The AROUND Ice Land Black Lava Fields Visitor Center is positioned within the rugged landscape of northern Iceland, facing the Hverfjall volcano and the calm waters of Lake Mývatn. Designed to serve visitors, the building combines education and recreation while reflecting the area's natural features. The round shape of the structure harmonizes with the environment, encouraging a connection between visitors and the landscape. This design promotes exploration and interaction, providing essential services in a thoughtful manner.

Building Form and Layout

The center's circular design creates a unified and consistent form that fits with the broad landscape. This choice ensures that the building aligns visually with the surroundings, enhancing the experience as one approaches it. The layout focuses on a landscaped courtyard, which helps foster communication among visitors and facilitates movement throughout the space. Curved observatory stairs allow for clear views of the landscape, drawing attention to the beautiful scenery and promoting an inclusive atmosphere.

Interior Functionality and Spatial Experience

Inside, the visitor center includes various spaces such as an information center, kitchen, café, and an observatory area, alongside a designated play area for children. The design incorporates different ceiling heights to enhance the spatial experience. Public areas boast ceilings that rise to six meters, creating a feeling of openness and airiness, while staff regions feature lower ceilings conducive to work. This approach improves light distribution and creates a welcoming atmosphere, important in a location with frequently changing weather.

Material Selection and Technical Considerations

Selecting appropriate materials supports the building’s performance under local weather conditions. Some of the materials used include 2mm aluminum capping, ventilation grilles, steel and concrete roof slabs, dark grey fascia, white ceilings, and laminated glass. The roof's ventilation grilles help manage snow accumulation, reducing the risks associated with rapid melting and ensuring the structure's reliability during winter. These practical choices contribute to the building’s overall functionality and visual appeal.

The observatory stairs also serve as a playground for children, allowing them to play while engaging with their surroundings. This design element reflects the adventurous spirit of the nearby black lava fields, encouraging children to connect with the natural environment. It highlights a thoughtful approach to blending recreational spaces with architectural form, ultimately enhancing the visitor 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.
