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:

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.

Deflection Head Details

What Are Deflection Head Details?

Deflection head details are specialized components used in wall and partition systems to accommodate vertical or horizontal movement in a building’s structure.

They are typically placed at the top of walls, allowing the structure to expand, contract, or shift without compromising the wall’s integrity or performance.\

This movement can be caused by various factors, such as dead loads, live loads, thermal expansion, or seismic activity. At KOROK Building Systems, our deflection head solutions are designed to provide the flexibility and stability needed in high-performance wall systems.

Dead and live loads can cause significant deflection in some structures. KOROK® can provide deflection C-track details where deflection loadings are considered.

KOROK deflection head details:

• Maintain Structural Integrity: Designed to allow movement in walls without damaging the structure, these details help prevent cracking or separation in response to building movement.
• Ensure Fire and Acoustic Performance: KOROK deflection heads are rigorously tested to retain fire resistance and acoustic ratings, even with movement, maintaining protection in all conditions.
• Seismic Readiness: In New Zealand, where seismic activity can impact building structures, our deflection head designs are engineered to absorb and adjust to seismic forces, supporting safe and resilient structures.

Whether used in commercial or residential projects, KOROK’s deflection head details meet the highest industry standards, offering a reliable solution for builders, architects, and contractors who prioritize safety, performance, and durability.
