The miraGé Flamingo Observation Tower is located in the Al Wathba Wetland Reserve in Abu Dhabi. Designed to function as a space for observing nature, the tower reflects the form of Arabic woven baskets. Its design promotes a strong connection with the natural surroundings and encourages visitors to explore the area's diverse wildlife and ecosystems from different viewpoints.

Structural Design

The foundation of the tower is made up of four concrete piles that are embedded into the earth. This creates a stable base while reducing the impact on the delicate wetland environment. The choice of a four-point support system allows the building to remain lightweight, helping it blend into the landscape rather than dominate it.

A steel structure supports the interior, chosen for its strength and ability to span larger spaces without additional support. This construction allows for open platforms and spiral pathways that guide visitors upward. Each level offers a different perspective, inviting exploration and discovery.

Material Considerations

To ensure durability and ease of maintenance, ecological wood planks are selected for the platforms. This choice aligns with sustainable practices as it provides a natural look while being resilient against the elements. The material choice reflects a commitment to functionality, ensuring that the tower withstands the wear of daily use in a wetland environment.

The outer shape of the tower features an optical illusion that changes based on where a viewer stands. This playful element keeps the experience engaging as visitors move around the structure. Visitors are invited to witness how the sunlight interacts with the form, creating varied appearances throughout the day.

The design includes hexagonal solar panels positioned at the top, which serve to illuminate the tower during the night while offering an interesting visual feature. Accessibility has also been thoughtfully considered, with provisions made for disabled visitors to navigate the space comfortably.

The layered design of the tower allows it to stand out within the landscape while encouraging exploration. As visitors ascend, they are not just observing the wetlands but are also part of the narrative of this unique environment.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
