HRAUN STRAUMUR, meaning "Lava Stream," is situated in Iceland, a country known for its dramatic geological features, including volcanoes and rugged landscapes. The design integrates the building with the gentle slope of the terrain, creating a low-lying oblong structure that protects visitors from strong winds. It provides a clear distinction between the functional northern side and the picturesque views to the south.

Conceptual Framework

The design focuses on the visitor's journey. Upon arrival, guests transition from vehicles to a covered walkway. This walkway features a wall that mimics solidified lava, creating a unique interaction with the landscape. As visitors walk along this path, they experience filtered views, adding a sense of curiosity and connection to their surroundings.

Spatial Organization

The layout consists of a single level, which simplifies the arrangement of various spaces, such as exhibition rooms, a cafeteria, and offices. Smaller rooms are located towards the north for efficiency, while larger, flexible spaces face south and west to take advantage of natural light. This configuration supports various functions and enhances the overall visitor experience.

Material Palette

The project uses black stabilized aluminum foam known as "Alusion" as its main exterior material. This lightweight material resembles lava's appearance, reinforcing the connection between the building and the local geology. Additionally, basalt floor tiles are integrated into the interior spaces, ensuring a consistent visual theme throughout the museum.

Design Detailing

A notable feature is the cafeteria, which extends outward and includes large window bands. This design invites visitors to view the surrounding landscape while they eat and relax. The openness blurs the line between inside and outside, fostering a closer relationship with the natural environment.

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.
