MIRAGE is situated in the Al Wathba Reserve, designed to enhance the experience of visitors while fostering a connection with the surrounding nature. It draws on traditional Arabic architecture, using geometric forms that reflect the cultural context. The spiraling structure invites exploration and interaction, encouraging visitors to observe the local birdlife.

Design Concept and Aesthetics

The tower's shape resembles a dome when viewed from a distance, connecting it to the region’s architectural traditions. As one approaches, the spiral form rises from the ground, inviting curiosity and engagement. This pathway not only serves as a means to reach the observation platform but also offers dynamic views of the landscape and its flora and fauna. The design encourages a sense of discovery, as visitors move through the space.

Structural Composition

MIRAGE achieves its stability through a system of wooden assemblies that allow for intricate shapes while ensuring structural soundness. The lightweight appearance contributes to a sense of floating above the desert floor. Using wood in construction assists in maintaining balance and elegance in the overall design. Each component plays a role in creating a harmonious interaction with the environment.

Material Selection

The exterior of MIRAGE features smooth cast plexiglass, specifically CN AltuglasⓇ. This material is important for creating the mirage effect, providing transparency while reducing glare. It allows visitors an unobstructed view of the landscape while also protecting them from intense sunlight. The choice of materials supports both the functionality and aesthetic of the tower, blending it into the natural setting.

Visiting Experience

An observation platform at the top provides a full view of the surrounding area, enriching the experience for visitors. The spiral path includes shaded spots for resting, inviting people to stop and reflect on the beauty and significance of the reserve. This thoughtful design connects visitors not only to the architecture but also to the natural environment, making it an engaging place to visit.

Along the façade, geometric patterns echo traditional motifs, adding cultural depth while the spiraling form works with the landscape's contours. This relationship fosters a dialogue between the environment and the design, enriching the overall experience for visitors.

`
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.
