CASE STUDY

Indigo Hotel & Apartments

KOROK is proud to have contributed to one of Auckland’s most distinctive new developments — the Indigo Hotel and Apartments at 51 Albert Street. This iconic project brings together a 4.5-star lifestyle hotel, luxury branded residences, and vibrant food and beverage offerings, all within a uniquely challenging site: a slender 41-storey tower rising from a historic 1912 heritage façade.

Designed by Scott Carver and Dalman Architects and delivered by ICON Construction, the Indigo Hotel and Apartments is a shining example of how careful planning, construction innovation, and respect for heritage can work hand in hand to create a new city landmark.

The Challenge

The development’s highly constrained inner-city site presented several key construction challenges:

• A tight building footprint within a heritage-listed façade.
• Stakeholder sensitivities, with close proximity to neighbouring residents, businesses, and the historic St Patrick’s Cathedral.
• The need for high productivity and precision construction techniques on a vertical build of this scale.

ICON Construction’s advanced project management systems and meticulous construction methodologies ensured these challenges were met head-on, delivering an exceptionally efficient build process.

KOROK’s Solution

To meet the stringent fire and acoustic performance requirements across the tower’s external walls, risers, and duct systems, KOROK supplied our 78mm fire and acoustic rated panel system.

Our panels were selected for their:

• Lightweight nature, critical for high-rise construction.
• Exceptional fire protection performance for vertical service penetrations and separation zones.
• Superior acoustic insulation, ensuring a premium experience for both hotel guests and apartment residents.
• Rapid installation advantages, helping ICON maintain construction momentum within a tight delivery program.

As a pre-finished system, KOROK panels also contributed to reducing on-site finishing work, a key benefit on a project with constrained site logistics and limited laydown space.

Project Highlights

The Indigo Hotel and Apartments development stands out not only for its scale but for its storytelling and celebration of Auckland’s evolving identity.

• The hotel interiors creatively blend industrial elements with heritage materials such as exposed brick, reclaimed timber, and vintage automotive references.
• The modern tower’s guest rooms maintain a refined industrial feel, incorporating subtle local cultural references that connect guests to the heart of the city.
• The podium revitalizes Auckland’s historic entertainment district, contributing new life and energy to a growing cultural hub.

At KOROK, we are proud that our systems play a quiet but vital role in supporting developments like Indigo Hotel and Apartments — delivering life-safety, acoustic comfort, and buildability for landmark projects that help shape the future of our cities.

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

KOROK is proud to have contributed to this landmark residential development, providing solutions that ensure safety, comfort, and efficiency. Our fire and acoustic wall systems continue to set the benchmark for high-performance construction in New Zealand’s premium apartment projects.

KOROK supplied all fire and acoustic wall systems for the project, including:

• Lift Shafts, Risers, and Ducts
• Intertenancy Apartment Walls

Our systems were chosen to enhance fire safety, acoustic insulation, and construction efficiency in this high-end residential development.

KOROK® for Lift Shafts, Risers, and Ducts

KOROK® panels provided an efficient and robust solution for the lift shafts, risers, and ducts at Catalina Bay, offering multiple advantages:

• Single-side installation: Eliminates the need for scaffolding inside shafts, accelerating the build process.
• Pre-weather installation: Our panels can be installed before the building is fully enclosed, preventing water ingress through open shafts and risers.
• Superior fire and acoustic performance: Ensuring compliance with New Zealand’s strict building codes for safety and comfort.

KOROK® for Intertenancy Apartment Walls

Each apartment in Catalina Bay was designed for privacy and luxury. KOROK® intertenancy walls played a crucial role in achieving this by delivering:

• Proven fire-rated protection and acoustic insulation, ensuring a safe and peaceful living environment.
• Solid wall construction, enhancing security and long-term durability.
• Faster installation times, reducing project timelines and labor costs.

BNZ Place: A Testament to Innovation and Sustainability

After nearly four years of design and construction, BNZ Place at 1 Whitmore Street in Wellington is officially open. This 12-storey, 17,000m² building, a collaborative effort between Studio Pacific Architecture and Jasmax, epitomizes practical and purposeful workplace design, combining sustainability, wellbeing, and functionality.

Seismic Resilience and Safety

BNZ Place is one of the most seismically resilient buildings in New Zealand, featuring base isolation to protect against significant structural damage during earthquakes. Raised on a plinth to minimize flood risks and supported by piles extending 60 meters below ground, the building exceeds seismic strength requirements with an NBS rating above 180%.

Innovative Features and Sustainability

Targeting a 5 Green Star As-Built rating, BNZ Place incorporates high-performance solar control glass, energy-efficient systems, and a structural steel diagrid. Efficient floorplates, a double-height entry lobby, inter-floor stairs, and a rooftop courtyard contribute to its state-of-the-art design.

KOROK’s Contribution

KOROK played a crucial role in the construction of BNZ Place by supplying fire and acoustic walls for lift shafts, risers, and ducts. KOROK panels offer significant advantages over traditional construction, as they can be installed from one side only, eliminating the need for scaffolding inside shafts and reducing construction time and costs. Additionally, KOROK panels can be installed before the structure is watertight, preventing water ingress through open shafts.

A Collaborative Effort

The project involved collaboration with various stakeholders, including Newcrest LP, the developer behind the building. CEO Dan Huggins emphasized BNZ’s commitment to Wellington and its future. “BNZ Place reflects our commitment to the city and our vision for the future. We are thrilled to share this vibrant and innovative space with our customers, colleagues, and the people of Wellington,” he said.
