CASE STUDY

30 Madden Street, Multi-Unit Residential

Located in Auckland’s Wynyard Quarter, 30 Madden represents the latest chapter in one of New Zealand’s largest urban regeneration projects. Developed by Willis Bond and designed by Studio Pacific Architecture, this multi-stage residential development features over 150 apartments, townhouses and duplexes across five buildings.

With sustainability and liveability at its core, 30 Madden achieved a 7-Star Homestar rating and received accolades including a Gold Pin at the 2022 Best Design Awards and an Excellence Award at the 2022 NZ Property Industry Awards. Behind the scenes, KOROK® played a key role in delivering high-performance intertenancy wall systems that supported both the environmental and construction goals of the project.

KOROK’s Contribution

To meet the stringent fire and acoustic performance requirements of multi-residential buildings, KOROK® supplied our 78mm Galv Panels for use in all intertenancy residential walls across the 30 Madden development. In multilevel buildings like apartments, intertenancy walls must achieve excellent fire resistance and sound insulation – while also fitting into tight construction programs. Traditional framed systems often rely on linings that complicate detailing, especially in ceiling plenums. KOROK® Intertenancy Residential (KIR) Wall Systems offer a smarter alternative:

• No ceiling plenum linings required
• Outstanding fire and acoustic performance
• Streamlined design and faster installation
• Less material waste and reduced cost

Our KOROK® 78mm Galv Panels are roll-formed from zinc-coated steel and filled with a proprietary aerated concrete core. Each panel weighs only 10.2 kg per lineal metre, making them a lightweight yet high-performing solution that’s well-suited to modern mid- and high-rise developments like 30 Madden.

A System That Supports Award-Winning Design

With high-end finishing, elevated community spaces, and sustainable features such as stormwater harvesting and native landscaping, 30 Madden stands as a showcase of future-focused urban living. KOROK’s contribution ensured that behind the architectural elegance lies robust fire and acoustic protection – providing peace of mind to residents and long-term performance for the building.

When it comes to passive fire penetrations, KOROK® leads the way with innovative solutions that ensure fire safety without compromising functionality.

At KOROK®, we are committed to providing fire-rated wall systems that prioritize safety, durability, and performance. Our advanced KOROK® panels are specifically designed to allow seamless integration of passive fire penetrations, including service ducting and pipes, while maintaining the structural and fire integrity of the wall.

What Are Passive Fire Penetrations?

Passive fire penetrations are openings or pathways in fire-rated walls or floors that allow services such as plumbing, electrical cables, or ductwork to pass through. These penetrations are essential for building functionality but must be carefully designed to prevent the spread of fire and smoke. KOROK® panels are engineered to make the creation and sealing of these penetrations straightforward and effective, ensuring compliance with strict fire safety standards.

Fire Stopping Guidance Documents

At KOROK®, we understand that ensuring fire safety goes beyond the wall system itself – it’s also about how penetrations and services are detailed. That’s why we’ve collaborated with leading experts in passive fire protection to develop a suite of manuals that provide fully tested, NZBC-compliant solutions for penetrations in KOROK® fire-rated wall systems.

Each manual has been developed in partnership with industry specialists and contains tested configurations, installation guidance, and compliance references, making it easier for designers, engineers, and contractors to select the right firestop solutions.

Our firestop manuals, developed with industry partners, provide tested and NZBC-compliant solutions for service penetrations in KOROK® fire-rated wall systems.

Why Choose KOROK® for Passive Fire Penetrations?

• Easy Formations for Penetrations: KOROK® panels simplify the creation of openings for ducting and plumbing. The lightweight yet robust design makes it easy to form precise and efficient penetrations without compromising fire safety or wall integrity.
• Maintained Wall Integrity: Even with multiple passive fire penetrations, KOROK® panels ensure the overall wall system retains its fire rating. This is crucial for preventing fire and smoke from spreading across compartments in a building.
• Versatile Applications: Whether your project involves commercial spaces, residential apartments, or industrial facilities, KOROK® passive fire penetrations provide a reliable and efficient solution tailored to meet your needs.
• Compliance with Building Codes: KOROK® panels are rigorously tested and meet or exceed New Zealand’s building code requirements for passive fire protection. This gives architects, engineers, and builders confidence in the safety and performance of their projects.

Hobsonville Point: Enhancing Fire and Acoustic Protection with KOROK® Intertenancy Systems

Bringing Kiwi Ingenuity to Hobsonville Point Homes

Here at KOROK®, we’re stoked to have been part of the transformation of the old Hobsonville airbase into a new community. Our innovative KOROK KIR Intertenancy Residential Walls have been key in shaping around 3000 homes across this significant slice of land, including standout spots like the Te Uru Apartments, Walter Merton Road Terraces, Nugget Avenue Terraces, and Buckley A Precinct.

Being part of the Hobsonville Point development really showcases our ability for coming up with smart solutions that tackle the real-world challenges of modern building, especially when it comes to keeping fires at bay and cutting down on noise. Traditional wall setups in flats and hotels usually lean on linings to do this job. But our KIR walls change the game by ditching the need for these linings up top, making the whole building process simpler and slicker.

Smoother Sailing in Building and Design

Our walls have made it quicker and easier to get buildings up at Hobsonville Point. That’s good news for the teams on the ground and means residents can start enjoying their new digs sooner.

Keeping Costs Down

Thanks to the technology behind our KIR panels, we’ve cut down on waste, which means saving some dollars. Those savings can help make other parts of the development even better, making the whole neighbourhood a top spot to live.

Top-Notch Fire and Sound Safety

We’ve put our walls through the wringer to make sure they’re up to scratch for fire safety and noise control. That means folks living in Hobsonville Point can sleep easy, knowing they’ve got solid protection around them.

Built Solid for Extra Peace of Mind

The sturdy design of our walls means homes are not just safe but also built to last. That’s a big plus for anyone calling Hobsonville Point home, offering a secure spot for years to come.

Committed to Excellence in Innovation and Community Building

From the lively look of the Te Uru Apartments to the tidy and thoughtful design of the Walter Merton Road Terraces and the spot-on style of Buckley A Precinct, our KIR panels have been a foundation for success, delivering the goods on fire safety and quiet living. As we look back on our role at Hobsonville Point, we’re chuffed to have delivered solutions that not only tick the boxes for what’s needed in today’s building scene but also help forge strong, safe, and green communities. Our dedication to coming up with better ways to do things will keep us at the forefront of making homes better for Kiwis everywhere.

Cantilevered Eaves

Cantilevered Walls

For External Applications – (Commercial Only)

A Typical Parapet Detail illustrates the structure and support of a parapet wall, commonly cantilevered from the main building structure. This detail focuses on connections that ensure stability and durability, including reinforcement and weatherproofing layers to protect against the elements. Cantilevered parapets require careful attention to load distribution and deflection control, as they extend outward without external bracing, creating a clean, streamlined edge on the building façade.
