## Project Overview

"The Constellations" is located in Iceland, a region renowned for its distinctive landscapes and celestial phenomena, such as the Northern Lights. The design incorporates multiple structures—including a Guest House, a Private House, and a Barn—arranged around a central courtyard. This configuration fosters a communal environment while offering diverse experiences for visitors. The project aims to create spaces that facilitate connections with both the surrounding natural beauty and the enchanting sky above.

### Spatial Strategy and Cultural Resonance

The design framework is influenced by Iceland’s rugged terrain and its history of turf house construction. By integrating locally sourced materials such as stone and earth, the project acknowledges traditional building methods while introducing modern amenities. The layout emphasizes site integration through open spaces optimized for stargazing and walking paths that encourage exploration. Architectural elements like large windows frame the sky, inviting a direct relationship between inhabitants and celestial events, thereby enhancing the user experience.

### Materiality and Sustainability

The selection of materials plays a crucial role in connecting the structures to their environment. Wood is used for structural beams, adding warmth to the interiors, while turf roofs provide natural insulation and blend with the landscape. Concrete contributes to thermal massing, supporting energy efficiency through geothermal heating systems. Extensive use of glass facilitates natural light and serves as a visual connection to the night sky. These choices prioritize sustainability, minimizing energy consumption and enhancing the symbiosis between the built environment and its natural surroundings.

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.
