Constructed with charred timber and an ETFE membrane, this cabin integrates sustainable design elements to provide a functional retreat for trekkers in the Icelandic landscape.
5 key facts about this project
01
Constructed with charred timber for enhanced durability and aesthetic warmth.
02
Utilizes an ETFE membrane for light diffusion and energy efficiency.
03
Features a bent A-frame design that optimizes structural integrity.
04
Incorporates geothermal heating to minimize energy consumption.
05
Designed with modular elements for efficient assembly and local adaptation.

### Project Overview

The Trekking Cabin is located in a geothermal region of Iceland, informed by the unique properties of solfataras, where steam naturally rises from the earth. The structure features an oblique, semi-transparent form that interacts dynamically with its rugged surroundings. It is designed to serve as a refuge for trekkers and explorers, facilitating both comfort and a strong connection to the surrounding landscape.

### Design and Materiality

The cabin incorporates a diverse range of materials, chosen for their durability, aesthetic qualities, and energy efficiency. Key elements include an ETFE membrane that allows for light diffusion while providing structural integrity, and charred timber, which enhances the interior warmth and offers fire resistance while alluding to traditional Icelandic building practices. Polycarbonate panels improve insulation and permit abundant natural light, while isolation wool optimizes thermal comfort, adapting to Iceland's variable climate. The foundation comprises concrete and prefabricated piles, ensuring stability against harsh weather conditions.

### Functional Layout and Technical Solutions

The cabin's circular layout promotes ease of movement and interaction among users. Dormitories accommodate communal sleeping arrangements with private areas, and multiple bathing facilities enhance user comfort. Kitchen and dining areas are strategically positioned to foster communal dining experiences. Technical facilities are included for gear storage and laundry needs.

Sustainability is addressed through geothermal heating, utilizing natural earth heat for year-round warmth; rainwater collection systems promote resource efficiency; and solar panels harness energy for off-grid operations. This design balances functionality with a commitment to sustainability, reflecting a holistic approach to architecture in a challenging environmental context.

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.
