Ypsilon Tower, in Northern Latvia near Kurgi Farm, serves as an observation tower that integrates with the natural landscape of the North Vidzeme Biosphere Reserve. The design draws on the vertical forms of local Spruce and Pine forests, creating an engaging experience for visitors while offering expansive views of the surroundings.

Design Concept

The Y-shaped configuration of Ypsilon Tower is both practical and visually appealing. It maximizes the observation area while keeping the structure compact. The main façade is oriented southward, allowing natural light to enhance the space and providing wide views towards both the southwest and southeast. This layout encourages visitors to explore the tower as they ascend, fostering a connection with the landscape at various heights.

Accessibility Features

A key element of Ypsilon Tower’s design is its focus on accessibility. The structure incorporates a lift to ensure that all visitors, regardless of mobility, can enjoy the views from different levels. Curved stairs and plateaus link the various levels, allowing for smooth movement throughout the tower and creating a pleasant journey for those who climb.

Observation Cabin

At the top of Ypsilon Tower sits a cabin designed to connect occupants with the outdoor environment. With glass walls on all sides, it allows natural light to flood the space while providing uninterrupted views of the surrounding area. The cabin features a balcony that extends outward, further deepening the relationship between the interior and the landscape, inviting visitors to experience nature from a new height.

Material Choices

The primary materials selected for Ypsilon Tower emphasize durability and ease of maintenance. A steel frame provides strength while allowing for a slender profile that doesn’t overpower the site. Inside, wooden flooring creates a warm atmosphere, enhancing the visitor experience as they move through the structure and take in the views around them.

As visitors approach the tower, they may notice that the design aims to blend with the environment. Over time, local vegetation may start to grow onto its surfaces, reinforcing the idea of architecture working in harmony with nature. This thoughtful integration creates a space that fosters a deeper connection with the changing landscape of the North Vidzeme Biosphere Reserve.

`
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.
