Description

Bunkers is a house dating from the 17th century, with a later 17th-century chimney and renovations made in the late 20th century. The building features an exposed timber frame on the first floor with red brick infill, while the ground floor has been renewed in red brick. It has a steep old red tile roof and is two storeys high with attics, facing north. The entrance is located in a lobby by the stack, which is the third from the east end. The house has a three-cells plan, originally with an unheated west room, and the stair is likely located at the rear of the chimney.

A large chimney rises through the ridge and has three conjoined square flues with a panelled side facing the front. There are two fireplaces on the ground floor and a brick fireplace with a chamfered and hollow stopped lintel in the chamber above the hall. The windows have irregular fenestration, featuring four small-pane casements on each floor. The bays on the front have four, three, five, and an unknown number of panels, with the narrowest bay serving as the entrance and chimney bay. The roof is a clasped-purlin type with collars and square butted scarf joints in the purlins and wall-plate, and there is a straight brace in the front wall. A bread oven is said to have been removed to make way for a new staircase in the entrance lobby. Photographic evidence suggests that a timber-framed chimney once existed in the same narrow bay before the current brick one. The axial floor beams in the rooms on either side of the stack show a higher degree of finish in the east end room, likely the parlour, while there is a cross-beam in the west end room.
