Description from record TQ 55 NW 99:
This specialist hospital was built on high ground outside central Sevenoaks in 1901-2, replacing earlier converted premises nearby (institution was founded in 1872). The architect of the new hospital was Thomas Graham Jackson, brother of the founder, Miss Emily Jackson. He designed a half-butterfly plan building, comprising a central three-storey administration block flanked by south-facing, angled, single-storey ward wings. The wings originally had covered verandas for use in fine weather. The hospital closed and was partially destroyed by fire in c.1990.(1)
