This unusually large rectangular plaque was installed on the gatepost of Aubrey House by the London County Council in 1960. Following complaints from the house's principal owners in 1969 that the presence of the LCC initials on the plaque was encouraging some to view the house as public property, and force their way into the grounds, it was covered over by the Greater London Council with a sign reading 'Aubrey House. Private' by 1972 and remained so for some 30 years. It was formally reinstated into the official London plaque scheme in 2007.
