## Overview

The trekking cabins project comprises a series of modular units designed for use in rugged terrains, particularly in climates such as Iceland. This design responds to the needs of outdoor enthusiasts by providing functional living spaces that facilitate an immersive experience with nature while offering protection from the elements. The architecture draws inspiration from the form of a caterpillar, suggesting adaptability and continuity along trekking paths.

## Spatial Configuration and User Experience

The layout of the cabins follows a linear arrangement, which emulates the paths trekkers navigate. This modular design fosters versatility, allowing for various configurations that promote a sense of community among users. The units are strategically rotated at 45 degrees, creating a zigzag profile that optimizes airflow and natural light while enhancing visibility and connection to the surrounding landscape. Elevated slightly off the ground, the cabins facilitate natural drainage and delineate private spaces effectively.

### Material Sustainability and Environmental Integration

The project incorporates a thoughtful selection of materials to ensure durability and comfort. Concrete is utilized for the exterior facade, offering resilience against extreme weather, while warm-toned wood is used within interior spaces to create a welcoming atmosphere. High-performance insulation materials are integrated to maintain thermal comfort across seasons.

Sustainability measures include rainwater harvesting systems that reduce reliance on external water supplies, as well as geothermal heating that leverages local resources. Materials are sourced locally to minimize the carbon footprint and support regional economies. The design fosters safety and convenience, with provisions for bicycle storage integrated into the elevated structure, promoting an active lifestyle among trekkers.

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.
