**Overview**

The Trekking Cabins are situated in Iceland, an environmentally distinct location that presents both opportunities and challenges for architectural design. The project aims to establish a functional shelter for trekkers, incorporating elements of traditional Icelandic architecture alongside contemporary sustainable building practices. This design responds to the local climate and cultural context, emphasizing efficiency and environmental stewardship.

**Site Strategy and Spatial Configuration**

The cabins are strategically located to maximize the capture of natural resources, such as solar energy and wind. The arrangement of windows and structural elements is calibrated to enhance interaction with the surrounding landscape. The layout promotes communal living, featuring shared spaces such as a living area and kitchen, alongside private sleeping quarters. This configuration encourages social connectivity among visitors while providing the necessary comforts for a nature-oriented experience. Additional design features include roof elements that effectively channel rain and snow, supporting water management systems integral to the site’s ecological balance.

**Material Selection and Sustainability**

The design utilizes a diverse palette of locally sourced materials, including timber for exterior cladding, concrete for structural walls, and aluminum for energy-efficient glazing. The selection of stone connects the cabins to the geological context, emphasizing craftsmanship while ensuring durability against Iceland’s harsh weather. Protective finishes that are environmentally safe extend the life of interior surfaces. Renewable energy strategies are embedded in the design, including geothermal heating, wind turbines, and solar panels, ensuring minimal ecological impact and fostering energy independence. Rainwater harvesting systems further enhance the project's commitment to sustainability, promoting responsible resource usage.

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.
