Montpelier Square is a residential garden square in Knightsbridge, London, administratively in the City of Westminster. The homes were built in the 19th century and are of brick construction partly covered by stucco. All of the buildings facing inwards are listed grade II (the mainstream, initial category) in the heritage listing scheme used in England.
From a point in Plantagenet England until 1955, Kensington's eastern spur was thinner, amounting to Brompton (a forlorn term for a wedge of Knightsbridge to the south).[1] Instead these easterly fields of Kensington Gore reaching north to nearly the Serpentine and going past its hamlet hub to the fence of the Palace (formerly royal manor) then from 1901 to Kensington Church Street) presented the largest exclave within Ossulstone (the Kensington Gore detached part of St Margaret Westminster).[2]
Internally, excluding small porches, the square measures by . Private communal gardens, to centre, measure 0.2ha.[3]
Grade II listing of 44 Montpelier Street, one of two southern approach ways, means that all houses within two-house-fronts of directly facing the square plus those - all classical houses, whether or not internally converted to flats - facing it are listed buildings. 1–17, 17a–43 are listed Grade II on the National Heritage List for England for their architectural merit. No.s 44 to 47, forming the eastern approach way (there is also a fourth approach way which is to the west) are not listed.
Average full houses, on long leases, of the square cost £8.2 million in 2018.[4]
In 2007 the Evening Standard saw the square a strong 'street of success' where 'the capital's corporate powerbrokers choose to make their homes'. The square ranked equally, 36th, as to declared housing of directors of companies with a turnover of more than £10 million.[5]
Helen Cecelia Black visited Mrs. Lovett Cameron at her such home for her book Notable Women Authors of the Day: Biographical sketches and described the rich interior of Cameron's house.[6]
Victor Lownes lived at No. 3 in the 1960s; Christine Keeler attended a party there in 1966 where she was spiked with LSD. Roman Polanski and Stuart Whitman were also guests at the party.[7] The Beatles also went to parties at Lownes's house.[8]
The dancer Michael Flatley sold his house for £7.2 million in 2015.[9]
