The Zurich Australian Insurance building at 5 Blue Street, North Sydney is set for major redevelopment, with a proposal to replace the 14-storey commercial tower with a 29-storey mixed-use development containing approximately 400 residential dwellings and upgraded public domain spaces.
Submitted by the NSW Housing Delivery Authority on behalf of Zurich Australian Insurance Properties Pty Ltd, the plan is intended to deliver high-density housing above North Sydney Railway Station, leveraging the site’s centrality and connectivity to respond to the city’s broader housing supply challenges.
The proposed redevelopment would retain and enhance the adjacent Blue Street Plaza, a publicly accessible but privately owned 700m² forecourt space that offers views across Sydney Harbour. The proposal also anticipates coordination with the separate redevelopment of 15 Blue Street, aiming for a consolidated ground-level design outcome to improve pedestrian access and urban amenity in the area surrounding the station.
The 5 Blue Street site lies at the southern fringe of the North Sydney Centre and spans 11,723m². Though the Zurich building has received recent lobby upgrades, it is considered a legacy asset with limited ongoing commercial viability. The proposed redevelopment is intended to act as a catalyst for precinct renewal, complementing the shift in development momentum northwards following the opening of Victoria Cross Metro Station and its associated uplift in planning controls.
The redevelopment is subject to the NSW Government’s State Significant Development assessment pathway and is currently in the Secretary’s Environmental Assessment Requirements (SEARs) stage. It will subsequently proceed to an Environmental Impact Statement, followed by public exhibition, submissions, formal assessment and a final determination.
The site was formerly designated a ‘Special Area’ under the North Sydney Local Environmental Plan due to solar access protections affecting Blue Street Plaza, though this classification was removed in 2018. Height controls continue to apply to the plaza section of the site, which the proponent has acknowledged in planning documentation.
The application claims strategic merit for rezoning on the basis of increased housing supply—including affordable housing—proximity to heavy and metro rail services, and enhancement of the surrounding public domain.
