A third asylum, Cane Hill Hospital at Coulsdon in the eastern part of the county, followed in 1882.

[3] It was the leading mental hospital for the western half of Surrey, occupying a large site at Knaphill, near Brookwood.

A large two-storey building that was originally the hospital's social club has been converted and registered as a children's day care centre and nursery.
