The Kurgi Observational Tower is situated in the North Vidzeme Biosphere Reserve in Latvia, designed to provide a unique vantage point while respecting the local landscape. The tower functions as a place for observation, allowing visitors to connect with the natural surroundings. Its design is inspired by the form of a tree trunk, which helps it blend into the environment. The slender shape reduces visual disruption and invites exploration of the area.

Design Concept

The design reflects a strong connection to nature, focusing on harmony and simplicity. The tower features staggered floor plans that decrease in size as you move upward, resembling the rings found in a tree trunk. This configuration creates a dynamic spatial experience. Each upper level offers something different, cultivating an engaging environment for visitors.

Structural Elements

At the heart of the tower is a steel frame that supports all levels and includes a lift shaft. This structure ensures stability and safety while providing unobstructed views of the landscape. The use of vertical timber elements throughout the design reinforces the connection to the surrounding trees, enhancing the user experience with framed openings that draw attention to the scenery outside.

Foundation and Terrain Interaction

The tower is elevated on localized pad foundations, which allows it to sit above the ground and minimizes disturbance to the natural terrain. This thoughtful approach to construction helps preserve the site while reducing the need for heavy machinery during building. The foundation system highlights a commitment to coexistence with nature, making the tower feel less intrusive in its setting.

Lighting and Heating

Interior lighting is integrated through the use of vertically fixed fixtures that blend into the overall design. This choice reduces visual clutter and maintains a calming atmosphere for visitors. For warmth, the upper levels utilize an electrically powered radiant heat source. This approach efficiently provides comfort without taking up valuable space.

Carefully designed viewing platforms allow occupants to enjoy framed vistas of the rolling hills and dense forests. This connection with nature enhances the overall visitor experience, making interaction with the environment a central aspect of the tower’s purpose.

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.
