The rammed earth structure, characterized by its diagonal openings that create a visual connection to the surrounding wetland, serves as an observation space to engage visitors with the natural environment.
5 key facts about this project
01
The building features a diagonal opening that aligns with celestial events, marking the winter solstice.
02
Rammed earth construction creates strong thermal mass, ensuring energy efficiency.
03
Vertical layers of columns provide diverse observation experiences through varying viewpoints.
04
Interior ramps facilitate smooth transitions between indoor and outdoor environments.
05
Bamboo elements introduce a natural texture, highlighting local sustainability efforts.

The setting is the Al Wathba Wetland Reserve in Abu Dhabi, where an innovative observation building takes shape. Functioning as a space for visitors to engage with the landscape, the design is rooted in a concept of balance that links the natural world with human creativity. Its architectural form and layout encourage exploration and interaction, drawing people into a unique experience of the wetlands.

Design Concept

The design focuses on harmony and balance, inspired by the ideas of John Ruskin. The building has a distinct shape that widens as it rises, featuring a diagonal opening that runs vertically along its facade. This design not only marks important celestial events, such as the winter solstice, but also serves as a modern reflection of a solar calendar, tying the structure to the rhythms of nature.

Spatial Organization

Inside, the layout promotes easy movement between outdoor and indoor areas, allowing visitors to connect with the wetlands. A series of ramps guide people through different spaces, creating a flow that is both engaging and intuitive. The design offers a mix of wide, open areas and more intimate nooks, giving visitors varied experiences as they explore the structure and its surroundings.

Construction Details

The exterior is built using rammed earth, a method that creates strong and durable walls. This material links the building to the earth, enhancing energy efficiency while maintaining a natural aesthetic. Openings in the walls frame views of the outside, allowing light and air to participate in the interior while fostering a visual relationship with the wetlands.

Interior Elements

The central core of the building supports circulation routes, incorporating ramps and bridges for ease of movement. Vertical columns define the space and connect to the surrounding plants, reinforcing the link between the structure and its environment. The use of bamboo for flooring adds a layer of texture, highlighting an emphasis on sustainability and local resources.

Light filters through a series of carefully designed openings, casting patterns and shadows within the space. This interplay of light and structure enriches the atmosphere, drawing visitors deeper into the tranquil experience of the wetlands.

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.
