Connecticut's sprawling Copper Beech Farm estate sells for a record-breaking $139 million see inside

• The $138.83 million transaction represents Connecticut's priciest residential real-estate deal.
• The estate once held the record for the country's most expensive home sale at $120 million in 2014.

A 50-acre estate on a private peninsula in Greenwich, Connecticut, just sold for $138.83 million, breaking the previous record for the most-expensive sale in the state.

Copper Beech Farm was listed in February for $150 million. It last sold in 2014 for $120 million which, at the time, was the priciest sale in the country. That national record has since been beat out by financier Ken Griffin's roughly $240 million purchase of a New York City condo in 2019.

The seller of Copper Beech Farm was The Conservation Institute LLC, a Connecticut company that has ties to hedge fund billionaire Ray Dalio, the Wall Street Journal reported.

Sotheby's International Realty's Leslie McElwreath and Joseph Barbieri represented the seller and Stephanie Bo Li of Douglas Elliman represented the buyer. A spokesperson for Sotheby's declined to comment on the identities of the parties.

In addition to the main house and extensive outdoor amenities, the property includes two structures for hosting guests. Take a look around.

Copper Beech Farm, originally called Kincraig, was built in the 1890s for industrialist John Hamilton Gourlie.

It was also formerly owned by the Lauder Greenway family. Harriet Lauder Greenway's father helped Andrew Carnegie found US Steel.

Before its most recent sale, the property traded hands in 2014 for $120 million. The buyer was The Conservation Institute LLC, which is tied to Bridgewater Associates, the hedge fund founded by Ray Dalio.

The estate's buyer was interested in the property's potential. "There was tremendous opportunity for further development to create a family compound," Barbieri told the Wall Street Journal.

And it wouldn't be a luxurious property without a grass tennis court, the same kind of court used in the prestigious Wimbledon tournament.

There's also a three-bedroom gatehouse and a two-bedroom carriage house on the property.
