Description from record TR 25 NE 59 :
The malthouse dates from the early or mid 19th century and althouth its early ownership is uncertain it was run by one G.Hatcher around 1882.It is now a Listed Building. The building is built in red brick with a slate roof and is two storeys in height with a wing added to the rear, perhaps for storage. Two square-plan kilns with pyramidal roofs, one at each end of the main building(with ground level loading doors in one) seem to have been added later, perhaps to replace an earlier(possibly internal Kiln) and/or to provide barley drying facilities.Alternatively they could date from when the building became an oast in the late 19th or early 20th century.(1-2)
