Eve Plumb didn't raise three girls in the home she just sold, but she did star as one.

Plumb, best known for her role as Jan Brady in "The Brady Bunch," was just 11 when she purchased the Malibu, California, property in 1969, the Los Angeles Times reported.

The listing on Realtor.com says the house is relatively small -- just 600 square feet.

It sold for $3.9 million, which, as New York Daily News points out, means Plumb made "a ten-fold return on her investment" since she paid just over $55,000 for the property 47 years ago.

The new owners, who are unknown, have spent millions of dollars on a new house design that's in the works, according to Newsy.

Renderings from the design firm Meis show the new 3,300-square-foot home will have glass walls, a wraparound deck and a retractable moon roof.
