The estate also features a donkey wheel house which is currently used as an entertainment space as well as stables, an oast house and a Kentish barn.

The 14th century property, originally in possession of the de Ratling family, had additions in the 15th and 17th centuries. During the Cowper family's time at the house, a king post roof was added to the old hall which is one of very few in existence in Kent.
