5 key facts about this project
01
The restaurant incorporates hydroponic farming techniques for year-round crop production.
02
Geothermal energy from nearby hot springs is used for heating, enhancing sustainability.
03
Large glazing areas provide panoramic views of Hverfjall volcano and Myvatn Lake.
04
An open kitchen design allows diners to observe food preparation directly.
05
Zinc cladding offers durability while blending the structure with its natural surroundings.

The Iceland Greenhouse Restaurant is located in the scenic Myvatn region of North Iceland. The design brings together a dining experience and a greenhouse, encouraging visitors to connect with the food they are eating. The overall concept focuses on blending the building with the surrounding natural environment, promoting an appreciation for local plants and sustainable farming methods.

Spatial Configuration

The restaurant features large windows on its north, west, and south sides. These windows allow for wide views of the landscape, including the Hverfjall volcano and Myvatn Lake. Natural light fills the dining area, enhancing the overall atmosphere and drawing guests into the beauty of the Icelandic scenery. This connection to the outdoors is intended to enrich the dining experience.

An open kitchen is a key aspect of the design, allowing guests to see their meals being prepared. This transparency highlights the importance of fresh ingredients and encourages interaction between the kitchen staff and diners. Positioned between the greenhouse and dining spaces, the kitchen offers direct access to seasonal produce, reinforcing the link between the food and the landscape.

Sustainable Practices

Sustainability is central to the restaurant's operations. Geothermal energy from nearby hot springs is used for underfloor heating. This approach reduces energy needs while ensuring comfort for guests throughout the year. The greenhouse employs hydroponic growing methods, which enable the year-round cultivation of various vegetables and herbs. This solution addresses the challenges posed by Iceland’s cold climate, providing fresh ingredients despite seasonal limitations.

Community Engagement

The multipurpose hall is designed to accommodate a range of community events, such as weddings and gatherings. Its additional entrance improves accessibility and ensures that it is welcoming for all. The hall offers views of the Myvatn nature baths and Hverfjall volcano, reinforcing the connection to the region’s natural beauty and promoting community involvement.

The building features zinc cladding and reflective glazing, providing a durable exterior that complements its surroundings. These materials help to manage energy use while allowing for an aesthetically pleasing design that fits comfortably within the landscape. The result is a functional space that encourages visitors to engage with both the food and the environment around them.

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.
