we learned there's a house that could become the most expensive home on sale in America. It is 56,000 square feet, bigger than the white house, and ABC's nick watt just had to take you inside. Reporter: A six-acre compound, 100-car garage and a two-lane bowling alley. Petra, the formula one hairless, paid candy spelling $85 million for the place just three years ago. But now she's selling. Well, I think she got tired of L.A. Reporter: Word on the streets paved with gold? She's asking $150 million. They call this neighborhood the platinum triangle there's the spelling mansion behind me, a mansion that sold in the spring for $102 million, and over there, the Beverly hills estate where they filmed "The god father," on the market right now for just $135 million. She apparently spent $25 million renovating the 14-bathroom estate, even turning candy spelling's famed doll collection room into a spa. Complete with three hair salon chairs and a mani/pedi station. If it goes for asking price, this will become the most expensive home in America. A title currently held by an east Hampton, New York, estate that sold for $147 million. Boasting this 500-foot lily pond. Here in L.A., the spelling era chintz is now gone. Cozy. I think it's one of the trophy proper tips in L.A. It's definitely worth the money. Reporter: Oh, how the other half of the half of the half of the half of the 1% live. Nick watt, ABC news, los Angeles.
