This neighbourhood, stretches from the Bayswater area up to Little Venice by Regent’s Canal. The railway lines emanating from Paddington cut through the area, as does the Westway, with only three bridges crossing the area to link it to the northern part of the postcode sector. The area is comprised of purpose-built apartment blocks, dating from the interwar period, in art deco style, as well as post-war council housing south of Bishop’s Bridge Road and north of the railway lines. The south is more upmarket than the north, which has more modest council housing, though Westbourne Park is the largest green space in the postcode sector. There are also green spaces along Regent’s Canal, where the architecture again shifts to grand Regency-era white stucco terraces, with the area being an exceptionally beautiful part of the canal system. There is a large Waitrose near Porchester Square, on Bishop’s Bridge Road, but other than that retail is confined to a few convenience and corner stores.

Westbourne Park and Royal Oak were built-up even prior to the advent of the railways, with development creeping in from central London, though the northern parts of the postcode sector were only really developed afterwards. The area had declined by the middle of the 20th century, with a notorious slum landlord named Peter Rachman targeting West Indian immigrants, who often found it difficult to find accommodation, exploiting this fact. Westminster council later acquired many of these run-down houses and either rehabilitated or replaced them.

Alexander Herzen lived on 1 Orsett Terrace from 1860–1863. He was known as the father of Russian socialism. He grew up and studied in Russia but wrote most of his political works, for which he is most famous for, in London, founding the Free Russian Press, and was well-acquainted with revolutionaries such as Bakunin and Marx.

The area is relatively close to central London, though the railway lines and Westway do obstruct freeflow traffic to the northern parts of the postcode sector, with residents having to cross one of the three bridges from the underground station. In addition, the Hammersmith and City line as well as Circle line on this part of the railway does not have as high a frequency as other tube lines, and occasionally close for maintenance works.

The Hammersmith and City line as well as the Circle line are part of the Four Lines Modernisation which will be finished in 2023, by which time the rail capacity on said lines would have been boosted, in addition to greater reliability. The initiatives include new trains (already delivered), new track and drainage as well as new signalling systems, curing much of the issues faced by the current lines. Users are already reaping the benefits of the upgrades. Since September 2021, journey times between Hammersmith, Stepney Green and Monument have improved by approximately 10%, which has even Transport for London (TfL) the opportunity to increase train frequency on the lines from 27 trains an hour to 28 trains an hour during the busiest times.
