It is probably named after the Bladindon family who owned land in the area.[2] Blendon Hall was built in 1763, was sold to a local housing developer in 1929 and eventually demolished to make way for suburban housing.[3] Today the area is a middle-class residential district with a small row of shops along the western stretch of Blendon Road.
Blendon borders Bexleyheath to the north and north east, Bexley to the east, Albany Park to the south east, south and south west, Blackfen to the west and Welling to the north west.
