Porritt Place in Dallington Red Zone – Named after Arthur Espie Porritt (1900- 1994). Porritt was an athlete and an Olympic Games administrator in 1960. In a group of streets named after athletes. Named in 1960.
A small amount of information from the library website. There is a Wikipedia page for Arthur Porritt. I found out that the streets in this area that were named after athletes were possibly built on land that was part of Merry Estate. Merry Estate was the preferred site for the 1974 Commonwealth Games but obviously QE II was chosen for the games. Note the streets were built and named before the Commonwealth Games.
Papers Past had ads in 1961 for houses that were being built by International Homes. There was an article in 1971 about the streets being named after athletes. A few deaths on Papers Past but not much else.
Street view from 2007 shows typical 1960s houses. The street is now in the red zone and no longer has any houses.
