### Overview

Located in arid regions, Desert Hyacinth is designed to redefine residential living through innovative architectural strategies that prioritize sustainability and climatic adaptability. The intent of the project is to create a harmonious balance between modern functionality and cultural heritage while addressing the extreme temperatures characteristic of desert environments.

### Spatial Composition and Functional Design

**Zoning and Layout**
The spatial organization strategically divides the residence into distinct zones: private, semi-private, and service areas. This layout maximizes natural light and promotes cross-ventilation, providing comfort while reducing reliance on artificial lighting and cooling systems. The ground floor includes communal areas—such as a living room and dining space—with direct outdoor access, integrating nature into daily living. In contrast, the first floor accommodates private spaces, designed to ensure individual privacy while maintaining connectivity through shared balconies.

**Mashrabiya and Facade Elements**
The project features a contemporary adaptation of the traditional mashrabiya, providing essential shading and privacy. The northern facade incorporates decorative shading elements and integrated planters to enhance cooling and aesthetic appeal, with color transitions reflecting the palette of local desert flora. This not only contributes to the building's identity but also supports thermal regulation.

### Material Selection and Environmental Considerations

**Sustainable Materials**
Careful material selection underscores a commitment to environmental sustainability. The structure predominantly utilizes concrete for durability, glass for natural illumination, and metal mesh for dynamic mashrabiya elements. Vegetative coverings are included to enhance cooling, while photovoltaic panels are integrated for energy efficiency. These materials are chosen for both their performance characteristics and their ability to contribute positively to the overall aesthetic.

**Ventilation and Energy Efficiency**
The design implements natural ventilation strategies based on traditional architectural practices, utilizing thermal dynamics through ceiling openings. Computational Fluid Dynamics (CFD) analysis informs the design, optimizing airflow and enhancing occupant comfort. Significant energy savings are achieved through effective daylight management, with strategically placed windows and shading devices that control glare while promoting livability. Additionally, kinetic energy storage systems and evaporative cooling techniques further enrich the building's environmental performance, ensuring indoor climate regulation with minimal energy use.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
