Accumulating salt crystals on a steel veil reflects seasonal changes in the wetland, enhancing the visitor experience while promoting local biodiversity through elevated pathways and unobtrusive wildlife access.
5 key facts about this project
01
Accumulation of salt crystals on the steel facade enhances seasonal visual interest.
02
Elevated pathways allow unobstructed wildlife movement beneath the structure.
03
Metal pillars minimize visual impact while supporting the walkway.
04
Design adapts to wetland's dynamic water levels during winter months.
05
Focus on local biodiversity promotes ecological awareness among visitors.

The design at Al Wathba Wetland aims to enhance the natural beauty and ecological function of its diverse habitats while offering meaningful experiences for visitors. Located within a unique landscape of wetlands, the project focuses on supporting local wildlife, particularly the Greater Flamingo, while seamlessly integrating with the surrounding environment. The approach centers on accessibility and the preservation of natural features.

Elevated Pathways

The design includes elevated pathways and viewing platforms that allow wildlife to move freely beneath them. These walkways are supported by slender metal pillars, ensuring that the structures have minimal physical and visual impact on the landscape. The elevation provides visitors with a unique vantage point to observe the wetlands, creating an interaction with the habitat without intruding upon it.

Seasonal Adaptation

Seasonal changes play a significant role in the design. A steel veil is incorporated to respond to rising water levels during the winter months. This feature allows for the collection of salt crystals on the tower's facade, which visually reflects the wetland’s transformations. The structure adapts to the rhythm of nature, making the built environment responsive to its surroundings.

Material Choices

Materials selected for the project serve both functional and aesthetic purposes. Steel is used to provide structural strength while maintaining a clean, modern appearance. This choice of material is practical and supports the overall theme of environmental awareness, as it connects the built elements back to the natural landscape.

Delicate Details

The focus on details is evident in the design's interaction with the site. Pathways transition smoothly into the landscape, while the salt accumulation on the steel facade adds a dynamic visual element that changes with the seasons. This interplay between nature and the built environment creates an experience that highlights the relationship between architecture and ecology, encouraging visitors to engage with the wetland in a thoughtful way.

`
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.
