The Al Wathba Wetland Reserve Flamingo Observation Tower is located in Abu Dhabi, designed to enhance how visitors connect with the natural environment. It serves to provide a space for observing the diverse wildlife inhabiting the wetlands. Rather than simply being a point to reach, the design highlights the journey that begins upon arrival at the reserve and culminates with an ascent to the top of the tower, offering broad views of the surroundings.

Structural Design

The tower is supported by reinforced concrete pad foundations that ensure an even distribution of weight across the wetland subsurface. This foundational system enhances the stability of the structure, making it resilient to the challenges typical in wetland areas.

Rising above these foundations are glu-laminated timber columns, standing at a height of 8.46 meters. These wooden columns create the main framework of the tower. Their exposure in the design not only adds strength but also allows them to visually connect with the landscape. The architectural expression is enhanced through this openness, creating a link between the built environment and the natural setting.

User Experience

Visitors ascend the tower via a spiraling ramp that offers changing perspectives as they climb. This design encourages exploration and engagement as each step reveals a different view of the wetland. The experience becomes more than just a climb; it allows visitors to immerse themselves in the landscape around them.

At the top of the tower, visitors are rewarded with wide-reaching views, providing many opportunities for wildlife observation. The design emphasizes both reflection and active engagement with the environment, allowing people to appreciate the thriving ecosystem from a unique vantage point.

Structural elements are integrated throughout to maintain a sense of transparency and openness. This design choice highlights the natural beauty surrounding the tower. The use of exposed materials brings attention to the connection between the structure and the environment, making the experience of visiting the observation tower both rich and meaningful.

`
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.
