South Street is a refined and tranquil residential street nestled in the heart of Mayfair, a district within the City of Westminster, London. Running east to west, it connects the grand thoroughfare of Park Lane with the quieter and more intimate Farm Street. This elegant enclave is known for its historic architecture, secluded atmosphere, and reputation as one of London’s most prestigious addresses.
South Street lies in the western reaches of Westminster, between the hustle of Park Lane and the genteel charm of Farm Street. The street sits just north of Curzon Street and parallel to Upper Grosvenor Street, placing it within easy walking distance of Hyde Park and central Mayfair’s high-end shops, clubs, and restaurants.
The ambience is one of understated luxury. Flanked by Georgian and early 20th-century mansion blocks, interspersed with elegant townhouses, South Street exudes a quiet, exclusive character. Traffic is minimal, and much of the street is residential, with gated mews and private front doors giving a village-like feel in the centre of a global city.
South Street was laid out in the 18th century as part of the grand Mayfair estate development, designed to house the upper classes within proximity to Hyde Park and the political heart of the country. The street’s architecture reflects a range of styles, from classic Georgian to Edwardian brickwork, with many properties retaining period features and ornate detailing.
The name “South Street” likely reflects its position on the southern portion of the original Mayfair grid layout. While there is no dramatic historical tale behind the name, it follows a typical London pattern of pragmatic, directional street-naming common in 18th-century developments.
One of South Street’s most famous former residents was Winston Churchill, who lived at 28 South Street as a young man. His time there in the late 19th century is commemorated with a plaque, offering a small historical touchpoint for visitors.
