5 key facts about this project
01
Charred wood exterior enhances durability and connects visually to the volcanic landscape.
02
The central fireplace serves as a focal point for social gatherings.
03
Modular greenhouse extensions allow for flexible growth based on demand.
04
Designed to minimize land excavation, preserving the natural topography.
05
Incorporates passive ventilation and geothermal energy for sustainability.

The Greenhouse Restaurant is located in Mývatn, Iceland, designed to blend into its natural surroundings. The project features a circular greenhouse concept with a pitched roof, which optimizes natural light and provides views of the nearby HVERFJALL volcano. This space serves as a restaurant and event venue, promoting community interaction while connecting visitors to the scenic landscape.

Design Concept

Inside, the restaurant spans 2000 m² and is oriented around a central fireplace, creating a warm gathering space. In addition, three greenhouse extensions, each about 1500 m², allow for flexibility and future growth. This modular approach makes it easy to adapt the facility based on changing needs while maintaining a unified design.

Structural Integration

The design minimizes the need for extensive land excavation and sits low in the landscape. This decision helps the building blend into the natural topography and preserves the beauty of the area. The careful placement enhances the building's relationship with the existing features of the site, making it visually compatible with the striking Icelandic terrain.

Sustainability Features

Sustainability plays an important role in the restaurant's design. Solar panels and geothermal energy are incorporated to improve energy efficiency. Additionally, passive ventilation systems help maintain a comfortable environment while being gentle on nature. These features emphasize a commitment to responsible design practices that respect the local ecosystem.

Materiality

The exterior of the building is clad in charred wood, a choice that combines durability with minimal maintenance requirements. This material connects visually to the volcanic landscape. Inside, warm oak finishes create an inviting atmosphere, contrasting with the exterior and enhancing the user experience. The thoughtful selection of materials reinforces the building's connection to its surroundings.

The Greenhouse Restaurant promotes community engagement with its inviting communal areas, particularly around the fireplace, encouraging visitors to gather and connect with each other.

`
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.
