It is also home to a new development of houses situated on the former site of Warley Hospital (a mental hospital), called Clements Park. The development includes a range of house styles modelled around local themes, such as the former water tower that supplied the local area. It also includes the former hospital chapel that has now been converted to flats.
There was also another prominent mental hospital in Warley for over 150 years, known as Mascalls Park Mental Hospital, although its operations were moved to the site of Goodmayes Hospital in early 2011.
There is a council polling ward by the name Warley, which takes in Great Warley, Little Warley, Childerditch and the Woodman Road/Hartswood area of Brentwood. Traditionally it has been a Liberal Democrat-Conservative marginal, which won brief fame in 2007 after it elected the youngest ever councillor in Britain, at eighteen years of age.
