The Kent and Sussex Hospital was built on the site of a mansion called Great Culverden House, designed by Decimus Burton.

[2] The hospital building was designed by Cecil Burns, a local architect, and opened in 1934.

The original building was surrounded by lawns on three sides, but the hospital expanded upwards and outwards over the decades.

Services were then transferred from the Kent and Sussex Hospital, which closed on 21 September 2011.

[3] Planning permission was granted to redevelop the hospital site for a mix of housing, offices and a school in December 2012.
