Spiral Observation Structure Crafted From Laminated Timber and Reinforced Concrete Emphasizing Ecological Design

Project in-detail

Constructed with a spiraling form of laminated timber and reinforced concrete, the observation tower integrates seamlessly into the North Vahti Wildlife Reserve, offering an immersive experience for wildlife observation while prioritizing ecological sensitivity.
5 key facts about this project
01
Constructed using locally sourced laminated timber, enhancing sustainability.
02
Features a spiraling form that encourages an engaging ascent experience.
03
Observation deck walls are primarily glass, providing uninterrupted views.
04
Integrates discreet lighting designed to minimize ecological disruption.
05
Maintains a height below surrounding trees for visual harmony with the landscape.
The Kurgi Observation Tower is located within the North Vahti Wildlife Reserve in Estonia. The project serves as an observation point for visitors to engage with the surrounding natural environment while providing a structured and immersive experience in wildlife observation. The tower's design emphasizes a harmonious relationship between the built environment and nature, reflecting principles of sustainability and user-centered design.

One of the defining features of the Kurgi Observation Tower is its spiraling form. This architectural choice not only serves aesthetic purposes but also facilitates a logical flow for visitors ascending to the observation deck. The design allows for varied perspectives of the landscape, transforming the journey up the tower into an exploratory experience. The integration of a well-defined path encourages interaction with nature, while the spiral also serves as a metaphor for natural cycles and movement.

The materials utilized in the project are selected for their environmental compatibility and aesthetic qualities. Reinforced concrete provides the structural foundation of the tower, ensuring stability. Laminated timber is used for the flooring and upper sections, bringing warmth to the interior environment. Glass walls at the observation deck enhance visibility and create a sense of openness, while steel supports provide the necessary framework to uphold the complex structure. The use of locally sourced slate for roofing not only contributes to the building's durability but also helps it blend into the surrounding topography.

Sustainability is a key component in the architectural approach to the Kurgi Observation Tower. The design minimizes ecological disruption, presenting a structure that is slightly lower than the surrounding treetops. This sensitivity to height ensures that the tower remains integrated into its environment, allowing for unobstructed views while maintaining a low ecological footprint. Furthermore, special attention has been given to external lighting, which is designed to limit its impact on local wildlife, particularly nocturnal species.

The Kurgi Observation Tower is characterized by its unique blending of natural inspiration with functionality. It serves not only as a structure for observation but also as a catalyst for environmental appreciation and education. The thoughtful integration of materials, structural forms, and user interaction set this project apart from similar architectural endeavors.
