The Black Lava Fields Visitor Center is located in the rugged landscape of Iceland, adjacent to Lake Mývatn and Hverfjall. It serves as a space for visitors exploring the volcanic terrain. The design reflects a thoughtful approach to human interaction with nature. Composed of two key elements—the Black Box and the White Surface—the center enhances the visitor experience while respecting the unique characteristics of the site.

Architecture Concept

The Black Box serves as the main functional area. It is a solid structure that houses essential visitor services. Its geometric shape draws from the local black lava, creating a strong connection to the surrounding landscape. In contrast, the White Surface wraps around the Black Box, forming a flexible space that encourages exploration and interaction. This design highlights the different ways visitors can engage with the center, whether they come with a specific purpose or a desire to wander.

Sustainability and Energy Use

A key aspect of the design is its use of local geothermal energy. This energy source powers the entire center, providing electricity and hot water. By relying on geothermal resources, the visitor center supports sustainability and reduces its environmental impact. This approach connects the operation of the building to the natural surroundings and reflects a commitment to responsible practices.

Visitor Experience and Engagement

The layout facilitates easy movement for everyone, including staff and visitors. The rooftop observation terrace offers expansive views of the landscape and features openings that reference the region's natural fumaroles. As visitors move to the terrace, they gradually reveal panoramic vistas, enhancing their connection to the site. This thoughtful design encourages visitors to engage with their surroundings in a meaningful way.

Materiality and Construction

The White Surface is made from ETFE film, a lightweight and durable material. This choice allows for adaptability and ease of maintenance while promoting natural light inside the building. The translucency of the ETFE film creates a changing atmosphere that connects visitors to the environment. Careful material selection contributes to a structure that performs well and complements the volcanic landscape.

The design includes openings that frame views of the stunning vistas, highlighting the careful consideration of sightlines and the relationship between the interior and the natural scenery.

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.
