The Ice-Cube Cabin, situated in Iceland's Krafla Crater, is designed to provide essential recreational and functional facilities for visitors within a landscape defined by volcanic and glacial features. The project prioritizes sustainable design principles to minimize environmental impact and respect the local cultural heritage, offering a contemporary architectural solution attuned to its unique context.

Spatial Strategy and Functionality

The cabin's design incorporates a double-skin facade, utilizing translucent polycarbonate and locally sourced timber, to enhance thermal performance and echo the geological strata of the surrounding environment. This design strategy ensures a comfortable interior climate during severe winter conditions while maximizing energy efficiency.

The cabin is spatially organized into two levels to optimize functionality. The ground level comprises an entry hall, information center, changing facilities, equipment storage, and rest areas. The upper level features a viewing platform and supplementary rest amenities, enhancing visitor engagement with the exterior environment.

Materiality and Sustainability

In alignment with environmental strategies, the cabin emphasizes the use of sustainable materials, including locally sourced timber, to ensure durability and minimize ecological footprint. Translucent polycarbonate panels are employed to maximize natural light penetration while preserving privacy, thereby reducing energy consumption. Geothermal energy systems are integrated to provide efficient heating and hot water, capitalizing on the region's natural geothermal resources. This integrated approach, combining local materials and advanced technologies, represents a considered architectural response to the region's unique and dynamic climate.

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.
