Subscribers only
A circular observation tower built from cross-laminated timber offers unobstructed views and enhanced accessibility, inviting visitors to explore the rich biodiversity of the Al Wathba Wetland Reserve.
5 key facts about this project
01
A circular form enhances stability and integrates with the wetland's organic shapes.
02
The design incorporates cross-laminated timber for sustainability and lightness.
03
All viewing decks are accessible through a carefully designed ramp system.
04
The tower's roof provides shade, addressing the climate of the region.
05
Strategically positioned for optimal views of migratory bird habitats.

The Freedom Tower is located in the Al Wathba Wetland Reserve in Abu Dhabi, recognized as the first protected area in the Emirate as well as a Wetland of International Importance under the Ramsar Convention. The tower serves as an observation point that allows visitors to engage with the wetlands' unique ecology. Designed to enhance the experience of observing diverse wildlife, the overall concept focuses on integrating the structure with the natural landscape in a thoughtful and respectful manner.

Structural Composition

The design features two main systems: the CORE and the SHELL. The CORE consists of wood plank floors and vertical columns that provide a solid foundation for the tower. This structure plays a crucial role in maintaining the overall stability, allowing the spaces within the tower to be arranged in a way that supports ease of movement.



Curvilinear Façade

The SHELL functions as a load-bearing façade, constructed from cross-laminated timber (CLT) units. Such a choice is practical, as CLT is known for its strength-to-weight ratio, which is important for the tower's circular design. This curvilinear form not only adds to the building's aesthetic qualities but also responds to the natural shapes typically found in the wetland, further blending the architecture with its surroundings.



Accessibility Features

Accessibility is a focal point in the design of the Freedom Tower. A ramp system has been integrated to ensure that all visitors, including those with mobility challenges, can reach each viewing deck. This element highlights a commitment to inclusivity, allowing everyone to enjoy the views and experience the wetland more fully. The ramp leads visitors on a journey upward through the tower, enhancing their interaction with the environment.



Visitor Experience

The tower is equipped with a roof covered in fabric cloth, which provides shade for visitors. This detail is particularly important given the region's climate. It allows guests to spend more time exploring the space comfortably. The combination of structural form and practical features creates an environment that encourages visitors to appreciate the Al Wathba Wetland's natural beauty and biodiversity. Each design element contributes to a sense of harmony with the landscape, underscoring the importance of environmental consciousness in today’s architecture.

`
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.
