The integration of a glazed volume and an earthy coating forms a compelling oasis in the desert, serving as a visitor center that promotes education and interaction with the surrounding wetlands.
5 key facts about this project
01
The design incorporates a central water mirror that cools air for natural ventilation.
02
A Trombe wall structure helps regulate indoor temperature through passive solar heating.
03
Native flora is showcased in an inner courtyard, emphasizing local biodiversity.
04
Earth-toned external coating mimics natural landforms shaped by water.
05
The orientation maximizes airflow, harnessing prevailing winds for enhanced comfort.

The OASIS Al Wathba Visitor Center is located in the Al Wathba wetlands of Abu Dhabi, designed to connect with its natural surroundings. This facility focuses on education and engagement, aiming to raise awareness of the area's diverse ecology. The central idea behind the design is inspired by the concept of mimicry, where the building reflects the characteristics of an oasis, utilizing water as the key organizing element of the structure.

Design Integration

The building consists of two main parts: a glazed volume that houses the primary functions and an outer layer that mimics natural geological formations shaped by water. The glazed portion acts as a Trombe wall, absorbing and storing heat from the sun, which contributes to energy efficiency. The earthy outer coating reduces solar gain and visually blends the structure with the landscape, making it a natural part of the environment.

Spatial Relationships

The design promotes a strong relationship between the building and the surrounding landscape, featuring an inner courtyard filled with native plants. This encourages visitors to interact with the local ecosystem. The layout creates clear visual connections, allowing people inside to experience both enclosed spaces and open views of the outside. A terrace, partially hidden, offers a direct interaction with nature, reinforcing the connection between the built form and the environment.

Climate Response

Bioclimatic principles are central to the design, addressing the specific climate challenges of the region. The orientation of the building is carefully planned to take advantage of natural airflow, utilizing prevailing winds for ventilation. Air moves through a circulation network that cools as it passes over a central water feature, contributing to indoor comfort and supporting a sustainable approach to design.

The OASIS Al Wathba Visitor Center highlights the importance of preserving the ecological balance of the Al Wathba wetlands. The design features thoughtful elements, such as the way the sunlight interacts with the glazed surfaces throughout the day, encouraging visitors to reflect on the relationship between human-made structures and the natural world.

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.
