3D Printed Sand Blocks and Passive Cooling Strategies in Sustainable Desert Housing

Project in-detail

Utilizing 3D printed sand blocks and passive cooling techniques, the design creates an energy-efficient and adaptable living space within the demanding climate of the UAE.
5 key facts about this project
01
Utilizes 3D printed sand blocks made from local materials for enhanced thermal performance.
02
Incorporates wind towers to facilitate natural ventilation and cooling throughout the structure.
03
Features a central courtyard that serves as a passive cooling element and communal gathering space.
04
Designed for future expandability, allowing adaptation to changing family needs.
05
Integrates biophilic elements with native vegetation to create a sustainable outdoor environment.

The architectural design project "Reproduction of Legacy" is situated in the United Arab Emirates and embodies a synthesis of traditional Middle Eastern architectural elements with modern construction techniques. A key focus of this project is addressing the harsh climatic conditions of the desert while providing a functional living space that enhances the quality of life. The design incorporates a range of sustainable practices and innovative materials, emphasizing energy efficiency and ecological responsibility.

The project consists of an interconnected series of volumes that mimic the natural landscape of sand dunes, designed specifically to optimize shading and protect from extreme heat. Central to the layout is a courtyard that serves as an environmental buffer, facilitating natural ventilation and reducing reliance on mechanical cooling systems. This design choice promotes an inviting atmosphere for both residents and visitors.

Integration of Traditional Design Elements

A hallmark of the "Reproduction of Legacy" project is its thoughtful incorporation of traditional design elements, such as wind towers and courtyards. These features are historically significant in providing passive cooling in warm climates. The layout encourages airflow, where the cool air is drawn into living spaces and warm air escapes through high-level openings. This method enhances comfort while minimizing energy consumption.

The materiality of the structure is particularly noteworthy. The project utilizes 3D printed sand blocks for walls and façades, which establish a thermal buffer and engage with local resources. Precast concrete panels are employed strategically to balance structural efficiency and construction time, while specially designed roof blocks facilitate water management and temperature regulation. This approach supports sustainability by utilizing local materials and enabling off-site construction, thereby reducing the carbon footprint associated with traditional building methods.

Community and Expandability Focus

Beyond its functional and energy-efficient design, "Reproduction of Legacy" places a strong emphasis on community interaction and adaptability. The configuration of the interior spaces allows for easy adaptability according to the occupants' needs. Communal areas are designed to promote family engagement, while the private spaces offer privacy and comfort. The home accommodates future expansions, a crucial aspect that resonates with the dynamic nature of modern family structures.

The outdoor spaces, including gardens and terraces, are designed with local flora in mind, creating biophilic connections for occupants. These elements not only enhance the aesthetic value but also contribute to the ecological sustainability of the home.

The "Reproduction of Legacy" project exemplifies contemporary architecture's role in promoting sustainability, cultural relevance, and community-oriented design. To gain deeper insights into this architectural endeavor, including architectural plans, architectural sections, and overall architectural ideas, readers are encouraged to explore the comprehensive project presentation available for detailed examination.

The Mujassam Watan Urban Sculpture Challenge invites architects and designers to create iconic public sculptures for one of two sites in Saudi Arabia: Abu Hadriyah Road or the Tharwa Sea Front in Al-Khobar. Proposals should reflect Saudi identity, culture, and future aspirations.

`

The Mujassam Watan Urban Sculpture Challenge is an international architecture and design competition inviting creatives to shape the future of Saudi Arabia’s public spaces. With a total prize fund of €50,000, the competition calls for sculptural proposals that merge cultural symbolism with innovative design, offering participants a chance to see their concepts brought to life in a rapidly transforming national context.

Organised by Buildner in partnership with the Mujassam Watan Initiative, the challenge focuses on two prominent locations: Abu Hadriyah Road, a major highway and gateway into the Eastern Province, and the Tharwa Sea Front in Al-Khobar, a pedestrian-focused waterfront district. Designers must select one site and develop a sculpture that engages with its surroundings—whether addressing the fast-paced dynamism of a transit corridor or creating moments of interaction along a coastal promenade.

Proposals should be bold, site-specific, and rooted in narrative—drawing on themes such as heritage, national identity, transformation, and dialogue. Environmental responsiveness, material durability, and feasibility are strongly encouraged, as winning projects may be selected for actual construction.

Each submission must include four A2 landscape presentation boards, a cover image, and a written project description. The competition is open to professionals and students alike, working individually or in teams of up to four people. No professional license is required.

Registration is open until July 24, 2025, with final submissions due by August 27, 2025. Winners will be announced on October 1, 2025.
