A circular dome constructed with local wooden elements harnesses natural light and complements the stunning landscape of Mývatn, providing a unique environment for sustainable dining.
5 key facts about this project
01
The circular dome design optimizes natural light for sustainable agriculture.
02
Local wooden elements enhance the connection to the Icelandic landscape.
03
Two distinct greenhouse spaces support diverse dining experiences.
04

05
The project references nearby landmarks, integrating local culture into the architecture.

The HYLKI greenhouse restaurant is located in Mývatn, Iceland, and serves as both a dining space and a growing environment for food. Its design is inspired by the nearby Lake Mývatn, Hverfjall volcano, and the Mývatn Natural Baths, tying the restaurant closely to its beautiful surroundings. The building combines elements of sustainability and local culture, creating a unique experience for those who visit.

Architectural Form

The design features a circular shape that takes the form of a dome. This dome is functional and attractive, allowing for ample natural light, which is important in a region where fresh produce is hard to come by due to cold weather. The dome faces south, ensuring that the largest greenhouse space benefits from direct sunlight, which helps plants grow throughout the year.

Spatial Arrangement

The HYLKI layout includes two greenhouses. The larger dome contains the main greenhouse, while a smaller, more compact greenhouse is positioned between a multifunctional area and the main structure. This design enables smooth movement throughout the restaurant. The kitchen is located to the west, allowing for easy service to a series of small dining units where customers order their meals, enhancing the overall experience of eating at the restaurant.

Material and Aesthetic Approach

While specific materials are not discussed in detail, the design reflects the warmth and character of a typical Icelandic town. Wooden elements bring color and texture that contrast with the starkness of the surrounding landscape. This choice fosters a welcoming environment, inviting visitors to enjoy their meals while appreciating the natural beauty outside.

The central dining space encourages guests to walk through and explore both the restaurant and its connection to the outdoors. Large windows frame picturesque views of the Icelandic scenery, emphasizing the relationship between the indoor dining experience and the stunning landscape that defines the area.

`
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.
