### Overview

The design for Freedom Square aims to revitalize an essential urban area in [Geographic Location] by integrating themes of memory, sustainability, and public accessibility. This project seeks to create a multifunctional space that enhances community connectivity while addressing historical context and environmental challenges. The design employs innovative architectural strategies to reflect upon shared narratives and foster a sense of belonging among users.

### Environmental and Historical Integration

The project introduces adaptive water features and green landscapes that respond to local climate conditions, capturing rainwater and promoting biodiversity. Structures referred to as Water Flowers, along with solar panel installations, serve both aesthetic and functional purposes, emphasizing sustainability. Historical elements from the war-damaged administrative building are preserved, with approximately 70% of the original volume retained. This approach honors the site’s past while facilitating contemporary use, allowing visitors to engage with the space's rich narratives.

### User-Centric Design and Material Selection

The layout prioritizes pedestrian mobility and encourages cycling through the integration of new pathways while also utilizing recycled materials from war debris, linking the design to its history. A diverse material palette, including reinforced concrete for structural integrity, geotextile for drainage management, and the incorporation of existing war rubble, reflects both sustainability and historical relevance. Community-centric spaces such as social cafes and urban gardens are designed to enhance social interactions, creating a dynamic environment conducive to various activities and fostering community engagement.

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.
