A sprawling amalgamated property spanning more than 3,000 square metres in Rose Bay has been listed for $100 million, joining a wave of large-scale development sites being marketed in the harbourside suburb.
The site combines multiple properties at 1A, 1-3, 5 Conway Avenue and 34 and 34A Carlisle Street, with agents Steven Zoellner and Fred Small from Laing & Simmons Double Bay marketing the opportunity as Rose Bay’s “Ultimate LMR Super Site.”
According to Mr Zoellner, the property’s location and potential Harbour Bridge views from upper levels are expected to attract significant interest from major development companies.
The collection includes a white three-bedroom semi with a sandstone fence at 34A Carlisle Street, sitting on the smallest parcel of 328 square metres, as well as seven apartments at 1-3 Conway Avenue that were built within the past two decades. The site also incorporates a block of four units at 1A Conway and a standalone house at 5 Conway Avenue.
All property owners agreed to sell collectively, recognising the land’s greater value to developers than as individual holdings.
The listing comes as Rose Bay emerges as a focal point for Sydney’s housing reforms. The NSW Government’s Low and Mid-Rise Housing Policy, which came into effect on 28 February 2025, introduced new planning controls to encourage more diverse housing types within 800 metres of town centres and train stations across Greater Sydney and other regions.
Under these reforms, Mr Zoellner said the Conway-Carlisle site could support an apartment building of up to eight storeys, potentially containing 60 to 70 apartments, with a portion designated as affordable housing. Another possibility includes an over-55 development, similar to projects already underway elsewhere in Rose Bay.
The property is situated near Rose Bay Village and the harbour foreshore. Across the road, Mathieson Property is planning an eight-storey building containing 70 apartments.
Rose Bay has seen several major amalgamated sites change hands since the planning reforms took effect. A 5,979-square-metre site combining 12 properties at 41-55 Dover Road and 32-38 Wilberforce Avenue sold for $173 million to aged care provider Waterbrook Retirement Living, whilst a separate amalgamation of six houses and two unit blocks at 20-30 Wilberforce Avenue and 33-37 Dover Road sold for approximately $150 million to a private buyer.
The reforms have sparked debate in the local community. Woollahra Municipal Council has requested a temporary suspension of state government reforms in the town centres of Rose Bay, Double Bay and Edgecliff, citing concerns about local infrastructure and character.
Despite the controversy, the development pipeline continues to grow. More than $200 million worth of development applications have been submitted in Rose Bay in recent months, signalling strong developer confidence in the suburb’s transformation under the new planning framework.
