## Architectural Design Project in Kharkiv

### Overview of the Project Context
Located in Kharkiv, Ukraine, the reconstruction initiative for the Saltivka district addresses the challenges of urban decay and the impacts of conflict. The primary intent is to enhance the urban fabric through resilient and sustainable design solutions that improve functionality, safety, and visual coherence. This effort involves a comprehensive strategy that integrates infrastructure, public space, and community engagement to facilitate recovery and revitalization.

### Strategic Spatial Planning
The design emphasizes the interplay between new construction and the adaptation of existing structures, focusing on the following elements:
- **Multi-functional Public Spaces:** The introduction of a community center, conference areas, and recreational zones aims to cater to a diverse set of community needs.
- **Integrated Emergency Infrastructure:** The design incorporates underground shelters that serve both as emergency exits and public spaces, increasing overall safety while promoting community interaction.

The layout prioritizes pedestrian access and connectivity, ensuring that navigability and engagement are central to the urban experience. This strategic arrangement is further enhanced by environmental considerations such as tactile landscaping, which seeks to improve outdoor connectivity and support local biodiversity.

### Material and Construction Approach
A commitment to sustainability influences the material selection and construction methods, featuring:
- **Reinforced Concrete:** This material ensures structural integrity while allowing for design flexibility in various building forms.
- **Prefabricated Modules:** These components facilitate energy efficiency and expedite the construction process by minimizing on-site labor requirements.
- **Green Roof Systems:** These roofs not only mitigate stormwater runoff but also contribute to energy generation and ecological resilience.

The adaptation of existing structures within the project preserves historical context while promoting environmentally responsible practices. Strategies such as rooftop energy systems further embody a pragmatic approach toward resource conservation and urban regeneration.

### Innovative Features
Distinctive aspects of the project include:
- **Integration of Security Features:** The inclusion of bomb shelters within residential and communal buildings enhances the design's focus on urban safety in response to contemporary challenges.
- **Provisions for Accessibility:** Public spaces and emergency facilities are systematically designed for ease of access, promoting inclusivity in community planning.
- **Collaboration with Local Stakeholders:** Engagement with the community provides crucial insights, supporting a design that reflects local needs and values.

This design initiative represents a significant advancement in integrating contemporary architectural practices with urgent urban recovery needs, setting a benchmark for addressing similar challenges in other cities facing post-conflict situations.

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.
