North Sydney’s long-vacant MLC Building is set to return to use as office space following its recent sale, bringing an end to years of uncertainty over the future of the heritage-listed site. The property changed hands in February for more than A$100 million, with new owner Wentworth Group opting to restore and upgrade the existing structure rather than pursue large-scale redevelopment.

The modernist building on Miller Street has been empty since 2022 and has been at the centre of ongoing disputes over its future. Previous owner Investa had explored multiple redevelopment options, including proposals for a major commercial tower, residential units and an education facility. Many of those plans faced strong opposition due to the building’s heritage significance.

Now, the new owners are focusing on refurbishment. Works are already underway to convert the property into high-quality office space, with potential tenants being shown through the site. The upgraded building is expected to be ready for occupation next year.

Local officials have welcomed the shift back to commercial use. North Sydney Mayor Zoe Baker said bringing the building back into operation would support the broader revitalisation of the CBD, particularly following the opening of the nearby Victoria Cross metro station.

The building itself has a long history. Completed in 1957, it was North Sydney’s first high-rise office tower and later received the NSW Architects Enduring Architecture Prize. Its design has made it an important example of mid-century commercial architecture in Australia.

Debate over the site has reflected a wider tension across Sydney between preserving heritage structures and addressing demand for new housing and development. While the building remains protected, parts of the broader complex have previously been approved for redevelopment, including a plan to replace a secondary wing with a 22-storey tower.

Wentworth Group has indicated it is unlikely to proceed with those approved plans. Instead, the focus will remain on restoring the main structure and reactivating the site within North Sydney’s evolving business district.

Earlier proposals from Investa included a A$500 million office tower, which triggered backlash from architects and conservation groups. The controversy led to the building being added to the State Heritage Register in 2021, briefly removed due to a legal issue, and later reinstated in 2024.

Government planning decisions have previously acknowledged that redevelopment options could impact the building’s heritage value, even while allowing certain modifications to address structural and safety concerns.

With refurbishment now underway, the project marks a shift towards preserving the building’s original purpose while adapting it for modern use, as North Sydney continues to evolve around new transport links and commercial activity.
