### Overview
"Umskipti Hlutur" is a cabin designed for trekkers in the Icelandic wilderness, aimed at creating a space that facilitates both refuge and exploration. Set against the backdrop of Iceland's varied landscape, the project is conceived as a response to the duality of the environment—where natural beauty can evoke both comfort and challenge. The design emphasizes the importance of connecting users with their surroundings while providing necessary shelter and inspiration.

### Material Selection and Sustainability
The project utilizes locally sourced, sustainable materials to ensure harmony with the natural environment. Key components include wood used for the structural framework, which enhances warmth and tactile quality. Geothermal insulation harnesses Iceland’s natural resources, contributing to energy efficiency. Glass elements facilitate visual connections to the landscape, while a durable metal roof withstands Iceland's harsh weather conditions. The careful selection of these materials creates a balanced aesthetic, where the warmth of wood contrasts with the rugged textures of stone and metal.

### Spatial Configuration and User Interaction
Architecturally, the cabin features a distinct triangular form, optimizing wind resistance and allowing for vertical height that promotes openness and effective heat circulation. The interior space is designed with suspended hammocks, fostering comfort and a relaxed atmosphere. This layout encourages personal interaction with the environment, inviting occupants to engage with the breathtaking views through expansive windows. Layered, slatted wooden surfaces reflect light dynamically, creating an evolving interior experience throughout the day. Additionally, modular arrangements within the space support various activities, enhancing the overall user experience.

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.
