## Overview
The Prolonged Journey cabin is situated in the diverse landscape of Iceland and is designed to provide an immersive experience for trekkers in the region. The goal of this project is to create a space that not only serves as shelter but also enhances the interaction between occupants and the natural environment, allowing for a deeper connection to the rugged terrain.

## Spatial Arrangement
The design employs a “Knot” concept, emphasizing communal living and interaction among trekkers. The layout comprises distinct functional zones, including a kitchen, sleeping quarters, communal areas, bathrooms, and storage to support a range of activities. Large glass panels are integrated into the design to bring in natural light and offer views of the surroundings. The “Observation Bridge” enhances the experience by providing elevated viewpoints, while modular sleeping areas adapt to the needs of various occupants, promoting social engagement and shared experiences.

## Material Selection
A careful selection of materials reflects the local context and the climatic challenges of the Icelandic environment. Timber cladding, likely sourced from local forests, provides both aesthetic and protective qualities. Extensive use of glass promotes natural light and connectivity with the outdoors. Reinforced concrete is utilized for structural integrity, while natural stone elements, such as basalt or granite, contribute to both functionality and thermal efficiency. Additionally, plywood is employed inside for furnishings, offering warmth and durability. The integration of geothermal heating systems underscores a commitment to sustainability and environmental responsibility.

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.
