Candy Spelling's Mega-Mansion Is World's Most Expensive

April 28, 2010— -- The 56,000-square-foot mansion that Hollywood matriarch Candy Spelling has called home for almost 20 years is now the most expensive home for sale in the world.

Priced at $150 million, the Bel Air, Calif., mansion, known as the Manor, has been on the market for more than a year. Five homes in the world are on the market for $100 million or more, according to Forbes.com.

Spelling, the 64-year-old wife of late television producing legend Aaron Spelling, told CNBS's Jane Wells that she put the mega-mansion on the market because "it's just too big for one person."

In the early 1980s, Aaron and Candy Spelling spent a reported $45 million building their Los Angeles residence. The 6-acre compound has a pool, tennis court and exquisite gardens, and remains one of the largest single-family homes in California.

The house has a kitchen bigger than most restaurants, a breakfast room bigger than most dining rooms, a dining room bigger than most living rooms and a living room bigger than most houses. There's also a gift wrapping room, screening room, game room and a two-lane bowling alley.

When the Spellings were building their Bel Air, Calif., mansion, she said she didn't understand just how big it would be.

"This house started getting bigger and bigger," she told "20/20's" Elizabeth Vargas in an interview last March. "Nobody said, 'Well, look how much square footage you're building.'"

Spelling spoke out to "20/20's" Elizabeth Vargas on her complicated and very public relationship with her daughter, actress Tori Spelling, and her plans to sell the Holmsby Hills estate.

Spelling told Vargas she didn't know how many bathrooms it boasts.

"That's true. I don't want to know," she said with a laugh. "That means I'm buying a lot [of] toilet paper."
