The Kurgi Observation Tower is located in the North Vidzeme Biosphere Reserve in Latvia, specifically on Kurgi Farm. The design places importance on being environmentally friendly while encouraging visitor engagement. The tower aims to blend with the natural surroundings while providing a platform for observing the landscape from various angles.

Elevated Structure

The tower starts with a plinthe level that is raised above the ground. This design decision helps protect the existing topography and native vegetation. With this elevation, visitors can enjoy the area's beauty without disturbing it. Open-air spaces are created across the first three levels, featuring seating areas that invite visitors to engage with the outdoor environment.

Observation Platform

A key feature of the tower is the cantilevered observation platform at the top. This platform extends beyond the main body of the structure, allowing for wide, unobstructed views of the biosphere reserve. It acts as a central point for visitors, making it easy to take in the sights. The tower includes stairs and a lift for easy access, ensuring everyone can reach the various levels without difficulty while maintaining a connection to the landscape.

Structural Framework and Materials

The structural design includes pipe columns and wide flange beams that support a metal decking system on each level. The exterior is covered with break metal, which has multiple functions: it provides structural support, acts as a guardrail and windbreak, and serves as a passive solar screen. This clever design helps bring natural light into the tower while allowing views of the outdoors.

Functional and Aesthetic Integration

On the upper floor, there is a conditioned space equipped with a shaker-style wood-burning stove, ensuring comfort in different seasons. Tables and seating arrangements create a welcoming area for visitors. This thoughtful layout merges functionality with a focus on the beautiful natural surroundings. The selected materials—steel, concrete, and glass—are chosen for their durability and low maintenance, aligning with the goal of creating a lasting structure that respects the environment.

The Kurgi Observation Tower promotes a close connection to the natural landscape, enhancing the experience for all who visit. Its design offers both accessibility and a place for reflection in the midst of nature.

`
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.
