South Trew Farmhouse

South Trew Farmhouse is a farmhouse dating from the early to mid 17th century, possibly with earlier origins, and features a 19th-century addition. The building has plastered cob walls and a gable-ended thatch roof, with two brick stacks: one at the right gable end and another axial rubble stack at the left gable end with a brick shaft. The layout consists of a three-room-and-through-passage plan, though it has unusual proportions; the lower room on the right is very narrow, and its stack may have been inserted later. The hall is fairly small, with its stack backing onto the passage, and its fireplace appears to be a later addition. The inner room is larger and has a gable-end fireplace. A 19th-century lean-to has been added behind the hall and inner room, and a staircase has been inserted into the passage.

The exterior is two storeys high with an asymmetrical front featuring four windows, which are early to mid 20th-century two-light casements. There is a small 20th-century lean-to porch towards the right-hand end with a part-glazed door leading to the passage, and a 20th-century conservatory porch to the left of centre.

Inside, the inner room has three chamfered and stopped ceiling beams, with the central beam showing mortices on its soffit that suggest it may have been reused for a partition. The open fireplace in this room has a chamfered lintel and a date stone of 1782 built into the top of the right-hand jamb, with the initials "I.B." inscribed on the top of the other jamb. The central room features a chamfered axial beam with run-out stops and a smaller fireplace with a plain wooden lintel. The lower room lacks visible early features. At the left-hand end of the house, the curved foot of a roof truss is visible, although access to the roof space in this area is very difficult. The rest of the house has a roof structure from the 18th century, consisting of simple crude A-frames with straight principal rafters.
