Seven years and a comprehensive makeover later, it is expected to fetch more than $3 million in a forthcoming auction.
Now boasting five bedrooms and an infinity pool that looks out over the ocean, the property is attracting interest from local and Sydney buyers.
"They're probably some of the best views that I've seen and are certainly better with your own eyes," said PRD Newcastle and Lake Macquarie's Chasse Ede, who is marketing the property with Nathan Hunter.
"We have sold many properties to the north in Merewether with stunning views however these are some of the best I have seen.
"They easily wrap 180 degrees of the entire coastline uninterrupted.
"The highest sale on record is $4.2 million, there has been several sales above $3 million in recent times including one PRD have just sold in Goulburn Street for $3,515,000 with beach access."
Set on a huge 1719 square metre block, the home is equally as expansive inside with 4.5 metre ceilings and deep alfresco spaces.
It also boasts a spa tub, a pizza oven and has development application approval for a second dwelling at the bottom of the property.
