Most expensive home in US listed for $190m

A 200,000 sq m, seafront property in Greenwich, Connecticut, has been put on the market for a cool 190 million dollars.

The price tag has propelled the home to the most expensive home ever publically listed for sale in the US, Stuff.co.nz reported.

The Copper Beech Farm has 12 bedroom French-renaissance-style mansion, 1,200 metres of water frontage on Long Island Sound and two offshore islands.

Grand fireplaces are there on the main house's living, dining and library rooms, and the master bedroom has a marble ensuite and a private sleeping porch.

The house, which was built on 1896, also has a 3-bedroom guest house, a carriage house with a clock tower and a pool house that looks over the 23-metre pool.

Lauder-Greenway family bought the house in 1904 and then the ouse was quietly purchased by timber tycoon John Rudey, 31 years ago, who is now keen to offload the property.
