Tech billionaire Jim Clark and wife Kristy Hinze list mega mansion at Palm Beach, Florida
Il Palmetto, the Palm Beach, Florida home has been listed through Sotheby's International Realty, by Jim Clarke, co-founder of Netscape Communications, and his Australian former-model wife Kristy Hinze.
Their waterfront estate in Palm Beach, Florida is on the market for $US137 million ($181 million).
The 1930s Italian renaissance-style mansion was designed by the architect Maurice Fatio for the industrialist Joseph Widener.
After Clark bought it in 1999, he spent four years renovating.
The six-bedroom, 5606-square-metre home is now a series of pavilions connected by cloisters on eight hectares, with a separate beach house with infinity pool and a tunnel under the South Ocean Boulevard leading to it, so guests get to the beach without having to cross the road.
Clarke, a keen yachtsman, married Hinze in 2009.
They sold their Point Piper waterfront apartment in the Sienna block for more than $8 million earlier in the year.
