A landmark Double Bay site is set to hit the market, representing the largest single apartment block ever offered for sale in one line. At 2,757 sqm, this landmark amalgamation of 61 individual lots is poised to reshape Sydney’s most coveted harbourside enclave.
With a price guide over $150 million, the site at 41 William Street is Zoned R3 Medium Density Residential, and benefits from significant uplift under the Low & Mid-Rise Housing Policy, unlocking development potential that few sites in the eastern suburbs can rival.
For sale exclusively through Matt Pontey and Miron Solomons of Cushman & Wakefield with strategic adviser Theo Triant of IREON, the site’s northern aspect promises panoramic views over Double Bay, adding a premium layer to any future project. The site also has the unique benefit of frontage to both the renowned streetscape and picturesque village cul-de-sac of Transvaal Avenue and the stunning treelined harbour facing William Street.
“This is a generational opportunity,” said Matt Pontey of Cushman & Wakefield. “We expect interest from major institutional developers, offshore capital, and high-net-worth syndicates looking to secure a foothold in one of Sydney’s most prestigious postcodes. The buyer profile will be sophisticated and strategic; those who understand the rarity of scale in this location.”
Double Bay has undergone a decade-long transformation, evolving into a lifestyle precinct defined by luxury retail, fine dining, and vibrant village charm. The site’s position at the end of Transvaal Avenue offers dual street access and immediate proximity to the suburb’s best boutiques and restaurants. Connectivity is seamless, with Double Bay Wharf, Edgecliff Station, and major bus routes all within walking distance.
“The location is unbeatable,” Miron Solomons of Cushman & Wakefield adds. “This is the ultimate super lot, the highlight site of the year. It’s the ultimate piece in Double Bay’s evolution, and its development potential is immense.”
