Trethake Mill House

Trethake Mill House is a mill house for Trethake Water Mill, likely built in the late 18th century and remodeled around the 1840s. It was restored in 1983 and 1984. The house features rubble stone construction, which is partly rendered on the left-hand gable end, and has a slate roof with brick stacks at the gable ends. The front elevation has brick segmental arches over all openings. Originally, the house had a single depth plan with two rooms and a passage, but it has been extended to the rear with an outshut.

The building is two storeys high with a symmetrical three-window front and a central six-panelled door. The left-hand window is a tripartite replacement sash with glazing bars, while the right-hand window is a 16-pane sash without horns. On the first floor, there are three 16-pane replacement sashes. There is a single-storey outbuilding attached to the left-hand gable end, which is also made of rubble stone and has a slate roof. Inside, there is a large fireplace in the rear left-hand gable end, and a cloam oven marked "Bideford" that is partly blocked.
