## Overview

Located in Ukraine, the retrofit project addresses ecological and social challenges by transforming existing war-damaged structures into sustainable living spaces. The design process emphasizes a dual focus on structural integrity and community engagement, aiming to create functional environments that confront and rise above the impacts of conflict. Each element of the project contributes to a cohesive identity centered on resilience and sustainable living.

## Materiality and Construction Methods

The project employs a selection of materials chosen for their functional properties and contextual significance, facilitating enhanced performance and the building's longevity. Key materials include magnesium oxychloride for structural walls and floors due to its strength and insulation properties, while textiles and foil are utilized in air distribution to optimize temperature regulation. Glass facades are incorporated to maximize natural light and provide visual connectivity to the surroundings. Cold extrusion profiles are utilized to reinforce the structure and allow for modular construction, while polystyrene enhances thermal efficiency. This carefully curated material palette supports the overall sustainability goals of the project.

### Structural and Environmental Strategies

The design incorporates innovative structural reinforcements through strategically placed support systems that enhance the existing building's stability. This approach ensures the ability to accommodate modifications in living spaces without compromising safety. Additionally, the project features an advanced airflow system, employing textile ceilings to balance indoor climate and promote natural ventilation, thereby minimizing dependence on mechanical HVAC systems.

Social interaction is encouraged through the arrangement of public and semi-public spaces, which include private gardens accessible from living spaces, atriums with water features, and outdoor shelters. These elements foster community engagement and environmental sustainability. A modular approach allows for flexibility in space usage, tailored to resident needs and adaptability to environmental changes. Community involvement is prioritised to ensure that the design meets the functional requirements of its users and promotes shared ownership.

`
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.
