A waterfront property in Woods Hole is on the market, and if the asking price holds, it could be the highest-priced real estate transaction ever on Cape Cod.

The property is going for $25 million. The current record-holder is the 2013 sale of a compound in Osterville for $19.5 million to billionaire Bill Koch.

Architect Michelle Foster designed the house at 187-191 Penzance Road in 1992, and the estate on 9.6 acres features five bedrooms and six baths. The 10,544 square-foot was owned by Wall Street executive and philanthropist James Clark, who died in 2015 at the age of 93. The family has owned the property since the 1950s.

"It is a rare offering that encompasses an iconic main residence, a charming guesthouse, verdant grounds and gardens, a 36-foot swimming pool, and a rugged boathouse with a woodburning fireplace and a deepwater dock—all enveloped by the waters of Great Harbor and Buzzard’s Bay, with Naushon Island and Hadley Harbor in view," according to listing agent Kerrie Marzot.

Clark was known for his generosity and contributed significant sums to the Clark Cancer Center at Falmouth Hospital and the Woods Hole Oceanographic Institute. WHOI's Clark Arctic Research Initiative is named after Clark.

Clark's son, Jamie Clark, who lives in Texas, decided to sell the property. The home is listed with Sotheby's International.
