Dorridge was not considered a district in its own right until 1940. Around the start of the 19th century, much of what is now Knowle Wood Road, (was then Packwood Road) was farmland with just a few dwellings, similarly Avenue Road (which was then Warwick Road) had a handful of dwellings. By the 1930s the main Dorridge Triangle was properly established. Aside from the substantial family homes, there are a significant number of mansions, some of which, such as Parkfield near the park, have now been converted into flats.
