02
The design integrates layers of horticultural fleece, allowing wind to influence its shape and appearance.
03
A shaded stable accommodates visitors arriving on horseback, enhancing accessibility.
04

05
At night, internal illumination creates a soft glow that accentuates the tower's interaction with the landscape.

The Kurgi Observation Tower is located atop the Kurgi estate hill in the North Vidzeme Biosphere Reserve. This structure serves as an observation point, designed to engage visitors with the natural environment. The tower captures the movement of wind and encourages people to connect with the landscape in a meaningful way. The design emphasizes a close relationship with nature, integrating the forces of the outside world into the visitor experience.

Spatial Configuration

The layout of the tower features oval passageways that promote exploration. These pathways blur the lines between inside and outside, creating a sense of continuity with the landscape. As visitors move through the space, they encounter openings that allow the wind to flow through, enhancing the sensory experience. The design invites a natural curiosity, encouraging individuals to wander and discover different perspectives of the surrounding area.

Functionality and Accessibility

The lower level of the tower focuses on accessibility and interaction. It incorporates layers of curtains, allowing the space to adapt to various activities and visitors. A shaded stable nearby provides practical support for those arriving on horseback. Walking paths lead guests to a central washbasin, orienting them within the site and creating a welcoming approach before they begin their ascent.

Materiality and Structural Elements

The construction uses a steel frame that provides solid support while maintaining a lightweight look. Horticultural fleece is used for the curtain layers, which enhances the relationship with the environment. The translucent properties of the fleece allow natural light to play across the interior, creating a visual connection with the changing elements outside. This combination of materials reinforces the tower's role in allowing people to experience nature fully.

Architectural Illumination

At night, the Kurgi Observation Tower becomes even more captivating as its internal lights interact with the fabric layers. This effect produces a soft glow that stands out against the night sky. The illuminated structure serves as a visual beacon, reflecting the natural beauty of the area. This design element not only enhances the tower's presence but also reinforces the intended connection between people and the surrounding landscape, inviting moments of quiet reflection.

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.
