Roseventon Farmhouse and Workshop to South East

Roseventon Farmhouse and the adjoining workshop to the southeast date from the 17th century, with extensions made in the 19th century. The farmhouse features painted cob walls, wooden lintels, and thin slate sills, topped by a steep corrugated iron roof that was formerly thatched, along with brick chimneys at the gable ends. The workshop and service area have a lower pitched roof and eaves. A large external stone breast is present on the northwest gable end. The building has a two-room single depth plan with a central stair, while the one-room service area to the southeast may be a remnant of an earlier three-room plan. The upper end of the farmhouse was remodeled around the late 17th century and again in the 19th century. The property stands two storeys tall on a steep slope at the rear.

The southwest front of the farmhouse is slightly irregular, featuring a two-window section on the left and a lower one-window section on the right. The house has a nearly central doorway with a four-panel door, the top panels of which are later glazed. The right-hand window has another window above it, while the left-hand ground floor window is wider, and the first-floor window is positioned farther to the right. All windows are four-pane horned sashes. There is a small blocked window opening on the ground floor, far right, which corresponds to the position of an internal oven. The service end of the front has a doorway on the left, now fitted with a 20th-century window, a small window opening in the middle with a 20th-century window, and an enlarged window opening above with a reused casement. The present doorway is to the right, leading to a larger doorway for the workshop at the far right.

Inside, the house has been remodeled and refloored in the 19th century, but a fragment of an ogee moulded muntin and plank partition survives beside the entrance passage between the rooms. The left-hand room (northeast) has a partly blocked and remodeled fireplace, while the right-hand room features a large splayed fireplace with a cambered and chamfered oak lintel. To the right of the hearth is a large stone oven with an arched stone doorway. This building is a rare example from before 1700 in a region that was once rich in mining, now mostly populated by late 18th to early 19th-century miners' cottages.
