Cavendish Square

Cavendish Square is a public garden square in Marylebone in the West End of London. It has a double-helix underground commercial car park. Its northern road forms the ends of four streets: Wigmore Street, which runs to Portman Square in the much larger Portman Estate to the west; Harley Street, which runs a similar distance; Chandos Street, which runs for one block; and Cavendish Place, which runs the same. The south side of the square is modern, including the rear façade and accesses to a flagship department store and an office block. On the ground floors facing are Comptoir Libanais, Royal Bank of Scotland and Pret a Manger premises.

Oxford Circus 150m south-east is where two main shopping streets meet. Only the south is broken by a full-width street, Holles Street. which also runs one block only; the north is broken by Dean's Mews in which Nos. 11–13 exist, the office conversion of a nunnery, retaining a chapel in its rear.

Planning permission was granted in April 2020 for a subterranean health and wellbeing development of 280,000 square feet across four storeys below ground level.
