## Overview and Concept

Located in Kharkiv, Ukraine, Freedom Square is the focus of an architectural redevelopment project that aims to modernize the public space while preserving its historical significance. This initiative seeks to honor the square's artistic legacy from the 1920s and 1930s by fostering community engagement and improving functionality. The design approach bridges the historic character of Freedom Square with a commitment to sustainability and innovation, reflecting a vision for both continuity and progress.

### Structural Layout and Spatial Interaction

The design integrates a central atrium with several cantilever arcs—Eternal Arc, Infinite Arc, and Reverence Arc—creating dynamic spatial experiences that encourage pedestrian movement and interaction. The arrangement of buildings along radial streets enhances accessibility and visual connectivity across the site, facilitating a flow between diverse public spaces. The arcs are designed for various civic functions, including relaxation, community engagement, and historical reflection. A tunnel also links different zones within the square, ensuring modern amenities align with the site's historical context.

### Materiality and Sustainable Systems

The project focuses on a selection of materials that balance durability and aesthetic quality. Ultra-High Performance Concrete (UHPC) mixed with recycled content is utilized for its sustainability credentials, while robust steel structures support the cantilevered elements. Double-glazed windows are incorporated to improve energy efficiency without compromising the square's architectural heritage.

An advanced HVAC system features Energy Recovery Ventilation (ERV) to optimize air circulation and minimize energy usage. Additionally, solar panels mounted on the roof of the arcs contribute to the facility's renewable energy supply, reinforcing the commitment to sustainable practices. This blend of innovative materials and systems not only enhances energy efficiency but also sets a precedent for future urban developments.
