The architectural design is set against a mountainous landscape in Iceland, focusing on a thoughtful integration with the surrounding environment. At its core, the concept explores an interface façade that redefines the traditional role of a façade, acting as both a divide and a connection between indoor spaces and the natural world. The primary function involves a greenhouse that supports local agriculture while also serving as a gathering space for community activities.

Design Concept

The interface façade moves beyond the typical function of a wall. It creates a connection that allows natural elements to flow into the building. The structure is designed as a single-story volume partially embedded in the ground. This choice helps minimize the visual impact and enhances the relationship with the land.

Community Engagement

At the heart of the project is the greenhouse, designed to grow vegetables for local distribution. These greens may reach various venues, such as the Diamond Circle visitor center and nearby restaurants. This effort encourages community ties and emphasizes the value of local resources. Visitors are invited to participate in picking fresh produce, which reinforces their connection to the food they eat.

Spatial Organization

Spaces are thoughtfully arranged and include areas like the restaurant, hall, and administration. This layout supports community gatherings while providing clear circulation paths for different activities. The greenhouse features a glass roof, allowing ample natural light for plant growth, while interactive zones are shaded by wooden roofs, offering comfort for those visiting.

Sustainability Measures

Sustainability plays a vital role in the design. High-temperature heat source water from a nearby thermal power plant is used to maintain optimal conditions in the greenhouse. Rainwater is collected for irrigation, ensuring an efficient water use. Carbon dioxide captured from nearby facilities contributes to the greenhouse's growth cycle.

Guests enjoy views of Hverfjall Volcano, creating a direct connection to the Icelandic landscape. The design elements thoughtfully encourage interactions between the built environment and nature, emphasizing the importance of both in everyday life.

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.
