5 key facts about this project

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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
