First look: Zurich targets North Sydney office conversion with 148-unit proposal above Metro station

One of North Sydney's best-known commercial buildings could become hundreds of new homes, with insurance giant Zurich Australia lodging a State Significant Development Application (SSDA) to transform 5 Blue Street into a mixed-use residential development above North Sydney Station.

Rather than demolishing the existing building and starting again, Zurich is proposing an adaptive reuse project that would convert the landmark office building into a 15-level residential development delivering 62 apartments, 86 affordable co-living dwellings, activated retail and significant upgrades to the Blue Street Plaza.

The proposal reflects a growing trend of commercial property owners repositioning ageing office assets into residential housing as Sydney grapples with housing supply shortages and changing workplace demand.

Located directly above North Sydney Metro and train station, the 3,051 sqm site occupies one of the most strategically positioned parcels of land on Sydney's Lower North Shore.

Designed by fjcstudio, the proposal seeks to retain and adapt much of the existing structure while creating a contemporary residential address that better connects with the public domain surrounding North Sydney Station.

The application proposes two basement levels, ground floor retail, affordable co-living accommodation across the podium levels, and apartments above, while preserving and enhancing the publicly accessible Blue Street Plaza.

Rather than pursuing maximum apartment numbers, Zurich has opted for a housing mix heavily weighted towards larger owner-occupier residences.

The proposal includes 62 build-to-sell apartments comprising 12 one-bedroom, 19 two-bedroom, 29 three-bedroom apartments and two premium penthouses. It also incorporates 86 affordable co-living dwellings, which would be managed in perpetuity by a Community Housing Provider.

That balance between traditional apartments and affordable housing reflects the NSW Government's push to increase housing diversity around major transport infrastructure.

The proposal has been lodged concurrently with a rezoning application, with Zurich arguing the site is ideally positioned to support additional housing given its immediate proximity to public transport, employment and services.

"The proposal aims to respond to the housing challenges facing Sydney through the delivery of diverse housing types in a highly accessible location," the design report by fjcstudio states. It also seeks to improve pedestrian amenity through upgrades to Blue Street Plaza while creating a high-performing residential building that responds to the surrounding context.

Rather than replacing the commercial building, fjcstudio has developed a design that works with the existing structural framework above the rail corridor, an approach that significantly reduces demolition while allowing the site to be repositioned as a mixed-use residential precinct.

The existing structural constraints have informed much of the building's design, including its relationship with Blue Street and surrounding public spaces.

The building has been designed as a slender tower rising above a clearly defined podium, with vertically expressed façades intended to reduce the perceived bulk while reinforcing North Sydney's emerging skyline.

According to fjcstudio, the architectural language responds directly to the surrounding commercial towers while maintaining a finer grain expression more closely aligned with the neighbouring Lavender Bay streetscape.

The tower incorporates articulated façade elements, landscaped podium edges and recessed upper levels to soften its appearance and improve pedestrian amenity below.

A significant component of the proposal is the revitalisation of Blue Street Plaza.

The existing public space has long served as one of the primary pedestrian connections between North Sydney Station, Greenwood Plaza and Blue Street, yet its role is expected to become even more important following the opening of Sydney Metro.

Zurich's proposal seeks to strengthen that role by improving landscaping, introducing new retail frontages, enhancing pedestrian permeability and creating more active edges throughout the day and evening.

Ground floor retail would wrap the plaza, while separate residential and co-living entries have been designed to improve wayfinding without reducing street activation.

Landscape design has been integrated throughout the podium and public realm, softening what is currently one of the most heavily urbanised parts of North Sydney.

fjcstudio has carefully oriented apartments towards Sydney Harbour and the CBD while using privacy blades and articulated façades to minimise overlooking between neighbouring buildings.

Large framed openings along the western elevation maximise harbour outlooks, while the eastern apartments have been angled towards the south-east to improve privacy from neighbouring development.

The project forms part of the continuing transformation of North Sydney from a predominantly commercial CBD into a genuine mixed-use city centre.

Since the completion of Victoria Cross Metro Station, developers have increasingly shifted their attention towards residential projects capable of leveraging the area's unparalleled transport connectivity.

FiveX recently lodged plans for a 61-storey, 490-apartment tower that would become one of the tallest residential buildings in North Sydney if approved.

Aqualand continues to expand its Lower North Shore presence following the completion of AURA on Walker Street and its recent St Leonards and Roseville proposals.

Developers are also progressing projects throughout Walker Street, Miller Street and the Victoria Cross precinct as demand for well-located owner-occupier apartments continues to strengthen.
