## Overview
Located in Pape National Park, Latvia, the Pape Bird Observation Tower serves as a facility for birdwatching and wildlife observation while emphasizing minimal environmental impact and community engagement. The design integrates with the natural landscape to foster an interactive experience for visitors while respecting the surrounding ecosystem.

## Spatial Strategy
The architectural layout consists of a central spiral staircase, representing the trunk of a tree, which connects multiple viewing platforms that mimic the crown of a tree. This design encourages an elevated experience of the natural environment, providing 360-degree views of the park. The ground floor incorporates accessible pathways that lead to the tower, ensuring a smooth transition for all visitors. The open rooftop area enables unobstructed wildlife observation, allowing users to engage with the habitat directly.

## Material Selection
The tower employs a range of sustainable materials that balance functionality with environmental consciousness. An exposed wood structure enhances aesthetic appeal while offering nesting spaces for local birds. Cedar shake panels provide a durable, cost-effective solution that integrates with the surroundings, while plywood sheathing and recycled rubber tiles contribute to structural integrity and sustainability. Steel support elements ensure safety and stability throughout the design. This careful selection of materials not only strengthens the structure but also reinforces the commitment to ecological sensitivity.

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.
