Now on the market: the Mayfair mansion of Princess Diana’s stepmother Dame Barbara Cartland

If the walls of this Mayfair mansion could talk, they’d definitely have some interesting tales. The five-storey London property was home to Dame Barbara Cartland, a world-famous romance writer who’s probably better known as Princess Diana’s stepmother, and it’s just gone up for sale. 

28 South Street is a six-bedroom property boasting bags of Edwardian features, and it’s tucked between Park Lane and Grosvenor Square. Real estate doesn’t get much more prime than that.  

According to the New York listing, the building has vast amounts of space on the lower and ground floors, meaning the reception rooms can host more than 100 people. Did someone say spacious house party?

What’s more, though the house is most known for belonging to Dame Barbara, it was also the birthplace of former UK Prime Minister Alec Douglas-Home.

The property also features a timber staircase, decorative ceilings and a lavish basement swimming pool, sauna and bar. Take a look at 28 South Street in all its opulent Edwardian glory.

The building’s quintessentially British history (and affiliation with Lady Di) is expected to make it pretty popular with American buyers, so you better snap it up quick to beat the competition. If you’ve got £35 million lying around, that is. You can find out more on the official listing here
