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.

Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.
