90 Devonport Road

Pushing Boundaries with KOROK

At KOROK, we’re proud to have contributed to 90 Devonport Road—a pioneering project that now holds the title of New Zealand’s largest mass timber office building. Designed by Warren and Mahoney and developed by Willis Bond in partnership with Tauranga City Council, this landmark project redefines what’s possible for sustainable commercial construction in Aotearoa.

As part of the build, 78mm KOROK® fire and acoustic rated panels were specified and installed for external wall applications, contributing to the project’s high-performance envelope while supporting the mass timber structure with lightweight, resilient protection. Installed by Tika Interiors Limited, our panels were chosen for their proven reliability, fast installation time, and ability to support sustainable outcomes without compromising safety or acoustic control.

Sustainability at Scale

The goal was ambitious—a 100% reduction in embodied carbon, with a design targeting a 6 Star Green Star rating (the highest possible), alongside NABERSNZ and WELL Building Standard benchmarks. The result? A building that not only showcases natural beauty through its exposed timber columns and warm finishes, but one that’s genuinely future-ready.

By prioritising timber and selecting high-performance materials like KOROK®, the project team avoided designing in unnecessary complexity or carbon-intensive solutions. This thoughtful approach resulted in a cost-neutral, repeatable commercial model that leads the charge for the next generation of green buildings in New Zealand.

Building for People and Performance

Built by LT McGuinness, this 10,400sqm building now brings together the entire Tauranga City Council administration team under one roof for the first time since 2014. The space fosters collaboration, connection, and a shared commitment to a sustainable future.

“We wanted to push the boundaries to design a wholly sustainable, future-focused workplace which maximises the use of natural materials such as the exposed timber columns which celebrate the uniqueness of the building.”
— Anne Tolley, Chair of the Commission

KOROK’s Role

KOROK’s lightweight fire and acoustic rated wall systems have been engineered to complement mass timber construction by reducing structural loads, supporting acoustic separation, and accelerating installation programs. On a project of this size and vision, our 78mm panels provided the performance needed without compromising the environmental goals or design integrity.

As advocates for sustainable innovation in construction, we are proud to see our systems play a role in delivering landmark projects like 90 Devonport Road. It’s another example of how the KOROK system supports smarter, safer, and more sustainable buildings.

KOROK’s Role in the Project

To ensure the durability, safety, and acoustic integrity of this unique venue, 78mm KOROK panels were selected as the core external wall system solution. KOROK’s fire-rated and acoustic-rated panels played a crucial role in maintaining the building’s aesthetic while offering high-performance protection against fire, noise, and external weather conditions.

Key Features of KOROK External Wall Systems in Glasshouse Morningside

Fire-Rated & Weatherproof Protection

Glasshouse Morningside required external walls that met stringent fire safety requirements while also standing up to New Zealand’s diverse weather conditions. KOROK External Wall Systems provided a high-performing, fire-resistant solution that ensured both occupant safety and long-term durability.

Lightweight & Cost-Effective Installation

With no need for engineered slabs, KOROK’s lightweight panel system significantly reduced material costs and installation time. This efficiency enabled the construction team to maintain the project timeline without sacrificing quality or structural integrity.

Seamless Acoustic Performance

As a venue designed for events and gatherings, controlling sound was a crucial consideration. KOROK’s acoustic-rated panels ensured effective sound insulation, preventing noise disruptions and enhancing the intimate atmosphere of the space.

Durability Without Additional Cladding

Designed specifically for high-wind zones and exposed external applications, KOROK’s panels eliminated the need for extra cladding, reducing maintenance costs while maintaining a sleek architectural finish that complemented the venue’s glass-wall aesthetic.

Conclusion

The Glasshouse Morningside stands as a testament to the versatility and performance of KOROK External Wall Systems. By providing a lightweight, fire-resistant, and acoustically efficient solution, KOROK played an integral role in shaping this iconic Auckland venue. Our systems continue to set the standard for modern construction, offering architects and builders a practical yet high-performing solution for external wall applications.

Catalina Bay Apartments

KOROK® Fire and Acoustic Wall Systems at Catalina Bay Apartments

KOROK Building Systems played a key role in the construction of the Catalina Bay Apartments in Auckland, supplying our high-performance fire and acoustic wall systems. This 13-level waterfront development, built by LT McGuinness for client Willis Bond, consists of 73 luxury apartments across two towers and nine townhouses on a concrete podium. Designed by Architectus, the project integrates sustainability, history, and high-end living, offering panoramic views of Waitemata Harbour.

A Landmark Development with a Strong Foundation

The Catalina Bay Apartments were built on a historically significant site, once home to a Royal New Zealand Air Force base. The design of the development pays homage to this heritage while providing modern, high-quality residences.

Despite construction challenges such as extreme weather events and pandemic-related delays, the project was successfully completed in July 2024, thanks to the collaborative efforts of the client, consultants, and contractors. More than 2,200 workers contributed to this impressive 28-month build.

KOROK® – Setting the Standard in Fire and Acoustic Protection
