Earthen Shelter Featuring Thermal Mass Construction and Sustainable Sand Materials

Project in-detail

Constructed primarily from locally sourced sand and utilizing thermal mass techniques, the subterranean dwelling effectively maintains a stable internal climate while providing a comfortable living space in a challenging desert environment.
5 key facts about this project
01
Constructed eight meters below ground to utilize earth’s natural insulation.
02
Incorporates two courtyards to enhance light diffusion and ventilation.
03
Primary material is locally sourced sand, reducing environmental impact.
04
Employs passive cooling techniques for energy efficiency.
05
Designed to withstand extreme desert conditions while providing comfort.
The Sand House presents a distinctive architectural solution for residing comfortably in desert environments. Constructed primarily eight meters below the ground, the design capitalizes on the thermal mass of sand to maintain a stable internal climate, effectively reducing energy demand for cooling. By situating the living spaces underground, this project minimizes exposure to extreme outside temperatures and takes advantage of the earth's natural insulation properties. The architectural strategy is defined by functionality and sustainability, aiming to create a cohesive relationship between the built environment and its harsh landscape.

Utilizing locally sourced materials, the Sand House embodies a commitment to eco-friendly practices. The main structural component is sand, which is reinforced with concrete to provide stability. Wood elements are integrated into the design, particularly in the façade, to add warmth and a connection to traditional architecture. Glass placements are purposefully designed to enhance natural light penetration while minimizing solar glare. The overall layout features two courtyards that serve as light wells, promoting airflow and creating indoor-outdoor connections.

Thermal Performance and Functionality

The integration of subterranean living fundamentally alters how the occupants interact with their environment. By relying on passive cooling strategies, the Sand House effectively curbs the need for mechanical air conditioning. The design also includes areas dedicated to everyday living functions such as the kitchen, dining, and private bedrooms, ensuring a seamless flow between spaces. Each room is well-defined yet open, allowing versatility in how spaces can be utilized.

Architecture that Resonates with the Landscape

What distinguishes the Sand House from conventional residential designs is its fusion of modern architectural techniques with traditional materials and forms. The choice of sand not only speaks to the local context, but it also showcases an innovative approach to materiality that challenges typical construction methodologies. Furthermore, the incorporation of courtyards to manage light and ventilation is a notable departure from standard designs, allowing for a more nuanced experience of the interior environment.

For a comprehensive understanding of the architectural principles and design considerations that define the Sand House, interested readers are encouraged to explore detailed architectural plans, sections, and design elements. These resources will provide deeper insights into how the project addresses both the challenges of its geographical setting and the needs of its inhabitants through thoughtful architectural ideas.

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.
