Sand-Pneumatic Structure Embracing Local Materials for Enhanced Thermal Efficiency

Project in-detail

Utilizing a sand-pneumatic construction method, this residence integrates locally sourced materials and innovative thermal strategies to create an environmentally responsive dwelling that capitalizes on the unique challenges of desert living.
5 key facts about this project
01
Utilizes a sand-pneumatic construction method for lightweight structural integrity.
02
Incorporates local sand as the primary building material, minimizing environmental impact.
03
Features transparent pressurized airbags that serve as both insulation and natural lighting.
04
Employs passive cooling strategies through a wind tower and integrated thermal mass.
05
Designed with a curvilinear shape to optimize natural airflow and energy efficiency.
The 99% Sand House is a contemporary architectural project that embodies sustainable design principles while addressing the challenges of living in a desert environment. Constructed primarily using locally sourced sand, this house integrates traditional forms with modern technologies to create a dwelling that is both functional and responsive to its climatic context. The structure's distinctive form combines aesthetic appeal with energy efficiency, demonstrating how architecture can harmonize with nature.

Design Concept and Unique Approaches

This project leverages a design approach that prioritizes local materials and environmental considerations, with 99% of the structure made from sand. The utilization of sand not only minimizes the carbon footprint associated with material transportation but also enhances the building's thermal performance and noise insulation properties. The architectural design reflects a modern interpretation of desert dwellings, with a slender, curvilinear silhouette that captures natural light while promoting passive cooling strategies.

A key feature of the 99% Sand House is its innovative use of synthetic materials. The remaining 1% of the structure is comprised of a lightweight, durable outer skin that enhances the building’s ecological profile. Transparent pressurized airbags serve as both glazing and insulation, facilitating daylight entry and ventilation, greatly reducing reliance on mechanical cooling systems. These design elements emphasize a blend of aesthetics and functionality that is not commonly seen in traditional desert architecture.

Architectural Details and Functionality

The interior layout of the 99% Sand House is organized around an open-concept design that promotes communal living while providing flexibility for various functions. Natural materials are employed within the interior space, creating a cohesive relationship with the environment outside. The arrangement maximizes the connection to the arid landscape and allows for an adaptable living space, which is essential in climates where energy efficiency is critical.

This project includes several energy-efficient strategies embedded into its design. The passive cooling system utilizes double-layer airflow channels, enhancing indoor comfort without the need for excessive energy consumption. A combined water storage and cooling system stabilizes indoor temperatures, taking advantage of thermal mass principles to create a comfortable living environment.

In summary, the 99% Sand House demonstrates a comprehensive approach to architectural design, merging sustainable materials with innovative functionalities. The thoughtful integration of passive design techniques, local resources, and modern technologies underscores the project’s commitment to environmental stewardship and efficiency.

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.
