The Dimmuborgir Visitor Center is situated in Iceland, known for its unique geological features and volcanic history. The center enhances visitor engagement with the landscape, serving as a space for education and a connection to the natural environment. The design concept draws inspiration from the characteristics of the site, particularly the forms of Hverfjall volcano and the fissures in the nearby lava fields, allowing visitors to appreciate the region's geography deeply.

Architectural Concept

The visitor center includes two distinct buildings: an exhibition space that informs visitors about the area's geological history and a café for relaxation. The center's layout features a promenade leading visitors to various destinations, encouraging an explorative attitude toward the surrounding landscape.

Accessibility and Interaction

Accessibility is an important aspect of the design, implemented through boardwalks, sloped paths, and ramps that navigate the rugged terrain. This thoughtful approach enhances movement around the site while inviting visitors to engage with the natural features from different angles.

Structural Design and Materiality

The roofs of the buildings are designed to reflect the geological context. One building presents an open and inviting form, while the other appears more solid, echoing the heavier geological elements found in the area. Materials are chosen to reflect local characteristics, with the roofs designed to resemble larger lava flows and incorporating silica composite materials sourced from the lava itself. This choice strengthens the connection between the architecture and its setting.

Visitor Experience and Narrative

Interior circulation in the visitor center is focused on enhancing the visitor experience, drawing inspiration from volcanic chambers and the flow of magma. This narrative encourages connection with the landscape's geological history. The exterior pathways play a crucial role, linking trails that guide visitors toward Hverfjall, creating a cohesive relationship between the built environment and the natural surroundings.

A ramp integrates with the café, providing access to a rooftop observation area. This design feature offers visitors expansive views of the surrounding terrain and invites them to take a moment to appreciate the volcanic landscape.

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.
