03

The Flamingo Observation Tower Project is located in the Al Wathba Wetland Reserve in Abu Dhabi, United Arab Emirates. This space functions as both an observation point and a pathway, allowing visitors to connect with the rich wildlife, particularly the migratory greater flamingos that call the area home. The design focuses on harmonizing the building with the natural surroundings, creating an inviting experience that encourages visitors to engage with the environment.

Conceptual Framework

The main idea behind the design involves creating a strong link between visitors and the natural landscape. The concept of "Tunnels to the Sky" is highlighted through circular packing systems, guiding people as they explore the site. This design method aims to foster discovery and a deeper understanding of the local ecology.

Architectural Features

The roof of the observation tower showcases a series of arches and vaults that reflect shapes found in nature. These forms add visual interest while ensuring stability for the structure. Ramps are incorporated into the design, making it easier for visitors of all abilities to navigate and access different viewpoints throughout the tower and the associated boardwalk.

Material Application

Materials play an important role in the design. Cardboard tubes, sourced from the print and fabric industries, are used to provide a sustainable and moisture-resistant option. Acrylic tubes are also incorporated, providing transparency that allows natural light to fill the interiors while contributing to an overall feeling of openness in the space.

Boardwalk Integration

The boardwalk is designed with a modular system, allowing for flexibility in different configurations. Elevating the path minimizes the impact on the landscape and protects the local flora and fauna. Key structural elements, such as pipes used for railings and supports, not only serve a functional purpose but also help unify the overall aesthetic of the design.

In each area, the blend of human-made structures and the natural environment is clearly emphasized, making it possible for visitors to appreciate the ecological importance of the wetland while engaging comfortably with the carefully designed surroundings.

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.
