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.

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.
