CASA AEROLITO is located in Valle de la Luna, San Pedro de Atacama, Chile. The design responds to the challenges of a hot and dry climate while emphasizing sustainability and a strong connection to nature. The overall concept centers around efficient use of local materials and thoughtful strategies that create a comfortable living space in extreme conditions.

Spatial Organization

The layout is based on a main inclined volume that defines different functional areas. This approach encourages smooth movement between spaces, allowing for various activities to take place without feeling crowded. The kitchen and dining area are positioned to face the outside, promoting engagement with the landscape and family interaction. In contrast, the sleeping area offers privacy on a mezzanine, where occupants can gaze at the stars through a transparent surface.



Natural Integration

A courtyard serves as a bridge between the interior and the surrounding desert, enhancing both function and aesthetic appeal. Its proportions are matched to the main structure, creating harmony in the design. A semi-translucent feature envelops the courtyard, playing with light and shadow throughout the day. This thoughtful integration allows the changing sunlight to filter into the living spaces, providing warmth and a sense of openness.



Material Performance

Material choices are crucial for maintaining comfort in this climate. Earth is used as a primary building material, which helps regulate temperature by absorbing heat during the day and releasing it at night. The concrete plinth elevates the structure, protecting the earthen walls from rare but intense rainfall. This plinth also houses key systems, such as a water cistern and a passive purification process, both essential for sustainability in a water-scarce area.



Functional Spaces

The bathroom is strategically located between communal and private areas, ensuring it has its own distinct character. Thoughtful window placements allow natural light to enter and provide views of the landscape. The arrangement enhances each space's utility, including the sleeping room's focus on night sky observation. Each area contributes to an overall user experience that respects both the environment and the needs of its inhabitants.



The design captures light and space in a way that encourages interaction with the surrounding desert. Each detail reflects a commitment to creating a home that harmonizes with its setting while providing a refuge from the harsh climate outside.

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.
