Hverfjall Hearth is located within the dramatic landscape of Hverfjall Crater, designed to be a place of shelter and comfort in a difficult environment. The central idea focuses on the need for warmth, reflecting a fundamental human desire for safety and tranquility. The building contrasts the cold, harsh qualities of the surrounding area with a welcoming and cozy interior.

Design Concept

The entrance is thoughtfully designed to look like an earthen fissure that releases steam, emphasizing the weight of the harsh external conditions. As visitors step inside, they are met with expansive views of the barren landscape, enhancing the feeling of transition. This design element prepares them for the comfort offered as they enter the café area, where they can finally relax.

Café Space

The café serves as the heart of Hverfjall Hearth, encouraging visitors to gather and providing a peaceful retreat. The layout is open and accessible, allowing for easy movement between areas. Inside, the atmosphere is warm and inviting, a noticeable contrast to the challenging weather outside. It creates a refuge for those seeking a break from their travels.

Exhibition Area

The exhibition space aims to deepen the connection between visitors and Hverfjall Crater. Instead of traditional displays, the area invites guests to engage with the landscape on a more personal level. The architecture fosters a sense of exploration, encouraging visitors to consider the crater’s unique characteristics and the ever-changing environment.

Materiality

Key materials in the construction include rigid insulation, an aluminum plate roof, oxidized steel cladding, wood finish flooring, and radiant heat tubing. These elements contribute to the building's stability and energy efficiency while reflecting the rugged beauty of the landscape.

The design emphasizes the connection between people and their surroundings. It creates a comfortable space that acknowledges and responds to the challenges presented by nature.

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.
