The Iceland Volcano Museum (IVM) is a cultural institution designed to educate visitors about the unique volcanic landscape of Iceland. It connects indoor and outdoor spaces through a central void that serves as a key element of the design. This central area encourages movement and engagement, creating an environment that invites exploration and interaction with the exhibits.

Design Concept

This design focuses on establishing a connection between the interior spaces and the surrounding landscape. The central void promotes movement and visual links between various sections of the museum. On the ground floor, the main exhibition hall takes center stage alongside essential visitor services like the reception, restrooms, and information points. This layout ensures that guests can navigate the museum easily.

Functional Spaces

Visitor experience is a top priority in the layout. Clear circulation routes lead to key areas such as the museum hall and exhibition corridors. The design includes necessary support spaces, such as a cloakroom and a technical room for exhibition storage, which enhance the museum's operations while ensuring visitor comfort.

Exhibition and Educational Areas

The lower floor offers additional educational features, including a waiting area and changing rooms for volcanologist suits. These clearly underline the museum's focus on experiential learning. By providing access to a volcanic garden, visitors can connect directly with the natural environment, enriching their understanding of geological phenomena.

Design Details

One notable feature is the café, a structure made primarily of glass, positioned 12 meters away from the volcanic garden. This design choice invites visitors to take in views of the landscape while enjoying refreshments. The café also has a green roof that supports local ecology, further linking the building to its environment. Such details show a commitment to thoughtful design that enhances both the visitor experience and the museum's educational mission.

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.
