Description

Old Westmill Farmhouse is a house dating from the early 17th century, with a brick casing and an east wing added in the 18th century, which is said to have been renovated in 1735. The building features a timber frame that has largely been replaced with red brick and has steep old red tiled roofs. It is a large two-storey house with attics and a cellar, facing south onto a cobbled yard. The house has two short end wings, with the eastern wing being full height and the western wing having one and a half storeys with a half-hipped roof.

The main house includes four flush box sash windows with 6/6 panes on the first floor, two box dormers on the roof slope, and triple-sash windows on the ground floor. There is a central entrance with two moulded stone steps and a doorcase featuring a dentilled triangular pediment. The eastern gable has a chimney, there is a rear-wall chimney on the western part, and an internal gable chimney for the parlour extension on the east.

The western wing serves as a 17th-century kitchen, constructed with narrow bricks in English bond, and features a chamfered plinth, timber framing in the eastern gable, a large rear-wall chimney, and a projecting oven at the back.
