### Project Overview

Located in an urban setting, the Octagon Tower embodies modern architectural principles through its innovative octagonal form. This design enhances functional capacity by facilitating vertical stacking, a critical feature for maximizing land use in densely populated areas. The intent is to create adaptable residential solutions that respond to varying urban landscapes and density requirements.

### Spatial Configuration and Modularity

The Octagon Tower utilizes a modular approach, allowing for five distinct blocks to be stacked vertically, with each block containing six floors. This configuration not only promotes unity within the structure but also caters to diverse functional needs across different urban environments. The inherent design encourages vertical expansion, optimizing limited land resources while creating an efficient living framework.

### Material Formulation and Sustainability

The building predominantly employs concrete for structural integrity, ensuring durability and facilitating height. Glass is used extensively in the facade to maximize natural light, enhancing the living experience and offering expansive views. Aluminum accents provide a lightweight, maintenance-friendly option for detailing and window framing. Together, these materials support sustainability objectives by contributing to energy-efficient design and reducing the overall carbon footprint of the structure.

### Design and Community Integration

The distinctive octagonal shape is reflected in both the silhouette and architectural details, with systematically placed windows that foster light penetration and exterior views. Surrounding the tower, landscaped areas with greenspaces, walking paths, and trees integrate the building with its natural environment, promoting resident well-being and outdoor engagement. The floor plans are carefully organized to balance community interaction with privacy, featuring various configurations that align with the building's octagonal layout while incorporating communal spaces to encourage socialization.

The modular and stackable design sets the Octagon Tower apart, providing flexibility to address site-specific demands and zoning requirements, all while contrasting with the surrounding cuboidal structures to create a dynamic urban presence.

`
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.
