Petal-Shaped Viewing Structure Constructed with Locally Sourced Birch and Sustainable Materials

Project in-detail

A petal-shaped observation tower crafted from locally sourced birch and aluminum rises above the North Vidzeme Biosphere Reserve, offering visitors panoramic views while promoting education and cultural appreciation of local agricultural practices.
5 key facts about this project
01
Petal-like upper structure enhances the interaction between the building and its natural surroundings.
02
Louvered facade increases energy efficiency while providing controlled light and ventilation.
03
Construction utilizes locally sourced birch to reduce environmental impact and promote regional materials.
04
Hexagonal plan creates multiple observation points throughout the ascent, enriching visitor experience.
05
Focus on agricultural education, particularly the preservation of an endangered horse breed, integrates local culture.
The Kurgi Tower is an architectural project located in North Vidzeme Biosphere Reserve, Latvia. It serves as an observation tower and educational facility designed to foster a connection between visitors and the natural environment, as well as highlight the agricultural practices of the region, particularly focusing on the preservation of an endangered horse breed.

The structure features a hexagonal plan, which allows for a multi-faceted experience as visitors ascend. Its coalescence with the landscape is achieved through a careful design that integrates varying perspectives of the surrounding biosphere, elevating educational and recreational opportunities.

Unique Architectural Language

The Kurgi Tower differentiates itself through its architectural language, inspired by local rural structures, particularly horse stables and entry portals. This thematic approach roots the design in local tradition while presenting a modern interpretation. Notably, the upper segments of the tower are designed with petal-like forms, suggesting growth and harmony with nature, a unique feature that encourages dialogue about the indigenous flora and fauna.

Sustainable Material Use

A critical aspect of the Kurgi Tower is its commitment to sustainability through material selection. Locally harvested wood, specifically Latvian birch, forms the primary material for the facade, while brushed aluminum accents are employed to create contrast and visual interest. The integration of a louvered facade enhances environmental performance by regulating light and temperature, promoting energy efficiency within the structure. Furthermore, a concrete foundation provides stability, ensuring resilience against the local climate.

The Kurgi Tower stands as an important project that embodies the essence of its geographical context while addressing contemporary architectural challenges. For those interested in a deeper understanding of its architectural plans, sections, designs, and ideas, exploring the detailed project presentation is highly encouraged. This will provide insights into how the Kurgi Tower exemplifies a thoughtful blend of architecture and nature-focused education.
