What Petra Ecclestone Would Lose If She Sells $150 Million Mansion

— -- The word on the high-end realty block is that Formula One heiress Petra Ecclestone is ready to sell the nearly 57,000-square-foot Hollywood mansion she purchased from Candy Spelling in 2011.

Ecclestone, 25, called it a “great investment” when she purchased the 7,000-square-foot master suite home for $85 million three years ago. She is now quietly shopping around the home with an asking price of $150 million, Spelling’s original price before the home languished on the real estate market.

“It's definitely worth the money and I think someone will buy it,” Kurt Rappaport, a Los Angeles real estate agent who recently sold the nearby Fleur de Lys mansion for $102 million, told ABC News.

If Ecclestone, whose Italian wedding to businessman James Stunt in 2011 included a performance by the Black Eyed Peas, does sell the Bel Air, Calif., mansion known as the Manor, she will leave behind a reported $25 million renovation that took a fleet of 500 workers just nine weeks to complete.

“I’ve got quite masculine taste. I don’t like a lot of pattern,” Ecclestone told W magazine in a 2012 profile that described the home as having been transformed into, “an old Dynasty-like set to a massive VIP lounge.”

Ecclestone kept the home’s two-lane bowling alley, but turned Spelling’s doll collection room into an in-home spa and a customized 20-seat cinema.

The bowling alley is located in the basement level of the home, along with a bar and pool room all designed to resemble a nightclub, according to W.

In addition to the fun and games, a $150 million sale means Ecclestone would also leave behind the 7,000-square-foot master suite that, as she showed W, includes its own kitchen, living room and his-and-hers bathroom and closets.

Ecclestone’s closet, according to the magazine, features a pair of staircases to reach the second level and two “glass-top center islands.”

When Ecclestone purchased the home in 2011, she described it to ABC News’ Nick Watt as being her second home, since she already owned one of Britain's most expensive homes, a Georgian mansion in Chelsea, valued at an estimated $90 million.

"I wanted to move to L.A. I wanted to have an amazing home. Hopefully in the future I'll be raising a family," she told Watt in July 2011. "My family from London will be coming to visit, so I need loads of space. But it really was a great investment. ... I've got a house in London and I just kind of buy prime real estate that I know hopefully won't go down in value."

Aaron and Candy Spelling spent a reported $45 million building the mansion in the 1980s. In addition to the interior, the 6-acre compound has a pool, tennis court and exquisite gardens, and is one of the largest single-family homes in California.
