"Infobricks" provide educational information about local flora and fauna.

The Al Wathba Wetland Reserve is located within a distinctive desert landscape, where the design aims to bring together architecture and its natural surroundings. The space serves the public by offering a place for exploration and interaction. The overall design concept prioritizes a reduced ecological impact while making use of local resources. Central to the design is the use of sand, which influences the visual and structural components, allowing the architecture to connect meaningfully with the environment.

Central Dune Formation

At the heart of the design is a central dune formation that serves both as a landmark and a functional structure. This dune departs from conventional building forms by mimicking the look and feel of a natural sand dune. It changes shape based on the visitor's perspective, which encourages a closer engagement with the landscape. Moreover, the dune offers practical features such as providing shade and a place to view the surroundings, enriching the experience of being in a natural setting.

Shading Walls

Shading walls are strategically placed along the boardwalk to enhance visitor comfort. These walls protect against the sun's heat, allowing people to explore the outdoor space more comfortably throughout the day. By maximizing shade while blending into the environment, the walls contribute to a more inviting atmosphere, making the reserve a pleasant destination for all visitors.

Accessibility and Inclusion

The design carefully considers accessibility, ensuring that the space is inviting for people of all abilities. This attention to inclusivity reflects modern principles in architecture that prioritize equal access. The layout, along with thoughtful modifications, helps create an environment where everyone can engage with the natural beauty of the reserve. It emphasizes a commitment to welcoming diverse groups into outdoor spaces.

Innovative Material Use

One of the notable features involves using Bacillus pasteurii bacteria to create a strong biological cement that binds local sand into usable bricks. This method represents a departure from traditional construction practices by providing an environmentally friendly option. The resulting sand bricks are incorporated throughout the design, notably in the dune and shading walls, which reinforces the connection with the surrounding landscape.

Visitors will also find "infobricks" placed within the structures, providing information about the local ecosystem. These informative elements enhance visitors’ understanding and appreciation of the area. They also integrate naturally with the architecture, adding a layer of educational value to the experience. The combination of design elements reaffirms the spirit of exploration within the Al Wathba Wetland Reserve, as visitors navigate through both the architecture and the diverse natural setting.

`
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.
