The Kurgi Tower is located in Latvia’s Northern Vidzeme Biosphere Reserve, part of UNESCO’s World Network of Biosphere Reserves. It serves as a landmark that connects the biosphere to Kurgi Farm, which focuses on preserving the Latvian Ardennes horse breed. The design draws inspiration from the Fibonacci Sequence, reflecting natural shapes and patterns found in nature while integrating with the surrounding environment.

Concept and Structure

Kurgi Tower features a twisting form that creates an engaging profile, drawing the eye and inviting interaction. The design echoes the image of a horse’s turning head while also symbolizing the letter "K" for Kurgi. This blend of organic shapes enhances the building’s connection to the landscape, establishing a strong visual presence that represents local cultural elements.

Materials and Construction

The tower is constructed with composite wood panels attached to a torsional steel frame. This combination ensures the building's stability while allowing for openness and transparency within the structure. The materials promote extensive sightlines, which are crucial for a fulfilling visitor experience. The use of steel and wood not only provides essential support but also aligns with the natural aesthetics of the surrounding area.

Visitor Experience and Accessibility

Access to Kurgi Tower is designed with visitor needs in mind. The pathway leading to the building accommodates people with disabilities, featuring a gentle slope of 1:20. It is lined with wildflowers and meadow grass, blending naturally with the local landscape. Gardens and stone walls around the tower create spaces for visitors to relax and appreciate nature, enhancing their overall experience.

Interior Design and Function

Inside, the tower consists of several levels, each providing different views of the biosphere. As visitors ascend, they encounter educational exhibits about the Latvian Ardennes breed and the local environment. The journey culminates at an open observation balcony that offers wide-reaching views of the surroundings. The design incorporates solar-powered lighting, which enhances safety and highlights the architectural features both during the day and at night.

At the top of the tower, the Skyroom includes a gas fireplace, adding comfort and warmth. This space allows visitors to sit and take in panoramic vistas of the farm and the natural world around it, making for a peaceful retreat.

`
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.
