Sydney’s prestige property market is seeing a surge in “collective sales,” with groups of homeowners joining forces to secure lucrative deals with developers.
In Mosman, one of the city’s most exclusive suburbs, twelve neighbouring homes across three street frontages were quietly acquired by development firm Arissa Group. The off-market purchase, spearheaded by brothers Frank and Joe Scarf, remains confidential in terms of price, though the directors confirmed that reports of an $85 million figure were inaccurate.
The acquisition included six properties on Brierly Street and another six on Rangers Avenue, prized for their prime Mosman address, leafy outlook, and close access to schools, shops, and transport links to North Sydney. What began as a plan to secure six homes eventually expanded to twelve after planning outcomes encouraged a broader vision for the site.
Arissa Group spent months door-knocking to gain owner interest, with negotiations spanning roughly half a year. The site is now earmarked for an eight-storey residential project that could deliver up to 100 apartments. Importantly, the developers have committed to including affordable housing as part of the project, in line with the NSW Government’s Low and Mid-Rise Housing Reforms.
With Mosman’s median house price for a four-bedroom home sitting at $5.5 million, the development could bring a more accessible housing option to the area.
Meanwhile, in Rose Bay, another high-profile deal unfolded. Two neighbouring homes on Old South Head Road were sold together for approximately $15 million. The combined 1100sqm parcel, within walking distance of Rose Bay Town Centre, is zoned for medium-density housing and allows a gross floor area of up to 1650sqm. According to selling agents Zorick Toltsan (RWC Eastern Suburbs) and Graham Berman (Ray White Double Bay), the owners achieved a stronger outcome by selling jointly than they would have individually.
This isn’t the first time collective deals have reshaped Sydney’s affluent suburbs. Earlier this year, Savills facilitated the purchase of six homes on Rangers Avenue for around $60 million, while five Cremorne properties were also amalgamated in a separate transaction.
With property prices in suburbs like Mosman and Cremorne stretching beyond the reach of many families and professionals, grouped land sales are becoming an increasingly popular way for homeowners to maximise value—and for developers to create much-needed housing opportunities.
