5 key facts about this project
01
Cave-like interior enhances the dining experience by creating a unique atmospheric setting.
02
Local rocks are used for the main structure, promoting sustainability and ecological harmony.
03

05
The layout preserves original topography, creating distinct dining and greenhouse spaces.

The Rock Greenhouse Restaurant is located in Iceland and reflects a strong connection to the natural environment around it. The design focuses on reducing human impact while emphasizing the beauty of the landscape. It serves as both a dining area and a greenhouse, enriching the experience for visitors by bringing them closer to the unique features of Hverfjall and Mývatn.

Design Integration

The structure takes cues from the landscape, bending to the existing topography rather than imposing itself upon it. The building's form follows the contours of the land, allowing it to blend in naturally. Guests can walk up onto the roof, where they can appreciate the expansive views of the surrounding scenery, which enhances the sense of being connected to the landscape.

Structural Considerations

Local materials play an important role in the construction. The main feature is a sail arch made from rocks found in the area, arranged in continuous curves that offer stability to the roof. This choice reflects the aim to use resources that are readily available while also minimizing energy used for transportation. Using local materials helps support the area's economy and retains a lower carbon footprint.

Spatial Layout

The layout inside the restaurant focuses on maintaining the terrain's original features. Different elevations create various dining and greenhouse areas, offering distinct experiences to guests. Pathways are carefully designed to follow these height changes, encouraging exploration. The interior aims for a cave-like atmosphere, inviting visitors to feel at ease in a natural setting.

Sustainability Focus

Sustainability is a key theme in the overall design. Biodegradable materials, particularly the local rocks, ensure that the building can return to nature at the end of its life cycle. Parts of the roof function as skylights, allowing sunlight in and supporting the growth of plants in the greenhouse. This dual purpose intertwines food cultivation with the dining experience, promoting a sustainable approach to design.


The Rock Greenhouse Restaurant exemplifies a thoughtful response to its site. Its design incorporates local forms and materials, honoring the Icelandic landscape while creating a functional space that serves both dining and ecological purposes.

`
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.
