## Kip Island Auditorium Overview

The Kip Island Auditorium is situated within a strategic coastal context, aimed at serving as a multifunctional facility that enhances community interaction and engagement. The design emphasizes a balance between public amenities and performance spaces, merging indoors and outdoors in a manner that respects the natural surroundings. The architectural intent is to create a robust structure that promotes sustainability while facilitating diverse uses, including restaurants, cafes, conference rooms, and exhibition halls.

### Architectural Form and Integration

The auditorium's design incorporates a series of curved, dome-like forms combined with linear elements, creating a visually striking silhouette that responds to its landscape. The domes serve dual functions; they allow natural light to penetrate the interior while simultaneously enhancing acoustics, which is crucial for performance venues. Landscape integration is a key aspect of the design, featuring landscaped terraces that act as botanical gardens and support biodiversity. Outdoor areas include paths and water features that encourage public engagement and create inviting spaces for community activities.

### Material and Structural Systems

The building predominantly utilizes wood for its cladding, providing warmth and a connection to the natural environment. PTFE membranes are employed for their waterproofing properties, ensuring durability in the coastal climate. Additional materials such as stretched steel cables contribute to the structural integrity, while reinforced concrete forms the foundation and essential structural elements. The incorporation of innovative features, such as photovoltaic surfaces and wind turbines, aligns with the project's commitment to energy efficiency and reduced carbon footprint. Adaptable rooftop gardens equipped with rainwater irrigation systems further emphasize the integration of sustainability within the design framework.

`
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.
