The Aurora Greenhouse Restaurant is located near Sandvatn Lake in Reykjahlid, Iceland. The design merges a dining space with a greenhouse, allowing guests to enjoy Icelandic cuisine while immersed in the scenic beauty of the Myvatn region. The approach focuses on blending the building into its natural surroundings, capturing the essence of the landscape in the architectural form.

Architectural Integration

The design showcases a structure that rises from the ground, similar to traditional Icelandic turf houses. This method connects the building with the landscape and encourages a sense of belonging for those who visit. The greenhouse is designed with a stepped layout, which enhances light exposure essential for growing plants while creating a source of fresh ingredients for the kitchen.

Accessibility and Flow

Two main entrances offer paths into the restaurant—one at street level and another that leads to a green roof. This variety in access points improves the movement throughout the space, allowing visitors to engage with the outside environment. The arrangement reflects an understanding of how people navigate, making the building easy to explore and enjoy.

Spatial Organization and Functionality

Inside, the restaurant features high ceilings and large windows that frame views of the beautiful landscape. Glass walls separate the dining area from the greenhouse, inviting diners to experience the growth of their food firsthand. A multipurpose room, adaptable for many activities, has been designed with natural light in mind, thanks to the use of skylights that brighten the space throughout the day.

Materiality and Aesthetic

The materials used include dark wood, glass, and corten steel. Each of these plays a role in supporting the building's goals. Dark wood adds a touch of warmth, while glass facilitates connections between the interior and exterior environments. Corten steel introduces a modern aspect that complements the natural setting, providing a cohesive look that fits well within the rugged Icelandic landscape.

The building’s design features patterns and textures that resemble the local topography, creating an aesthetic that connects both visually and conceptually with its surroundings.

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.
