46 Berkeley Square has been occupied by the private member's club Annabel's since 2018. Annabel's relocated to No. 46 from No. 44 Berkeley Square, where it had been founded by Mark Birley in 1963. In 2007 Birley sold Annabel's and his four other clubs to the businessman Richard Caring. Caring spent £55 million refurbishing No. 46, and Annabel's reopened there in 2018. The club occupies 26,000 sq ft of No. 46 with various restaurants, bars, private dining rooms and a nightclub. A spa is located in the mews house. The interiors were redesigned and decorated by Martin Brudnizki Design Studio.
