The design located in Iceland presents a thoughtful exploration of how geothermal energy can be integrated into a sustainable framework. Set against a backdrop of geothermal activity, the building functions as a greenhouse, café, and exhibition space that highlights Icelandic culture. The overall concept emphasizes efficient resource use and aims to create educational experiences around sustainable practices.

Sustainability Focus

Emphasis is placed on sustainability through the implementation of a rainwater harvesting system. This system irrigates the greenhouse and showcases methods of functional agriculture. Combining rainwater collection with geothermal heating creates an energy-efficient environment. This strategy reflects a commitment to environmental responsibility and resource management.

Spatial Organization

The layout of the building carefully arranges functional spaces to encourage movement and interaction. A lobby welcomes visitors, leading into a dining area and various multi-purpose rooms. Each space is positioned to enhance the experience of engaging with cultural exhibits and agricultural displays. This thoughtful organization fosters a connection between users and their natural surroundings.

Vertical Greenhouse

A key feature of the design is the vertical greenhouse, which uses a three-dimensional approach to cultivation. This innovative method maximizes available space while educating visitors about modern agricultural techniques. Visitors can navigate a vertical traffic system that includes a rotating staircase, allowing them to view agricultural processes from different angles while appreciating the natural landscape outside.

Structural Elements

The selection of materials is crucial for both performance and aesthetics. Tempered insulating glass is used to maintain thermal comfort, while an aluminium frame provides structural strength. Structural adhesives and sealants support the durability needed to endure Iceland's specific climate challenges. These choices underline the project’s focus on robust environmental design.

Expansive glazing throughout the structure invites ample natural light and creates visual connections to the dramatic scenery. Views of glaciers and volcanic formations reinforce the relationship between the building and its environment. The design cultivates a sense of belonging, inviting visitors to appreciate both the architecture and the rich Icelandic landscape.

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.
