Constructed with lava rocks and enclosed in polycarbonate, the restaurant in the Myvatn region offers a unique dining experience that integrates sustainable practices with a strong connection to the surrounding landscape.
5 key facts about this project
01
Lava rocks serve as thermal mass to regulate temperature and humidity.
02
The greenhouse features a double-walled polycarbonate envelope for optimal light diffusion.
03
An "invisible staircase" connects elevated platforms to the surrounding garden.
04
Vegetables are grown on-site to provide fresh ingredients for the restaurant.
05
The exterior is clad in durable black corrugated iron, suited for local weather conditions.

The restaurant in the Myvatn region of Iceland aims to create a strong link between its visitors and the beautiful surrounding landscape. With a focus on biophilic design, the aim is to provide a dining experience that connects indoor and outdoor spaces, allowing guests to appreciate the natural environment.

Functional Areas

The design consists of various distinct areas that cater to different activities. There are spaces for education, a section for growing vegetables, and an exhibition hall for workshops. The layout is designed to enhance visitor engagement. A key feature is the "invisible staircase," which lifts visitors above the greenery and offers views of the breathtaking landscape, encouraging them to interact with the natural surroundings.

Landscape Integration

The garden is divided into three sections: a botanical garden at the lower level, a social area in the middle, and a farming zone for growing organic food. This layout serves both aesthetic and practical functions. The farming area contributes fresh ingredients to the restaurant’s menu, ensuring that meals are locally sourced. These distinct spaces foster community interaction and offer visitors a way to connect with nature.

Material Use

The project incorporates materials that fit both its environment and its design goals. The exterior uses black corrugated iron, a strong material commonly found in Icelandic buildings, providing resistance to rain and salt. The facades of the greenhouse use a double-walled polycarbonate structure, which maximizes natural light and creates visual links between the inside and outside, enhancing the dining experience.

Climatic Responsiveness

The design takes climate into account through the use of geothermal heating and thermal mass systems. Under-floor heating ensures the comfort of guests, while lava rocks serve as a thermal mass, helping to regulate temperature and humidity levels. This attention to environmental factors highlights a commitment to sustainability and improves the restaurant's overall function.

The thoughtful arrangement of functional areas combined with natural elements allows the dining experience to be deeply connected to the stunning Myvatn landscape, creating an environment where architecture and nature coexist.

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.
