In 1978, the heiress Christina Onassis, who owned a three-bedroom flat in nearby Reeves Mews, flew in to London for a one-day shopping tour, amid considerable press interest.[2] She viewed the house, but was apparently put off by the de Grimston co-founders of The Process Church of The Final Judgment, living in the street, and the press calling their property "Satan's Cave".[2]
In 1991, the house was converted into six flats.[4]
In 2014, it was listed for sale at £45 million, with seven reception rooms, 19 bedrooms, six kitchens and 17 bathrooms".[5][6]
