Halkin Street is a short but significant street located in the prestigious Belgravia district of central London. It runs in a gentle arc from Grosvenor Place to Grosvenor Crescent, and though modest in length—measuring approximately 165 metres (541 feet)—it is steeped in heritage and marked by a refined, diplomatic character. Headfort Place and Montrose Place connect to Halkin Street with T-junctions.
Halkin Street begins at Grosvenor Place, directly opposite the grand entrances to Hyde Park and Buckingham Palace Gardens, and curves gently westward to meet Grosvenor Crescent. The street operates as a one-way road, with vehicular traffic permitted to enter from Grosvenor Place and exit left-only onto Grosvenor Crescent. This restriction helps maintain the calm, residential tone of the area despite its proximity to major roads.
Halkin Street was developed in the early 19th century during the grand construction phase of Belgravia, a neighbourhood built on the Grosvenor Estate by the 1st Marquess of Westminster. The development reflected the era’s emphasis on elegant urban planning and neoclassical architecture, much of which still characterises the street today.
The name "Halkin" is derived from the Halkyn Castle estate in Flintshire, Wales, one of the ancestral seats of the Grosvenor family. The name is historically spelled Halkyn but was adapted to the more anglicised "Halkin" for the street name. It is pronounced "HAWL-kin", with the International Phonetic Alphabet spelling being /ˈhɔːlkɪn/.
Halkin Street is known for its understated opulence and discreet atmosphere. The buildings lining the street are predominantly white stucco-fronted townhouses, many of which are now occupied by foreign embassies, luxury residences, and boutique hotels. The overall ambience is one of quiet formality, with meticulously maintained facades and mature trees creating a leafy, refined streetscape.
As of May 2025, real estate on Halkin Street remains among the most exclusive and expensive in London. Townhouses and apartments range in size from approximately 1,500 to 6,000 square feet (139 to 557 square metres), depending on configuration. Prices for properties on the street typically fall between £4 million and £18 million, reflecting the street’s diplomatic presence and Belgravia’s overall prestige.
To put this in context, average property prices in Belgravia as a whole hover around £2,500 to £3,000 per square foot, which is more than double the average London figure of approximately £1,200 per square foot.1

Halkin Street was once considered as a possible diplomatic quarter in the mid-20th century due to its quiet location and proximity to government offices in Whitehall. Today, the street retains that international character, hosting diplomatic residences and foreign delegations while maintaining a serene atmosphere unusual for its central London location.
