Yggdrasil Gróðurhús is a greenhouse restaurant located in Iceland, bringing together food, nature, and design. Named after the sacred tree in Norse mythology, the project reflects a deep connection to local culture and ecology. The restaurant focuses on creating a dining experience where visitors can see the origins of their meals, enhancing awareness of local food production and sustainability.

Architectural Form and Layout

The design carefully considers how diners interact with their environment. The layout places the dining areas in close proximity to the greenhouse, allowing guests to observe the cultivation process of the food they consume. This arrangement creates a direct link between the act of eating and the source of food, enriching the overall experience and fostering a sense of community.

Materiality and Performance

Materials chosen for Yggdrasil Gróðurhús are vital to its function and appearance. A steel cladding covers the exterior, offering a robust structure while giving a modern look. The presence of double-glazed windows helps to control temperature, ensuring comfort for diners. This design choice is particularly important in Iceland, where climate conditions can be quite harsh.

Ambient Light and Atmosphere

One notable aspect of the building is its unique diamond-like coating. This feature allows natural light to filter through, creating a gentle and welcoming atmosphere inside. Instead of harsh sunlight, the diffused light contributes to a peaceful dining experience. The interplay of light and shadow connects the indoor space with the outside world, enriching the ambiance.

Innovative Insulation Strategies

To maintain a comfortable climate throughout the year, innovative insulation methods have been employed. Polyurethane foam insulation is used to keep heat in during the cold months and cool air in during warmer seasons. The choice of insulation addresses the challenges presented by Iceland’s variable weather while enhancing energy efficiency.

Daylight streams through the diamond facade, casting soft patterns on the interior surfaces, creating a calming environment for guests. This design encourages diners to appreciate not just their meals, but also the natural world that produces 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.
