By 1900 Bayswater was thought to end at Westbourne Grove, leaving the district to the north, whose status had fallen, without a general name.A short-lived London Underground station existed from 1866 until 1871, when it was replaced by one nearby, to the east.

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.

Following Hill's departure, the mansion was demolished and replaced by the current gardened houses of Westbourne Park Villas.

Westbourne Farm was centred where the Westway, Harrow Road and Paddington Arm, a canal, converge; in 1815–17 home to actress Sarah Siddons and her daughter.
