The site near the inner volcanic crater of Hverfjall in Iceland presents an opportunity for visitors to engage closely with the natural landscape. The design focuses on access and interaction, featuring a movable staircase and a building structure that can rotate. These features encourage exploration, allowing individuals to experience the unique geological formations from different perspectives.

Movable Staircase
A key element of the design is the staircase, which operates via a lever system. This staircase can rotate upwards and downwards, allowing visitors to reach varying heights and achieve a closer view of the crater. With a total rotation of 30 degrees, the staircase provides flexible viewing angles that enhance the experience of the landscape.

Rotatable Structure
The building includes a rotatable base made from circular and square steel frames. This design allows for a complete 360-degree rotation around a central point. By enabling movement, the structure encourages visitors to appreciate the different views of Hverfjall. The design effectively combines accessibility with an immersive experience of the surrounding natural beauty.

Sheltered Spaces
At the base of the building, there is an inner space that offers shelter from inclement weather. This feature is important in Iceland's often unpredictable climate. The sheltered area allows visitors to stay comfortable and protected, making it possible to enjoy the site throughout the year. The design demonstrates an understanding of how architecture can respond to environmental challenges.

Roof Design
Taking inspiration from traditional Viking turf houses, the roof consists of a tensile structure that connects with the landscape. This design respects historical techniques while utilizing modern methods to ensure durability. The materials used, such as woven-coated polyester and Poly Tetra Fluoroethylene (PTFE), provide resistance against weather conditions. The roof contributes to the overall aesthetic and functional harmony of the structure with its rugged 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.
