Seabell, one of the earliest homes ever built in Palm Beach, has been listed for sale.
The Pacific Road estate was home to the late former civil engineer Laurie Seaman.
Seaman's grandfather built the sandstone home in 1918 when there were only four other houses on the hill overlooking Palm Beach and Pittwater.
Built with stone quarried on site, the striking three level classic sandstone cottage on 2,070 sqm still features its large sandstone fireplaces, original hardwood floors and beamed ceilings.
There are five bedrooms, a home office and a freestanding artists' studio.
A number of dining terraces capture the views.
The gardens, which featured on Burke's Backyard, have been expanded over the years.
Laurie opened the gardens for groups of senior sand disabled people who couldn't visit parks and reserves.
He would walk them through the meandering paths and over the drawbridge that he installed.
Ray White Palm Beach agent Noel Nicholson has a guide of $5 million for its August 29 auction.
