Westbourne Terrace is a street in the Paddington district of the City of Westminster in west London.

In 1868, Cusack Roney wrote in Rambles on Railways, that there were 19 "Westbourne" streets listed in the London Postal Guide.

Architects working in the area included Matthew Wyatt, George Ledwell Taylor, and Thomas Marsh Nelson who was particularly active in Westbourne Terrace in the 1840s on behalf of the builder William Kingdom.

The street has more modern buildings north of Bishop's Bridge Road, including the Enterprise House at numbers 167–169, which is occupied by Network Rail.

According to Nikolaus Pevsner, the architecture of Westbourne Terrace shows the transition from the classical style to the Italianate.

[6] Originally occupied by wealthy merchants, admirals, governors, and statesmen, the terrace has been home to many renowned people.

The exterior of the great majority of the buildings is still intact, though most houses have been converted into flats, and in some instances, hotels or offices.

The original buildings in the terrace are Grade II listed and fall within the Bayswater Conservation Area.

Richard Cobden, an English politician and social reformer best known for his successful fight for repeal of the Corn Laws and his defense of free trade, lived at number 103 from June 1848 to 1856.

Walmsley, Cobden, and Smith were next-door neighbours, living in three adjoining houses at Westbourne Terrace, and hence numbers 101, 103, and 105 Westbourne Terrace came to be known as “Radical Row.”[16] Numbers 121 to 141, later the Dorland Hotel, and now offices of WPP and Ogilvy, is Grade II listed.

It is concrete framed and of six storeys, with facade towards the road and the tracks in the same restrained Art Deco style that Culverhouse employed on the arrival side offices.

The top two floors were a hostel for woman staff, mostly employed in Paddington's refreshment rooms, and Culverhouse provided them with a spacious roof-top terrace.

Brunel House, originally Trinity Lodge, an Italiante stucco villa at number 140 on the southern corner with Orsett Terrace is Grade II listed.
