Spelling Mansion in Holmby Hills, LA, has been placed on sale for $150 million by British heiress and socialite, Petra Stunt (née Ecclestone).

While her billionaire father, Formula 1 chief Bernie Ecclestone, has been making headlines with a high-profile bribery charge, Stunt has proved herself as budding real estate tycoon.

The 25-year-old is selling the expansive Châteauesque home for $65 million more than she paid just three years ago in 2011. Stunt shelled out $85 million to acquire the mansion from Candy Spelling, widow of Charlie’s Angels producer Aaron Spelling.

Along with her husband, entrepreneur James Stunt, Petra employed interior designer Gavin Brodin to overhaul the 56,500-square foot property, which sits in a 4.7-acre estate in the exclusive Holmby Hills neighbourhood.

The home was known to include 14 bedrooms while owned by the Spellings, including the “Prince Charles Suite”, named after a visit from His Royal Highness Charles, Prince of Wales.

Spelling Mansion is believed to be the most expensive off-market listing in California, and is likely to be unrivalled in the whole of the US, Forbes has reported.

If the mansion fetches its asking price, it will set the record for the most expensive home ever sold in the USA, besting the sale of a Hamptons estate that was bought for $147 million earlier this year.

Forbes also reported that former owner Candy Spelling attempted to sell for $150 million before settling for $65 million in 2011.
