Bill Koch's House In Cape Cod Is Listed For $15 Million After He Purchased Rachel 'Bunny' Mellon's Nearby Estate (PHOTOS)

And why he's choosing to move around the corner instead.

Billionaire Bill Koch has put his home on the market for $15 million -- but he's not going too far, according to The Cape Cod Times. The president and CEO of Oxbow Corp. and the brother of fellow petroleum tycoons Charles and David, Koch recently scooped up the most expensive property in the area: a nearby estate belonging to Rachel 'Bunny' Mellon for a mere $19.5 million.

Listing agent Robert Kinlin told The Cape Cod Times that it may take up to 18 months for Koch to unload the house at this price point. But it does have one thing in its favor -- its nautical-inspired design and charm. "It has been left in excellent condition, but it is reminiscent of old Cape Cod," Kinlin said of the property's architecture, adding, "It's timeless."

According to the listing on, the 8,653-square-foot house, originally built in 1929, has nine bedrooms, 12 bathrooms and sits on 1.58 acres of a private island called Oyster Harbors off of Cape Cod. The estate offers views of Nantucket Sound and has a private beach, pool and a deep water dock, perfect for an avid boater, like Koch.

But if you think these digs sound amazing, not surprisingly, Koch's new house sounds pretty remarkable as well. Mellon, the 102-year-old heiress and former owner is a well-known horticulturist (she redesigned the White House's Rose Garden for Jackie Kennedy) who has maintained the gardens on the 26-acre property. Reportedly, Koch plans to restore the grounds to their original glory.
