## 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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
