The use of a perforated concrete shell creates both shading and visual camouflage for a lower observation platform, inviting visitors to engage with the natural setting of Al Wathba Wetland Reserve.
5 key facts about this project
01
The observation tower is oriented along the east-west axis for optimal views of the wetland.
02
A perforated concrete shell provides sun protection and visual camouflage for the platform.
03
The design includes a two-flight asymmetrical staircase to enhance access and engagement.
04
The structure incorporates modular fiber-reinforced polymer panels for the boardwalk.
05
The upper platform features glass railings to ensure unobstructed sightlines of the landscape.

Stairs to the Nature is located in the Al Wathba Wetland Reserve. It aims to provide an observation point that allows visitors to connect with nature. The design brings together the built environment and the natural landscape. It draws inspiration from a "concrete Fata Morgana," a metaphor for the interaction between the lake and desert.

Observation Tower Orientation

The observation tower is aligned along the east-west axis, which enhances sightlines to the Al Wathba lake. This positioning helps visitors easily find their way to the structure while also emphasizing the beauty of the surrounding area. The tower becomes a clear reference point in the landscape.

Staircase Design and Accessibility

The staircase consists of two flights with a slim and asymmetrical form. The wider first flight leads to a lower observation platform that is covered by a perforated concrete shell. This design feature protects against the sun and provides a visual cover for visitors wanting to engage with their surroundings without being seen. The platform is spacious and designed to accommodate all visitors, including those with mobility challenges.

Higher Observation Area

The second flight of stairs leads to a higher observation space that is more secluded. This area invites contemplation and offers a different view of the wetland. The upper platform features glass railings, allowing for uninterrupted sightlines. It encourages observers to immerse themselves in the natural scenery.

Modular Boardwalk Construction

The boardwalk is made from modular fiber-reinforced polymer grid panels. This choice makes construction easier and reduces long-term maintenance. The design features blend function with aesthetics, ensuring that the boardwalk complements the overall character of the project.

The combination of these elements creates a practical design that reflects the landscape's qualities. The structure encourages a deeper appreciation of the Al Wathba Wetland Reserve and promotes interaction with 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.
