Bifröst is an architectural design located in Iceland, combining a greenhouse and restaurant near the Mývatn thermal baths and Hverfjall volcano. The design reflects a close relationship with the surrounding landscape. It adapts to the site’s contours, presenting an organic form that complements the natural environment. This approach emphasizes not only aesthetic qualities but also sustainable practices in its overall function.

Integration with Landscape

The structure features a roof that rises from the ground to the south and incorporates a bridge, which provides partial access from the west side of the site. This design enhances the connection with the local topography. It encourages movement between indoor and outdoor spaces while maintaining a fluid architectural style throughout.

Sustainable Systems

A central river divides the catering area and the greenhouse, playing a crucial role in the building's aquaponic system. The river supports fish whose waste acts as nutrients for the plants, promoting a self-sustaining cycle. Inspired by terraced farming techniques seen in regions like China, the greenhouse emphasizes ecological responsibility and resource efficiency.

Vertical Connectivity

Access is provided by both an elevator and an exposed staircase, allowing easy movement through the building’s levels. The basement serves essential operational needs, including a staff warehouse and a geothermal power plant. This setup supports the greenhouse and restaurant, reinforcing the project’s commitment to sustainability while integrating essential functions into the design.

Lighting and Materiality

Interior spaces utilize suspended LED fixtures, creating various light dynamics that add depth and character. The material selection includes marble slabs for flooring and concrete for structural elements, ensuring durability and enhancing the visual appeal. Rigid insulation and waterproofing membranes protect against local climate conditions, while aluminum panels and trims contribute to a modern exterior finish.

The greenhouse's design features a large aquarium as a wall, further enhancing the indoor environment with natural elements. The arrangement of spaces is thoughtful, supporting both functionality and an engaging user experience.

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.
