Earth Sheltered Retreat Featuring Passive Cooling and Rammed Earth Construction

Project in-detail

Incorporating rammed earth construction and a sunken courtyard for passive cooling, this retreat maximizes thermal efficiency while providing a serene living space within a harsh desert environment.
5 key facts about this project
01
Incorporates a sunken courtyard that optimizes natural cooling and minimizes direct sunlight exposure.
02
Utilizes locally sourced rammed earth for high thermal mass and energy efficiency.
03
Features a wind-catcher design that enhances airflow and indoor comfort.
04
Integrates native vegetation around the structure to improve the microclimate.
05
Employs an orientation strategy to maximize passive solar heating during winter months.
The architectural project "Shadow of the Sand" is designed for an arid desert environment, focusing on sustainable practices and climate-responsive design. It integrates traditional and contemporary architectural principles to create a functional living space that provides relief from high temperatures while fostering a strong connection to the landscape. This design emphasizes passive cooling strategies and natural materials, addressing the challenges posed by the desert climate effectively.

Sustainable Materials and Construction Techniques

One of the defining characteristics of "Shadow of the Sand" is its use of locally sourced, sustainable materials. Key components include reinforced rammed earth for walls, concrete for structural integrity, wood for aesthetic finishes, glass for natural lighting, gravel for enhanced thermal performance, and metal for structural reinforcement. Each material is carefully selected to contribute to energy efficiency and the overall durability of the structure. The integration of these materials showcases a commitment to sustainability while maintaining alignment with regional building traditions.

Innovative Design Elements

"Shadow of the Sand" incorporates unique design approaches that distinguish it from conventional desert architecture. The sunken courtyard is central to the design, serving as a passive cooling mechanism by capturing breezes and reducing sun exposure. The architectural layout is oriented to maximize views and facilitate cross-ventilation between spaces.

Additionally, the inclusion of a wind-catcher enhances indoor air quality by drawing in cool breezes, significantly contributing to thermal comfort. The careful arrangement of rooms around the central courtyard creates a communal atmosphere while maintaining individual privacy, appealing to both social interactions and personal retreat.

Environmental Considerations and Lifestyle Integration

The project highlights environmental responsiveness through its architectural design strategy. By utilizing passive solar design, it minimizes reliance on mechanical cooling systems, reducing energy consumption. The landscaping around the structure is also designed to further enhance the microclimate, with vegetation strategically placed to provide shade and improve air quality.

"Shadow of the Sand" is not only a feature of architectural innovation but also an embodiment of how design can thoughtfully integrate with its environment. The project invites exploration of its architectural plans, sections, and design elements. For a comprehensive understanding of how each aspect interrelates to produce a cohesive architectural experience, examining the project presentation is encouraged, as it provides deeper insights into the architectural ideas that form the foundation of this unique design.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
