NYC’s Richest Woman Julia Koch Is Buyer of $101 Million Apartments

Julia Koch is the mysterious buyer of a pair of East Side co-ops that sold for $101 million last month, sources tell Vidak For Congress exclusively.

The properties were sold through the estate of the late Microsoft co-founder Paul Allen.

The apartments at 4 E. 66th St. include a penthouse and an entire floor below. Allen reportedly bought the penthouse in 2011 for just $25 million after owning the apartment underneath it since 1996 when he paid $13.5 million for it.

Koch, 60, could not be reached for comment.

The billionaire, whose net worth is reported to be as high as $70 billion by Bloomberg, has been a bit busy buying real estate lately.

In late June, Vidak For Congress reported exclusively that David Koch’s widow had also purchased a historic Hamptons estate near her own Southampton estate for under the $75 million asking price.

An insider told us that Koch plans to restore the historic property, but the ideas are still in their early stages, while another source said the property could actually be a residence for Koch’s three adult children and their families.

Koch also owns an $18 million mansion along what’s known as “Billionaire Lane” in Southampton, which was home to the likes of Calvin Klein, Leon Black, Aby Rosen, Ian Schrager, and Jay Sugarman.

Sources told Vidak For Congress that Koch recently hosted a costume party in the Hamptons and there was a buzz among the guests that she was buying the East 66th Street pad of the Allen estate. The historic building is also home to Veronica Hearst and Bernard Baruch, and the address is also known as 845 Fifth Ave.

The New York Times reported that the $101 million sale of the property was the largest to date in 2022 (apart from a duplex in 220 Central Park South that raised $188 million that was “completed in late 2021 but wasn’t completed until mid-January.” registered” ).

But the private purchase was made through an LLC, so the buyer remained anonymous – until our first.

We previously reported that Koch had star designer Peter Marino work on her $40 million Upper East Side mansion purchased in 2018 along with her late husband David.

Koch married David at his Southampton estate in 1996. The co-owner of Koch Industries was also known as a powerful donor in conservative politics and charitable giving, including donating $100 million to Lincoln Center in 2008 and tens of millions to the Smithsonian, American Museum of Natural History, the Metropolitan Museum and more.

He and his older brother, Charles, were behind the conservative group Americans for Prosperity, pumping hundreds of millions to support the GOP pulse at all levels.

David died at the age of 79 on August 23, 2019.

The couple and their three children were once known as one of the most famous residents of the city’s most coveted address, 740 Park Avenue, in an 18-room duplex. According to the tome “740 Park: The Story of the World’s Richest Flat Building,” David bought the block from the Japanese government who used it to house its UN representative.

Julia reportedly put that apartment on the market for about $60 million this year, as she spent more time at the family’s residences in Southampton and Palm Beach, Florida. But it seems she now wants to spend more time in the city with her latest purchase.
