### Project Overview

Located within a natural context, "The Coral Array" employs a distinctive residential design strategy that merges aesthetic principles with functionality and sustainability. This project prioritizes community engagement and personalized living spaces through a modular design approach, facilitating varied residential needs.

### Conceptual Framework and Spatial Strategy

Rooted in the concepts of organic form and modularity, "The Coral Array" reflects the complexity and interconnectedness found in coral structures. The layout employs circular and octagonal motifs to promote inclusivity and connectivity among homes, thereby fostering a sense of community. The predominance of octagonal forms maximizes spatial efficiency while optimizing natural light and airflow. This flexible layout supports diverse living options, allowing for customization that aligns with individual preferences.

### Materiality and Sustainability Features

The project utilizes a carefully selected range of materials that enhance both functional and aesthetic values. Structural aluminum framing contributes to durability while maintaining a lightweight profile. Glass panels are integrated to provide unobstructed views and maximize daylight, further complemented by masonry elements that improve thermal efficiency. Composite wood finishes add warmth and design appeal, while strategically placed photovoltaic panels underscore a commitment to sustainability through solar energy harnessing. Environmental considerations are integrated into the design, featuring a centralized HVAC system and the use of local materials that promote passive climate control, making the project particularly suited for localized climate conditions.

In addition, outdoor spaces are incorporated throughout, including private gardens and communal areas that encourage interaction among residents and an engagement with nature. The division of shared amenities and landscaped walkways serves to enhance social dynamics within the community.

`
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.
