Inspired by the form of a horse, the observation tower integrates a steel structure and geothermal heating system to create a functional space for viewing the surrounding North Vidzeme Biosphere.
5 key facts about this project
01
The tower's design mimics the shape of a horse, reinforcing its symbolic connection to the site.
02
It utilizes a geothermal heating system for energy efficiency throughout the year.
03
Vertical circulation resembles a spinal cord, enhancing functional movement through the structure.
04
The observatory level features large sliding glass windows for panoramic viewing experiences.
05
Local materials, including steel and treated pine wood, reflect the region's natural resources.

The ZIRGS Observation Tower is situated in Kurgi, a horse breeding farm located in the North Vidzeme Biosphere of Latvia. The design focuses on creating a viewpoint and educational space that interacts with the natural surroundings. It draws on the cultural significance of horses, embodying feelings of grace and freedom, while also allowing visitors to engage with the landscape in a meaningful way.

Symbolism

The name ZIRGS means "horse" in Latvian, bringing a cultural context to the design. The structure's form represents the beauty and movement associated with horses. Features such as flag installations add to its visual appeal and link the tower to historical castles and art museums. This connection fosters a sense of place and identity for the surrounding community and those who visit.

Functionalism

The design incorporates practical elements that enhance visitor experience. Inspired by a horse's neck and head, the tower maintains a strong foundation and a well-organized structure. Vertical circulation, consisting of stairs and an elevator, mimics a spinal cord, ensuring an easy flow between floors. This layout encourages interaction between the interior spaces and the rich natural environment outside.

Spatial Organization

The interior spaces are divided into various levels, each serving a specific purpose. The entry level features areas for exhibitions, while other levels contain a theater, picnic spots, a contemplation zone, and an observatory level. As visitors ascend, the spaces gradually become smaller, leading to a wide observation platform with expansive views of the biosphere. This arrangement enhances the visitor experience, inviting exploration and reflection on the relationship between human activity and nature.

Materials and Environmental Performance

The materials selected for the ZIRGS Observation Tower highlight a commitment to environmental responsibility and local resources. Locally produced steel tubing forms the main structure, providing durability. Treated pine wood is used for interior elements, creating visual coherence. The observatory level features sliding glass windows, allowing for natural ventilation and effective climate control, contributing to overall comfort for users.



The tower’s silhouette, resembling a horse, not only provides a unique visual identity but also creates a connection to the surrounding biosphere. It stands as a thoughtful integration of architecture and nature, enhancing the experience for all who visit.

Competition organisers

The Vancouver Tall Challenge: Building Higher Downtown is an international architecture competition organized by Buildner in collaboration with the City of Vancouver and the University of British Columbia’s School of Architecture and Landscape Architecture (SALA). The competition invites architects, designers, planners, and creative thinkers to explore innovative approaches to tall buildings in Vancouver’s downtown core, focusing on sustainability, livability, urban density, public space, and the city’s strong connection to nature. As Vancouver continues to grow, participants are challenged to rethink how vertical development can enhance urban life and contribute to a more vibrant, inclusive, and resilient city identity.

The competition offers a total prize fund of $15,000 CAD, with winning proposals selected by an international jury of architects, planners, academics, and city-building professionals. Key dates include the final registration deadline on October 29, 2026, submission deadline on November 30, 2026, and winners announcement on January 26, 2027.
