Rammed earth walls provide a thermal buffer while framing panoramic views of wetlands, creating an educational visitor center that promotes awareness of local biodiversity.
5 key facts about this project
01
Rammed earth walls enhance thermal performance and connect the structure with its natural setting.
02
The waffle-slab roof allows for natural light and ventilation while mimicking organic forms.
03
Strategic window placements frame views of local wetlands, fostering interaction with nature.
04
Interactive exhibits engage visitors in learning about the reserve’s unique ecosystem.
05
The outdoor terrace serves as a reflective space overlooking the wetlands, enhancing the visitor experience.

Nest is situated within the Al Wathba Reserve, located about thirty minutes from Abu Dhabi's city center. It serves as both a visitor center and an educational facility, focusing on the local ecology, particularly the Greater Flamingos that inhabit the area. The design concept emphasizes a strong connection to the surrounding landscape, creating a space that is both functional and relevant to its natural environment.

Roof Design

The building features an undulating roof made of lightweight waffle slabs. This roof mimics natural forms, offering protection while also connecting visitors to the landscape. The design allows for natural light to enter through clerestory windows, enriching the indoor space and supporting ventilation. This approach helps maintain a comfortable atmosphere inside the building.

Materiality

The walls of the building are constructed from rammed earth, a material that roots the structure in its surroundings. This choice enhances energy efficiency by taking advantage of thermal mass, keeping the interior cool in the heat of the desert. Rammed earth also reflects the traditional building techniques of the region, making the design contextually appropriate.

Interior Layout

Inside, the layout is designed to guide visitors through a series of educational experiences. Interactivity is emphasized, with exhibits that engage guests in learning about the biodiversity of the reserve. A training room is included to prepare staff for sharing essential information about the area's ecological significance. Windows are strategically placed to frame views of the wetlands outside, reinforcing the connection between indoor spaces and nature.

Visitor Experience

The facility includes additional features like a gift shop and a café. These areas enhance the visitor experience by providing spots for relaxation and reflection. The outdoor terrace offers seating with views of the wetlands, encouraging guests to engage with the landscape. The design creates a comfortable and inviting atmosphere, suitable for both learning and leisure.

The building's details, such as the textured rammed earth walls and the clean lines of the roof, create a thoughtful interaction with the natural setting, making the structure feel at home in its environment.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
