The design integrates harmoniously with its surroundings, presenting a structure that embraces the interplay of light and shadows. Located within a landscape that highlights this duality, the building serves as a home while exploring the depths of human experience. The central concept revolves around two symmetrical voids known as "day" and "night," which are positioned against a long thermal rammed earth wall. This framework promotes a smooth flow between inside and outside spaces, encouraging a rich interaction with various light conditions.

Conceptual Framework

At the heart of the design is a balance between light and darkness, inviting users to appreciate both elements. The elongated thermal rammed earth wall acts as a focal point, establishing a visual connection between the voids. This setup encourages inhabitants to navigate through the house, reminding them of the cycles of life and how perception of light is enhanced through contrast with darkness.

Spatial Organization

Inside, the layout is thoughtfully arranged around a central courtyard, promoting movement and connection between different areas. The journey begins in the work space and living room, progresses through the kitchen and dining room, and intentionally sidesteps the bathroom, allowing for a more open flow. This sequence reflects everyday life and cultivates a sense of continuity throughout the spaces.

Light and Atmosphere

Vertical movement within the design reveals an engaging play of light and shadow. As occupants descend into the structure, the atmosphere changes, enriching their experience. The bedroom features a large opening to the night sky, which brings in soft moonlight and stars. This connection to the celestial adds a peaceful quality to the space, fostering relaxation and quiet reflection.

Materiality and Sustainability

Employing thermal rammed earth as a primary material supports both structural stability and energy efficiency. This choice aligns with sustainable practices, blending the building with its landscape while promoting indoor comfort. The material also assists in regulating temperature throughout the interior, underscoring a commitment to environmental considerations.

Over the central courtyard, a carefully designed skylight allows sunlight to filter down, creating a beautiful play of light patterns across the interior spaces throughout the day.

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.
