Countess Raine Spencer, Stepmother of Princess Diana, Formerly Held This £8.5M Mayfair Residence

The late Countess Raine Spencer, a British socialite and the stepmother of Princess Diana, once owned this 5th-floor London apartment now on the market for £8.5 million—or roughly $10.5 million USD. Located in picturesque Mayfair, the 2,145-square-foot residence is a timeless investment overlooking London’s No.1 garden square and has a unique tie to royal history for buyers to explore as well.

Spencer was married to Princess Diana’s father from 1976 until his passing in 1992, her second out of three marriages. Fifteen-year-old Diana and her siblings called their stepmother ‘Acid Raine’ but later in life the Countess and Diana’s relationship warmed, according to the BBC.

But, this apartment came into the socialite’s life far before she became a Spencer. Back in 1948 when Raine Spencer wed her first husband, who was heir to the Dartmouth Earldom, they gained this 47 Grosvenor Square apartment along with a Mayfair townhouse. The lady of the house mainly used the residence as her political headquarters when she became Westminster City Councillor in 1955. Later when she married Earl John Spencer, she persuaded him to buy a first-floor flat across the street at 48 Grosvenor Square. She moved London addresses quite a bit after her second husband’s death in 1992, but seemingly kept a Mayfair residence throughout her life.

The spacious London haven still has great bones today but is currently available as a blank canvas. It offers two bedroom suites, which both include an ensuite bathroom and dressing room. The living area boasts four windows overlooking the beloved neighborhood. Award

“With its iconic address and garden square views, this Mayfair apartment at 47 Grosvenor Square provides a discerning buyer with a unique opportunity to buy a blank canvas shell unit and refurbish and modernize the property to create a beautiful new residence,” says Peter Wetherell, the founder & executive chairman of Wetherell, which holds the listing exclusively.
