Spiral Observation Tower Crafted from Cross-Laminated Timber and Steel Framework

Project in-detail

Crafted from cross-laminated timber and supported by a steel framework, the spiral tower provides an elevated platform for birdwatching while seamlessly integrating into its natural landscape.
5 key facts about this project
01
Crafted with cross-laminated timber for superior structural efficiency.
02
Charred wooden shingles provide weather resistance and aesthetic depth.
03
The unique bent A-frame design optimizes elevation and sightlines.
04
Circular platforms enhance visitor engagement and observation variety.
05
Integrated bird-friendly features promote local avian habitation.

### Project Overview
The Pape Bird Observation Tower is situated in a natural landscape, designed to enhance visitor engagement with wildlife and the broader ecosystem. The tower serves a dual purpose: offering a vantage point for bird observation while fostering a deeper connection between visitors and their surroundings. The architectural approach reflects the interplay between a bird's nest and its environment, emphasizing safety and elevation within the design.

### Spatial Dynamics
The design features a winding approach that stimulates the senses and reflects the ascent akin to a bird climbing into its nest. As visitors ascend, they encounter varying perspectives, with each level providing distinct views of the environment. This design strategy supports diverse user experiences as visitors interact with the landscape and observe avian activities. The spiraling arrangement of platforms adds a dynamic quality, allowing the structure to transform with the observer's position.

### Materiality and Sustainability
The construction employs a combination of materials that reinforce the overall conceptual framework. A steel framework constitutes the primary structural element, enabling slender and lightweight construction that integrates well with the environment. Wooden platforms offer tactile warmth and serve as observation points, contrasting with the rigidity of the steel. Glass railings enhance visibility and safety, allowing unobstructed views of the landscape. The selection of materials and construction techniques align with sustainable practices, minimizing ecological impact while promoting local biodiversity through features tailored for bird habitation.
