It had been decided in 1873 to separate children from adult lunatics in the Hampstead Asylum and Leavesden Asylum. To this end, the former London Orphan Asylum in Clapton was subsequently rented for 3 years at the end of 1874 as a temporary asylum. Land in Darenth, near Dartford Kent was bought in 1875 and building began on the erection of the new school buildings, capable of housing 500 children. The transfer took place in 1878, vacating the premises in Clapton. Due to heavy demand accomodation for adult lunatics was also included
The asylums are referred to variously as: "Clapton Asylum", "The Metropolitan District Asylum, Clapton", "Clapton and Darenth Asylums" and "Clapton and Darenth Asylums for Imbecile Children"
