## Overview
Located in Iceland’s dynamic terrain, the Ice Pod is designed as a lightweight and sustainable accommodation for trekkers and adventurers. The structure draws inspiration from natural landforms, particularly icebergs, with a form that minimizes environmental impact while prioritizing usability and comfort. The design integrates seamlessly into the landscape, offering a functional refuge for those exploring the rugged Icelandic wilderness.

## Spatial Organization
The Ice Pod features a compact layout of approximately 60 square meters, strategically organized to enhance both communal and private experiences. The central living space is versatile, accommodating various activities with adaptable furniture options, including customizable sleeping platforms and storage solutions. The kitchen area is equipped with essential amenities and designed to utilize drone-delivered gas supplies. Sleeping quarters provide comfort and expansive views of the surroundings through integrated hammocks and platforms, fostering a close connection to the natural environment.

## Material and Technological Integration
Emphasizing lightweight yet durable materials, the Ice Pod utilizes super-insulated sandwich panels for thermal efficiency, a lightweight steel frame for structural integrity, and engineered wood for interior surfaces, which introduce warmth into the design. Advanced technology is integral to the project, featuring renewable energy systems, including geothermal energy and rainwater collection, to ensure a self-sufficient operation. Smart cabin technology allows for user connectivity and resource management via an app interface. Moreover, the design's modularity permits the addition or removal of units to accommodate varying group sizes and purposes, aligning with sustainable practices and reducing waste.

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.
