Westbourne is an area west of Paddington in west London. It has a manorial history spanning many centuries, within a more broadly defined Paddington, before shedding its association in the mid-19th century. It is named after the west bourne, West Bourne, or River Westbourne, a Thames tributary which was encased in 19th-century London in the 1850s. The spring-fed stream and associated manor have led to the place names Westbourne Green, Westbourne Park and more narrowly: Westbourne Gardens, Westbourne Grove, Westbourne Park Road, Westbourne Park tube station, Westbourne Studios and the name of a public house. Westbourne forms or resembles an electoral ward of the local authority which is, since 1965, Westminster City Council, and an ecclesiastical parish in the Church of England. Westbourne Conservation Area is a smaller area, designated by the local authority, in Planning Law. Early history The hamlet of Westbourne was a High Middle Ages (mid-medieval) settlement, centred on Westbourne Green. It included a mansion house and a farmhouse. It is recorded as Westeburn in 1222 and as Westborn in 1294. The green is recorded as Westborne Grene in 1548, Washborne Green in 1680 and Wesborn Green in 1754. Modern name and definitions The manorial bounds of Westbourne were kept alive by business names and residents' groups and associations after housing development. A short-lived London Underground station existed from 1866 until 1871, when it was replaced by one nearby, to the east. Until 1992, the station had extra platforms on its north side for the overground Great Western Main Line. To the north and east were extensive railway yards. Excellent transport and ease of access of fashionable commerce such as in Marylebone encouraged many City of London affluent workers and the political class of Westminster to live in the area. More recently, the Westbourne Park bus garage was built, replacing railway yards north-east of the station, across the Western Avenue, London. Use of "Westbourne" unsuffixed by "Park" or "Green", has faded but not passed; it has an electoral and a planning definition. The area resembles and can be defined loosely as Westbourne ward, one of twenty Westminster City Council electoral districts, north of the Westway and around the Great Western Road. Wards are drawn by an independent commission to aim for equality of electorate, instead of containing interrelated housing, to avoid malapportionment. The population at the 2011 Census was 12,759.
