### Overview

Light Home is located in Iceland, designed as a multifaceted refuge that aligns with the rugged natural landscape while serving as a comfortable retreat for outdoor adventurers. The intent of the design is to enhance the experience of explorers, prioritizing accessibility, comfort, and sustainability in this remote setting.

### Spatial Strategy and Environmental Integration

The architectural approach emphasizes a strong connection to the Icelandic topography. Its cylindrical form responds to the geological features of the environment, promoting adaptability while minimizing the structure's impact on the landscape. The layout fosters a sense of openness, offering panoramic views of the dramatic surroundings through strategically placed large windows. This interaction between indoor and outdoor spaces encourages the infusion of natural light throughout the interior.

### Material Selection and Sustainability

The materials chosen for construction reflect a commitment to sustainability and practicality. Prefabricated concrete serves as the primary structural component, ensuring durability against challenging weather conditions. Large expanses of glass allow for abundant natural light and stunning vistas, while wood elements introduce warmth and texture to the interior finishes. The building incorporates innovative systems such as geothermal heating for energy efficiency, a water collection system for resource management, and a wind turbine for renewable energy generation. Additionally, the modular design allows for flexible reconfiguration to meet varying user needs, and communal spaces support social interaction among visitors, enhancing the overall experience of the setting.

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.
