In 1892 the asylum started to accept private patients, the revenue generated by this allowed for further expansion and improvement of the facilities. 1924 saw the facility renamed the City of London Mental Hospital, and after the formation of the National Health Service it was taken over in 1948 became known as Stone House Hospital. Among its most famous patients was the poet and composer Ivor Gurney, who resided there from 1922 until his death in 1937.
In 1998 an assessment by Thames Healthcare pointed to the hospital not being suited to modern healthcare, this signaled the beginning of the end for Stone House and in 2003 West Kent NHS initiated plans for the hospital's closure. November 2007 saw the doors close for good, the site was then sold and has been redeveloped, with the main building being turned into luxury flats and houses built in the grounds.
