### Overview

Located within a dynamic urban environment, "CoExistence" aims to redefine modern living by integrating social, environmental, and architectural considerations. The project seeks to enhance the existing urban fabric while prioritizing community needs and sustainability. Through modular adaptability and a community-centric design, the architecture acknowledges the unique cultural identity of its surroundings, exemplified by the incorporation of locally inspired motifs.

### Materiality and Sustainability

The design employs a palette of recycled materials, focusing on repurposed concrete and sustainable wood to minimize environmental impact and enrich the urban landscape. Key materials include:

- **Recycled Concrete**: Sourced from deconstructed buildings, supporting sustainability principles.
- **Sustainable Wood**: Utilized in facades and structural elements, contributing to the durability and aesthetic qualities of the project.
- **Glass**: Incorporated to enhance natural light access and create transparency within the spaces.
- **Metal**: Used in structural components and finishing details, offering both resilience and a contemporary aesthetic.
- **Green Roof Systems**: Designed to improve thermal efficiency and foster local biodiversity.

This thoughtful selection of materials not only reinforces the project’s ecological goals but also promotes a narrative of continuity, resonating with the local context.

### Spatial Strategy and Community Engagement

The spatial organization of "CoExistence" emphasizes mobility and accessibility through the integration of pedestrian pathways and communal gathering spaces. The layout features:

- **Co-Spaces**: Dedicated areas for various communal activities, promoting social interaction among residents and diverse user groups.
- **Park Areas**: Green spaces filled with native plants that enhance biodiversity and provide serene environments for recreation.
- **Emergency Shelters**: Strategically integrated within the design to ensure community safety and resilience.

The building's elevation adapts to environmental factors while thoughtfully landscaped surroundings reinforce the connection to nature, underscoring the importance of green infrastructure in urban development.

`
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.
