Crafted from glulam and straw bales, the observation tower's petal-like structure seamlessly integrates with the wetland ecosystem, providing visitors with an elevated platform for immersive birdwatching experiences.
5 key facts about this project
01
Crafted from locally sourced glulam and straw bales for enhanced sustainability.
02
Petal-like structural design allows for multiple observation platforms with varying sightlines.
03
Central steel core enables flexibility in the tower's outer shell while maintaining stability.
04
Natural ventilation integrated into the design promotes energy efficiency and comfort.
05
Strategically positioned to minimize disturbance to local wildlife during birdwatching activities.

## Project Overview
The bird observation tower, named "SEED," is located in Pape Nature Park in southwestern Latvia, an area notable for its diverse migratory bird population, with over 200 species recorded. The design of the tower aims to enhance the birdwatching experience, allowing visitors to observe wildlife closely while maintaining a respectful distance from their natural habitats. This structure serves as a significant addition to the park, promoting environmental engagement and interaction.

## Architectural Form and User Experience
The tower's architectural composition consists of a modular design with petal-like sections that rise upwards, which not only creates a visually engaging silhouette but also facilitates optimal viewing for birdwatchers. The top platform, mezzanine level, and connecting footbridge offer multiple vantage points for exploring the wetlands. These various configurations encourage visitors to discover the surrounding environment, with an emphasis on exploration and unobtrusive interaction with nature.

### Material Selection and Sustainability
The project incorporates a thoughtful selection of materials that align with the ecological values of the park. Primary materials include straw bales for insulation, glulam timber for structural support, steel brackets for integrity, and glass composites to maximize natural light and provide clear views. This material palette not only emphasizes sustainability but also connects the structure visually and environmentally to its surroundings. By using local and carbon-neutral materials, the design minimizes ecological footprints while enhancing the overall aesthetic coherence of the tower with the natural landscape.

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.
