### Project Overview

The Baltic Independence Memorial in Riga is an architectural homage to the Baltic Way, a peaceful demonstration in 1989 where citizens from the Baltic states formed a human chain to assert their solidarity for independence. Positioned along the Daugava River, the memorial aims to reflect the historical significance of the event while fostering a sense of community and remembrance within the capital city of Latvia. The design integrates elements of memory and place to enhance the connection between the past and present.

### Material Selection and Sustainability

Careful attention has been given to material selection, emphasizing both aesthetic qualities and sustainable practices. Key materials employed include biodynamic concrete, which minimizes environmental impact; locally sourced stone, promoting regional identity; and natural wood, selected for its low emissions and warmth. The design also incorporates low-emission insulating units to improve energy efficiency without compromising the architectural clarity. Glass features are utilized in various components, allowing natural light to travel throughout the site and inviting interaction with the surrounding environment. The incorporation of landscaping materials such as grass and water features establishes a serene public space conducive to reflection and gatherings.

### Architectural Elements and User Engagement

The memorial is characterized by modular pillars and concrete cores that evoke a sense of unity through their vertical arrangement, symbolizing the interconnectedness of individuals during the Baltic Way. Glass boxes provide transparency and allow visitors to experience exhibitions while engaging with the external landscape. The design's dynamic layout features a meandering path that guides visitors through diverse experiences, blending open spaces with green areas. Additionally, the incorporation of public amenities such as cafes, bookstores, and adaptive exhibition spaces encourages ongoing community interaction. The memorial's strategic orientation and connections to nearby urban infrastructures position it as a central hub of activity within Riga.

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.
