5 key facts about this project
01
Geothermal heating maintains a consistent temperature year-round in the greenhouse.
02
Framed glass walls provide unobstructed views of the Hverfjall volcano.

Piles support the structure, allowing natural water flow beneath the building.
05
Movable window louvers adjust light levels to suit changing weather conditions.

The Aurora Greenhouse project is a multifunctional facility located in Iceland, combining a year-round greenhouse, a restaurant, and various activity spaces. The design focuses on sustainability and community involvement, highlighting the connections between food production and consumption while appreciating the beauty of the surrounding landscape.

Architectural Concept

At the center of the design is the greenhouse, which acts as a focal point that invites visitors into the building. This space allows people to engage directly with the cultivation of vegetables, fruits, and other greens. Visitors can participate in the growing process, creating a hands-on experience. This approach not only promotes understanding of local food sources but also fosters a sense of community among those who gather here.

Spatial Relationships

Large glass walls are placed throughout the facility to offer stunning views of the Hverfjall volcano and Mývatn Nature Baths. These openings let in natural light and create a strong connection between the inside and outside. This relationship with nature enhances the experience of users and serves as a constant reminder of the beautiful landscape that surrounds them.

Sustainability Features

A geothermal heat exchange system is utilized to maintain stable temperatures within the greenhouse year-round. This feature demonstrates a commitment to renewable energy sources. Alongside this, a heat recovery system helps recirculate warm air to improve energy efficiency. These systems highlight careful planning in responding to the needs of the environment while being mindful of energy conservation.

Structural Considerations

The building is supported by piles to effectively manage the challenging terrain of the site. This foundation method ensures stability while allowing for air and water flow beneath the structure. The first-floor ceiling is designed with wooden trusses, which provide necessary support and add a natural feel to the interior. Movable window louvers are included to regulate light, allowing the space to adapt to Iceland's ever-changing weather.

The Aurora Greenhouse exemplifies how a facility can balance functionality, sustainability, and a connection to nature, creating an enriching atmosphere for all who visit.

`
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.
