Located at the foot of the Hverfjall crater in Iceland, the Hverfjall Visitor Centre serves an important role for those exploring the area’s unique geological features. The design embodies a semi-earth bermed curvilinear form, carefully planned to blend with the surrounding volcanic landscape. By prioritizing harmony with nature and enhancing the visitor experience, the structure offers both functional space and an appreciation of the environment.

Structural Form and Materiality

The two-story building relies on mass timber posts and beams for its structural support, ensuring a solid and durable form. The high-performance glass storefront allows natural light to flood the interior, promoting visibility to the stunning views outside. This design choice creates a strong connection between the inside of the building and the beauty of the landscape, making it feel open and inviting.

Passive Solar Design

At the core of the design is a trombe wall made from gabion baskets filled with local rock. This element plays a key role in managing the building's thermal performance while also harnessing solar energy. The substantial thermal mass stores heat during the day and releases it slowly at night, helping to maintain a comfortable environment. The trombe wall is intentionally lower than the ceiling, allowing clerestory windows to bring in light and enhance air circulation.

Functional Zones and Circulation

Inside, the Hverfjall Visitor Centre is thoughtfully divided into four separate areas, each serving a different purpose for guests. The upper level contains a coffee shop and a welcome desk, making it easy for visitors to check in. The lower level features restrooms and exhibition spaces with direct access to a central courtyard. This courtyard can host a variety of activities, from informal gatherings to educational displays related to the natural surroundings.

Design Integration with Landscape

The roof of the building slopes toward the central courtyard, aiding rain and snow runoff while keeping the design respectful of the natural ridgeline. Entry points are carefully placed to allow for smooth visitor flow, guiding people through the space while maintaining a sense of connection to the outdoor environment. Natural colors and textures within the interior design align with the local landscape, creating an atmosphere that encourages exploration and reflection.

Five wooden boxes serve as view portals, framing scenes of the landscape outside and providing heated seating areas. These nooks invite visitors to pause, enjoy warmth, and take in the surrounding beauty.

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.
