Palm Beach's priciest townhouse trophy home listing's mystery sale

Palm Beach's recent priciest listing has been sold.

It was the Ocean Road townhouse style project of Hardie Grant chairman John Gerahty and wife Patricia.

It was listed with high hopes despite not having the land size of its near record setters.

The Manly Daily speculate the sale price was "around $20 million".

With a handy six car spaces, the Gerahty's home sits on 965 square metres which was part of the Deaton family's Tropique property before it was subdivided and sold off.

One of the parcels went to Sydney Swans chairman and investment banker Andrew Pridham.

The Gerahty's had the four level home was completed just last month by Cadence and Co.

The no-expense spared build was designed to make the most of its north-facing position, with views to the Barrenjoey Lighthouse. 

The home has six bedrooms, a media room and separate guest quarters. 

Christie's International agent Ken Jacobs calls it the pinnacle of Palm Beach.

Jacobs says the natural beauty of Palm Beach and the lack of apartment developments have ensured continued appeal.

A $20 million sale would not be the highest Palm Beach since in 2016 Gretel Packer secured the family bungalow on its well-shaded 4000 square metre beachfront reserve holding in a transfer with a notional $24 million value.

It was 1981 when her father, the late media tycoon Kerry Packer broke through the beachside suburb's million-dollar threshold with his $1 million purchase of the Ocean Road holding from the MacCormick family, who had paid 12,000 pounds in 1952.

The $24 million figure ranked as Palm Beach's priciest as the prior high was the $22 million paid nearby by car dealer Laurie Sutton in 2012 for the trophy home, Kalua.
