The property, which runs down Rock Road to Porthilly Beach, has four bathrooms, two kitchens, a wine cellar, a gym, and two terraces overlooking the Camel Estuary.
A garden house includes a boat store, carport, its own driveway and three private bathrooms, as well as a kitchen, dining room and living room.
The plot once housed an aging five-bedroom property, which the Ramsays bought for £ 4.4million in 2015 before deciding to destroy the 1920s house and start from scratch.
The Ramsays currently split their time between Rock’s house and their Daymer Bay property two miles away.
Gordon recently shared a photo of his new glass-walled pool. Showing the enviable development, he posed with his grandson Oscar and captioned the snap: “On our way for an evening stroll with @oscarjramsay. ”
It has been a busy month for Gordon and his wife Tana, who welcomed good friends David and Victoria Beckham to Cornwall.
The couple have also joined Cornwall Air Ambulance as new ambassadors for the charity, to help promote the rescue work they do across Cornwall and the Isles of Scilly.
Separately, the Ramsays have listed their property in Fowey for £ 2.75million.
The Fore Street house, which was once Lloyds Bank, was bought by the Ramsays for £ 1.96million in 2017 and then converted into a luxury holiday home overlooking the estuary.
