Set within the unique landscape of Hverfjall Volcano, a vertical greenhouse utilizes geothermal energy to create a sustainable dining experience that integrates community and agriculture.
5 key facts about this project
01
A vertical greenhouse design maximizes sunlight exposure and space efficiency.
02
Geothermal energy systems provide sustainable heating and cooling throughout the year.
03
Guests can directly participate in food cultivation by interacting with the greenhouse.
04
Transparent glass walls enhance views, merging the interior with the surrounding landscape.
05
The restaurant accommodates seasonal offerings based on harvested produce from the site.

The design is located within the unique landscape of Hverfjall Volcano in Iceland, serving as both a greenhouse and restaurant. The concept emphasizes sustainability, combining the processes of growing food with an engaging dining experience. The building is partially underground, allowing it to blend naturally with the volcanic terrain. Utilizing geothermal energy efficiently, the structure maintains comfortable temperatures while minimizing its impact on the environment.

Design Integration

A vertical greenhouse is at the center of the project, surrounded by a courtyard that invites interaction between guests and the growing environment. This design allows for around 100 guests to gather in a space that feels open and connected to nature. The use of transparent glass walls around the courtyard enhances the views of the internal plants and the surrounding landscape, creating a sense of unity between inside and outside.

Sustainability Strategies

Sustainability is a primary focus of the design, with energy strategies including solar power and harvested rainwater. The architecture uses passive heating and cooling techniques, along with an efficient system to regulate temperatures inside the building. These features ensure a comfortable atmosphere for diners while keeping energy consumption low.

Connection to Food Source

The relationship between the kitchen and the greenhouse forms a direct link between food production and dining. An open kitchen located at the bottom of the vertical greenhouse allows fresh produce to be delivered straight to the tables. This process highlights the connection between the ingredients and their preparation, inviting guests to experience their meals in a more engaged way.

Automated systems within the greenhouse manage temperature, humidity, and light to support optimal growing conditions for various plants. This careful attention to detail extends throughout the design, making it functional both as a restaurant and as a living space for growth. The commitment to merging agricultural practices with the dining experience embodies a thoughtful approach to design within a natural setting.

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.
