In the 1830s, a section of Gravel Pit Field was transformed into Ossington Street, extending from the former Uxbridge Road to Moscow Road. Initially named Victoria Grove, it was later renamed Ossington Street in 1837 when it became part of Kensington. It is speculated that the street derived its name from Viscount Ossington.

On the western side, the buildings consisted of two-story terraced cottages with basements, accompanied by a mews located behind them. Victoria Grove Mews retains its original name to this day.

To the south, a number of terraced houses were leased to William Ward, a builder from Marylebone. Ward also erected an inn and five shops, known as nos. 1 to 6 Wellington Terrace, between Victoria Grove and the former Paddington boundary, around 1840.

By 1865, the majority of Bayswater had been developed, leaving only a few spaces for further construction, particularly south of Moscow Road and along the eastern side of Victoria Grove. This area was developed into Palace Court, which features remarkable examples of late Victorian residential architecture in the locality, with its west side backing onto Ossington Street.

Presently, Ossington Street serves as the dividing line between the City of Westminster and the Royal Borough of Kensington and Chelsea. The eastern side falls under the jurisdiction of Westminster, while the western side belongs to Kensington. The River Westbourne flows beneath the street.
