Using a unique hexagonal mesh combined with a steel structure, the flamingo observation tower enhances biodiversity within a wetland while providing visitors multi-level access to birdwatching experiences.
5 key facts about this project
01
The observation tower allows for unobstructed views from multiple levels.
02
The design includes a courtyard for visitor gathering and relaxation.
03
Hexagonal openings connect interior and exterior views dynamically.
04
A lightweight structure minimizes visual heaviness, enhancing landscape integration.
05
Biodiversity efforts aim to attract various wildlife through plant diversity.

The Spire is a flamingo observation tower designed to connect closely with a diverse wetland ecosystem filled with plant and animal life. It provides a platform for visitors, allowing them to observe flamingos and other bird species in their natural habitat. The design focuses on the relationship between people and nature, creating an experience that encourages exploration and understanding of the environment.

Design and Functionality

The tower includes several viewing levels, each offering different perspectives for visitors. This design allows individuals to see wildlife from multiple angles, enhancing their experience. A central courtyard is part of the design, serving as a gathering space where people can relax and take in the surroundings. This feature adds to the overall enjoyment of the site.

Structural Innovation

A prominent characteristic of The Spire is its integrated column that also functions as a viewing platform. This approach moves away from traditional column designs, creating a more open and inviting space. The lower platform encourages visitors to engage closely with the landscape. It also leads toward a bird hide, making the journey through the area thoughtful and accessible for everyone.

Material Considerations

The materials used include steel tubes and a hexagon mesh that is produced with a 3D printer. The steel tubes are made off-site, while the hexagonal mesh is assembled on-site, resulting in a lightweight structure. The design uses a metal mesh floor slab on the ramp to maintain the tower's structural efficiency and visual appeal.

Biodiversity Integration

The Spire focuses on enhancing biodiversity within the wetland. By increasing the variety of plants in the area, the design aims to attract more wildlife. This aspect highlights the importance of creating spaces where nature can thrive alongside human activities.

The hexagonal openings in the structure create interesting views of the surrounding landscape while allowing natural light to enter. This design choice connects visitors with the wetland, making it a vital part of their experience.

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.
