Charred timber cladding and geothermal energy combine seamlessly to enhance the visitor experience and promote sustainability in a greenhouse restaurant adjacent to the scenic Hverfjall volcano.
5 key facts about this project
01
Charred timber cladding enhances durability and insulates the building effectively.
02
The design captures rainwater for irrigation, promoting sustainable water use.
03
Geothermal energy provides a self-sufficient heating solution for the greenhouse.
04
Angular roof design optimizes natural light while framing views of Hverfjall volcano.
05
Flexible interior layout supports various functions, including dining and wellness activities.

The Mývatn Greenhouse is located in a striking landscape characterized by the Hverfjall volcano and the nearby Mývatn Nature Baths. It serves both as a greenhouse and a dining area, fostering a relationship between food production and visitor experiences. The design concept is based on a careful analysis of traditional greenhouse forms, reimagined to fit within the unique ecological context of the site.

Design Concept

The design focuses on essential features of conventional greenhouses, including the ability of materials to allow light in, appropriate height for ventilation, and modularity to accommodate future growth. This departure from standard greenhouse designs results in a modern form that respects the surrounding environment. Views of the volcano are incorporated intentionally, creating a connection between the building and its natural setting.

Spatial Organization

The layout of the greenhouse is organized to encourage smooth movement between different areas. A linear flow allows visitors to navigate easily from the dining area to the greenhouse. This setup highlights the farm-to-table philosophy, where diners can see and understand the processes behind their meals. The careful placement of spaces fosters interaction, making it easy for guests to engage with both the food and the landscape.

Material Selection

Material choices are significant in shaping the greenhouse’s character. Timber is the primary choice for structural components and interior finishes, promoting a warm and inviting atmosphere. Charred timber cladding not only enhances durability but also provides an appealing visual aspect to the exterior. Additionally, rock wool or similar insulation supports energy efficiency, contributing to a practical and sustainable design.

Sustainability Strategies

Sustainability is a critical consideration, with the greenhouse relying on geothermal energy from a nearby source for its operations. The design includes mechanisms for capturing rainwater, which can be used for irrigation within the greenhouse. These strategies support a commitment to environmental responsibility and ensure the structure operates effectively within its natural surroundings.

The angled roof of the greenhouse frames the landscape while allowing natural light to flood the interior spaces. This design feature creates a shifting dance of light and shadow throughout the day, inviting visitors to enjoy an experience that connects them to both the building and the landscape around it.

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.
