04
Design includes a Majilis, reflecting traditional Emirati cultural values.
05
Employs passive cooling techniques adapted to the specific climate of Nad Al Sheba.
The Sand End House is an architectural project located in Nad Al Sheba, designed to reflect contemporary Emirati living while integrating traditional practices with innovative materials and construction techniques. This residential design stands as a model of sustainability and adaptability, tailored specifically to the climate and cultural nuances of the region. It emphasizes the use of locally sourced materials, particularly desert sand, and incorporates elements intended to enhance both functionality and aesthetic appeal.

Design Objectives and Functionality

Central to the project is its multifunctional design that caters to both private living and community gatherings. The incorporation of a Majilis, a traditional gathering space, enhances social dynamics while maintaining a strong emphasis on family interaction. The layout optimizes natural light and ventilation, crucial for comfort in the Emirati climate. The design also includes an indoor garden, functioning as a natural buffer and improving indoor air quality.

The architectural form utilizes a central wind tower, serving as a passive ventilation system. This innovative feature captures natural wind currents, promoting airflow throughout the living spaces. Cross-ventilation is further facilitated through strategically placed windows, mitigating the need for mechanical air conditioning.

Sustainable Practices and Unique Materials

One of the key innovative aspects of the Sand End House is its use of desert sand, which is not only abundant but also serves significant structural roles. By leveraging the properties of sand bacteria (Sporosarcina pasteurii), the design achieves durability in its walls through a biological bonding process. This method exemplifies an advanced understanding of material science within the context of architecture, prioritizing ecological responsibility and local resource utilization.

The selection of materials extends beyond sand to include reinforced concrete and natural wood for finishes. These materials are chosen for their thermal properties and cohesiveness with local construction traditions. The result is a home that resonates with culturally significant practices while meeting modern standards of performance.

Architectural Features and Technical Innovations

Distinct elements of the Sand End House include adaptive roof projections and shaded outdoor areas that enhance the performance of the building envelope. The roof design not only contributes to aesthetics but also serves critical roles in passive cooling by reducing solar gain. The careful planning of overhangs and shading devices addresses the challenges posed by the extreme temperatures of the region.

Additionally, the interior spaces are designed with flexibility in mind, allowing for customization to meet the varied needs of residents. The incorporation of modern technologies, such as customizable cooling systems, supports the design's commitment to efficiency and comfort.

For those interested in exploring this architectural project further, detailed examinations of the architectural plans, sections, and design concepts reveal the complexity and thoughtfulness in every aspect of the Sand End House. Such insights facilitate a deeper understanding of both the project’s functional design and the innovative strategies employed to create a sustainable living environment.
