Subscribers only
Constructed with lava rocks and enclosed in polycarbonate, the restaurant in the Myvatn region offers a unique dining experience that integrates sustainable practices with a strong connection to the surrounding landscape.
5 key facts about this project
01
Lava rocks serve as thermal mass to regulate temperature and humidity.
02
The greenhouse features a double-walled polycarbonate envelope for optimal light diffusion.
03
An "invisible staircase" connects elevated platforms to the surrounding garden.
04
Vegetables are grown on-site to provide fresh ingredients for the restaurant.
05
The exterior is clad in durable black corrugated iron, suited for local weather conditions.

The restaurant in the Myvatn region of Iceland aims to create a strong link between its visitors and the beautiful surrounding landscape. With a focus on biophilic design, the aim is to provide a dining experience that connects indoor and outdoor spaces, allowing guests to appreciate the natural environment.

Functional Areas

The design consists of various distinct areas that cater to different activities. There are spaces for education, a section for growing vegetables, and an exhibition hall for workshops. The layout is designed to enhance visitor engagement. A key feature is the "invisible staircase," which lifts visitors above the greenery and offers views of the breathtaking landscape, encouraging them to interact with the natural surroundings.

Landscape Integration

The garden is divided into three sections: a botanical garden at the lower level, a social area in the middle, and a farming zone for growing organic food. This layout serves both aesthetic and practical functions. The farming area contributes fresh ingredients to the restaurant’s menu, ensuring that meals are locally sourced. These distinct spaces foster community interaction and offer visitors a way to connect with nature.

Material Use

The project incorporates materials that fit both its environment and its design goals. The exterior uses black corrugated iron, a strong material commonly found in Icelandic buildings, providing resistance to rain and salt. The facades of the greenhouse use a double-walled polycarbonate structure, which maximizes natural light and creates visual links between the inside and outside, enhancing the dining experience.

Climatic Responsiveness

The design takes climate into account through the use of geothermal heating and thermal mass systems. Under-floor heating ensures the comfort of guests, while lava rocks serve as a thermal mass, helping to regulate temperature and humidity levels. This attention to environmental factors highlights a commitment to sustainability and improves the restaurant's overall function.

The thoughtful arrangement of functional areas combined with natural elements allows the dining experience to be deeply connected to the stunning Myvatn landscape, creating an environment where architecture and nature coexist.

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.
