### Overview
The Ribbon Tree Bird Observation Tower is situated at Pape Park, a site known for its ecological significance and rich avian biodiversity. The project aims to enhance the birdwatching experience while ensuring minimal environmental impact and promoting interaction with the local natural landscape. Through its design, the tower seeks to integrate architecture with ecology, inviting visitors to appreciate both the setting and the wildlife it supports.

### Spatial Configuration
The design features a 50-meter-long path made up of gently ascending ramps that lead to a series of observation platforms. Each platform is positioned at varying heights, allowing for diverse vistas of the park and emphasizing a gradual ascent into nature. This approach encourages a sensory exploration of the environment, inviting users to engage with the park's flora and fauna throughout their journey. The structural design resembles the organic growth of trees, featuring a central core that branches out into four primary supports. This configuration maintains a reduced footprint, minimizing disruption to the surrounding wetlands while maximizing visibility for observers.

### Material Considerations
Materiality is a key element in the observatory's design, reflecting a commitment to sustainability and contextual relevance. Local timber is utilized for the flooring of the platforms and ramps, chosen for its ecological impact and alignment with the area's vernacular architecture. Steel elements provide necessary durability and are treated to resist corrosion in the wetland environment. Additionally, aluminum is incorporated in the central lighting structure, emphasizing both safety and functionality. Collectively, these materials form a cohesive relationship with the surrounding landscape, ensuring that the structure harmonizes with its ecological context rather than imposing upon it.

The tower's inclusive design caters to visitors of all abilities, promoting accessibility while fostering a sense of community connection within nature. Future enhancements, such as the potential integration of solar panels and other eco-friendly technologies, are considered to further align with the project’s sustainable objectives.

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.
