, the design functions as a multipurpose facility that includes a restaurant, coffee shop, greenhouse, and terrace. Its overall concept blends modern architectural practices with historical references, creating a functional and inviting space for visitors.

Design Integration

The layout focuses on a central multipurpose hall that encourages movement and interaction among different areas. Each space is organized to allow easy access while enhancing the visitor experience. Large windows and openings frame views of the surrounding environment, letting guests enjoy the scenery of Hverfjall volcano and Myvatn Nature Baths.

Sustainability Features

At the heart of the design is the greenhouse, which features a south-facing facade to maximize sunlight for growing local vegetables and herbs. This thoughtful inclusion highlights a commitment to ecological responsibility and strengthens connections to local food sources. The design ensures that natural light is present throughout the building, creating a welcoming and bright atmosphere.

Structural Composition

A load-bearing timber modular system provides the foundation for the structure, allowing for an adaptable and flexible interior layout. Concrete pillars offer stability while being covered in wood cladding, which contributes to a consistent look. This combination supports openness and functionality, catering to a variety of uses without compromising the building’s integrity.

Landscape and Biophilic Design

The green turf roof serves as an important feature, providing insulation while helping the building blend with its environment. This aspect not only improves energy efficiency but also promotes biodiversity by offering a habitat for local wildlife. Thoughtful landscaping reinforces the connection between the building and its natural surroundings, adding to the overall design narrative.

The architecture culminates in a cohesive structure that uses natural materials to foster a connection with the landscape. The design reflects a contemporary approach to traditional forms, focusing on functionality and connection with the 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.
