5 key facts about this project
01
Constructed using a COB technique that combines local soil, sand, and straw Utilizes dried reedbeds to enhance ecological compatibility Features three distinct platforms for diverse viewing experiences Incorporates an inclusive ramp that serves as an educational pathway Designed to minimize disruption to local wildlife and habitats.

The Tubipora Desert Rose is an observation tower located in Abu Dhabi, designed for the observation of local flamingo populations. It focuses on blending with the natural environment, aiming to reduce any disturbance to wildlife while increasing awareness of ecological issues among visitors. The design uses a smooth, flowing form inspired by the red thumb species found in the area, connecting visually and conceptually with the surrounding landscape.

Design Concept

Three main platforms are incorporated into the design, each offering different views and educational experiences. A ramp leads to these platforms, guiding visitors on a journey through information about the local ecosystem. This ramp provides not only access but also a learning pathway, allowing people to engage with the diverse plant and animal life of Abu Dhabi.

Structure and Materials

The materials selected include dried reedbeds for the boardwalk, aligning with local ecological practices. The main structure is made of a COB technique, which uses a mixture of soil, sand, and straw. This choice reflects a commitment to sustainability. Steel columns support the tower, while pre-cast concrete is used for the foundation to minimize disruption during construction. A stone foundation enhances the overall durability of the structure.

Ecological Integration

Sustainability is central to the design, addressing social, economic, and environmental factors. The tower serves as a community resource that promotes interaction with local ecosystems and encourages educational activities. The careful choice of materials strengthens the tower while ensuring it remains relevant to its natural context.

The observation tower features a curved silhouette that changes with the light throughout the day, drawing attention to the wetlands and the flamingos that inhabit them. This design detail helps create a dynamic visual experience for the visitors, linking them closely to the environment.

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.
