### Project Overview
The project, titled "In Defiance," is positioned within the Norman Foster Foundation Kharkiv Housing Challenge in Kharkiv, Ukraine. This initiative aims to address the urgent housing crisis exacerbated by ongoing socio-political challenges, focusing on adaptive reuse and innovative design to promote community recovery and resilience. The design reflects the principles of Ukrainian vernacular architecture while responding to the infrastructural needs of the city.

### Architectural Composition
The arrangement of housing blocks fosters a sense of community by enabling connections between residents. The design features modular structures that provide flexibility in unit configurations while rising above the landscape. The combination of concrete panels and wooden elements not only ensures durability but also offers visual diversity throughout the housing complex.

### Material Selection and Sustainability
Material choices are made with consideration for structural integrity, durability, and environmental impact. Key structural materials include reinforced concrete and prefabricated panels, which facilitate efficient assembly. Finishing materials, such as insulated wood panels and metal elements, have been incorporated to enhance aesthetic appeal and safety. The landscape design features metal canopies and green spaces that encourage communal interaction and environmental stability, reinforcing the project's commitment to sustainability through local material use and passive design principles.

The project also integrates bomb shelters within its underground structures, addressing security needs in the context of current geopolitical realities, while promoting adaptable living spaces that can evolve with residents' changing lifestyles.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
