## Overview

The Ark is situated in Adelaide, South Australia, and represents a novel approach to urban design that emphasizes community engagement and cultural connectivity. Drawing inspiration from the city's identities as the "City of Churches" and the "City of Music," the design aims to serve as a versatile hub for local artists, festivals, and civic activities. The project balances material selection, environmental interaction, and accessibility, seeking to integrate diverse activities that enhance public life.

## Spatial Configuration

The master plan outlines a multi-layered layout that caters to a variety of functions, each designed to foster interaction and inclusivity. The ground floor features a large performance space tailored for festivals and public gatherings, complemented by a reception area and café, which create a welcoming environment. Above, the first floor consists of galleries and seminar rooms dedicated to artistic expression and educational activities, while the second floor accommodates additional exhibition space and a theater. The design facilitates fluid movement between levels and encourages adaptability, with open voids and landscaped areas incorporated to enhance user experience.

## Material Selection

Material choices for The Ark reflect its commitment to functionality and openness. Concrete provides structural durability, while glass promotes transparency and visual connectivity between indoor and outdoor environments. The integration of steel in the framework supports both aesthetics and structural integrity, while wood accents in the interior add warmth and a natural feel. Acoustic panels are employed in performance areas to optimize sound quality. The selected materials collectively support the project's ethos of community focus and sustainability, enhancing the relationship between the built environment and its users.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
