Elevated pentagonal platforms constructed from durable Siberian Larch offer expansive views of the surrounding habitat, providing a unique environment for bird watching and nature observation.
5 key facts about this project
01
Pentagonal shape enhances structural stability and visual impact.
02
Four tiered observation levels allow for varied viewing angles.
03
Constructed from sustainably sourced Siberian Larch to minimize environmental impact.
04
The design incorporates a spiral staircase for efficient access between levels.
05
Mesh railings ensure safety while maintaining unobstructed views of wildlife.

### Project Overview

The Pape Bird Observation Tower is situated adjacent to a thriving habitat by a body of water, designed specifically to facilitate wildlife observation, particularly birdwatching. The structure serves both as a destination for nature enthusiasts and a noteworthy addition to the surrounding landscape, achieved through a distinctive geometric form and careful consideration of its environmental context.

### Structural Dynamics and User Experience

The tower's design progresses from a cube to an eleven-meter high pentagonal structure, employing a series of rotations and stacking techniques to create a fluid, dynamic form. This architectural strategy results in four distinct levels, each rotated by 30 degrees, which enhances both visual interest and functional utility, allowing for optimal viewing angles. Access is provided by a central spiral staircase, a solution that prioritizes seamless movement while maintaining aesthetic integrity. Two main observation platforms at heights of 5.5 meters and 8.25 meters offer 360-degree views, allowing users to enjoy varied perspectives without obstructing the line of sight for others. The surrounding railings incorporate triangular patterns that echo natural shapes, reinforcing the tower's connection to its ecological context.

### Material Considerations and Environmental Impact

Material selection plays a critical role in the design, with Siberian Larch (Larix Sibirica) identified as the primary material due to its durability and suitability for outdoor environments. Treatments, including water-repellent additives and pressure treatments, enhance the wood's longevity. Glass is strategically employed in observation areas to sustain visual links between users and the surrounding nature, while metal components contribute to structural stability and safety. The foundation of concrete provides a robust base, ensuring the tower's resilience.

The elevated design minimizes ecological impact by allowing flora and fauna to thrive unimpeded. Moreover, the sharp angles and clean lines of the structure reflect the natural formations inherent to the ecosystem, promoting harmony within the setting. The combination of safety features, such as mesh railings, alongside a focus on sustainability through material choice, fosters an inviting environment that emphasizes both architectural innovation and ecological sensitivity.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
