60 King William Street

60 King William Street transforms a strategically important CBD site into a 15-level PCA A-Grade mixed-use destination. Approximately 40,000 m² of premium office space is supported by retail, dining and hospitality uses along Kings Lane, creating a new connection between King William Street and James Place.

A sky lobby, rooftop terrace, business hub, wellness centre and end-of-trip facilities provide a workplace designed around daily experience and long-term value.

The retained Sands & MacDougall façade was central to the project’s identity and one of its most demanding delivery challenges. Its restoration required underpinning, steel bracing, coordinated dismantling and careful sequencing alongside the new tower works. RCP incorporated the heritage requirements, consent conditions, design reviews and façade activities into the project programme, allowing the historic fabric to be protected as construction progressed.

The tightly bounded location created significant access, staging and stakeholder challenges. RCP established an integrated delivery programme that brought together logistics, design compliance, construction sequencing and impact mitigation. This gave the team a coordinated pathway through the works while maintaining focus on programme, budget and neighbouring city activity.

By integrating tenant requirements and commissioning milestones into the wider programme, RCP supported an orderly transition from construction to occupation.

The project set ambitious objectives for an all-electric, net-zero emissions building. RCP translated these objectives into practical programme and coordination requirements across design, procurement, construction and commissioning. The completed building achieved 6 Star Green Star, 5 Star NABERS Energy and Waste ratings, and WELL Platinum certification, and operates using 100 per cent renewable energy.
