5 key facts about this project
01
Curvilinear form enhances natural light and visibility throughout the stadium.
02
ETFE roofing reduces structural load while maximizing daylight access.
03
Integrated native vegetation promotes local biodiversity and environmental sustainability.
04
Flexible seating arrangements accommodate a variety of event types and audience sizes.
05
Advanced lighting fixtures serve both functional and aesthetic roles within the design.

## Overview
The multi-purpose stadium is strategically positioned to serve both sporting events and cultural gatherings, embodying a contemporary approach to stadium design. The project aims to foster community engagement and environmental integration through innovative use of form and materials, reflecting modern architectural tendencies.

## Spatial Strategy
The internal layout prioritizes an optimal user experience, featuring an ergonomic, tiered seating configuration that maximizes sightlines to the central arena. Thoughtfully designed circulation spaces facilitate smooth movement during events, while dedicated areas for concessions and restroom facilities enhance convenience. The design accommodates diverse user groups, ensuring accessibility and promoting inclusive community interaction within the stadium.

## Material Selection
The project employs a variety of materials selected for both aesthetic and functional attributes. Key materials include steel for structural integrity, glass for transparency and light penetration, and ETFE for lightweight roofing solutions. Composite materials are utilized within the facade for durability, while concrete provides foundational support. This selection not only contributes to the stadium's distinctive aesthetic but also aligns with principles of thermal efficiency and sustainability, promoting overall operational performance.

`
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.
