West Halkin Street is a short but distinguished street located in the heart of Belgravia, within the City of Westminster, central London. It extends westward from the grand Belgrave Square to connect with Lowndes Street, serving as a key link between these two elegant corners of the capital. The street is situated opposite Halkin Street—hence its name—with the two roads framing the western and eastern edges of Belgrave Square, respectively.
West Halkin Street runs in a roughly east–west direction, beginning at the northwest corner of Belgrave Square and ending at its junction with Lowndes Street, just south of Motcomb Street. It measures approximately 280 metres (about 920 feet) in length. Vehicular traffic is generally one-way westbound, moving away from Belgrave Square, though road signage should be checked as traffic regulations can change over time.
The street forms part of the early 19th-century layout of Belgravia, which was developed primarily by Thomas Cubitt under the patronage of the Grosvenor family, headed by the Duke of Westminster. Much of the area’s street plan was laid out during the 1820s and 1830s as part of a grand vision to transform former marshland into one of London’s most prestigious residential quarters.
West Halkin Street derives its name from Halkyn, a village in Flintshire, North Wales, where the Grosvenor family held ancestral estates. The spelling was anglicised to "Halkin," and the “West” prefix distinguishes it from the adjacent Halkin Street to the east. The pronunciation of "Halkin" is HAWL-kin, rendered in the International Phonetic Alphabet as /ˈhɔːlkɪn/.
West Halkin Street is quintessentially Belgravia—elegant, understated, and highly exclusive. Its architectural style is consistent with the surrounding area, featuring white stucco-fronted terraces, Neoclassical motifs, and ornate wrought-iron balconies. The atmosphere is quiet and residential, characterised by leafy surroundings, minimal commercial presence, and proximity to embassies and private clubs.
The buildings along the street are largely converted into luxurious flats, private residences, and a few discreet offices. Many homes feature five or more storeys, with original 19th-century façades restored to high standards. There is also an air of discreet affluence, reinforced by private security and high-end car services.
