Treworgan House

Treworgan House is a farmhouse dating from the 16th century, with extensions made by Robert Trencreeke around 1560. It is constructed from killas and granite, featuring granite quoins and dressings, and has a slate roof. The building has an 'L'-shaped plan, consisting of a main east front with three structural bays and a south limb, which is also three bays and of earlier date. The yard in the re-entrant angle is enclosed by a stone wall that connects to a cottage, which is not of special interest, on the west side. The main range includes a central sitting room with an axial stack to the left, a kitchen to the right, and a parlour in the corner with a rear wing that contains services and a drawing room at the west end, featuring a gable stack.

The house is two storeys high. The main front has a recessed entrance in the centre bay with a half-glazed door, surrounded by flush granite with a broad chamfer that ends in angled stops. There are similar flush three-light chamfered mullioned windows without labels. The building has stone stacks, including a large part-external gable stack to the parlour, which has been heightened in brick. The south range features a three-light stone mullioned window on the first floor and a smaller light within a chamfered surround below. Other windows were replaced in the late 19th to early 20th century. The end bay has ramp access to the upper floor, and within the courtyard, there is a lean-to with a slate roof over the entrance.

Inside, the main range has been converted into a living kitchen, featuring a gable fireplace at the north end made of architectural stonework, which includes late medieval mouldings and fluted pilasters with roundels. There is a moulded stone mantel shelf and a two-centred chamfered arch leading to the entrance of the older wing. The south gable stack, now the parlour, has a timber lintel. The rear wing has a chamfered two-centred arch leading into the end living room. The roof was not seen. Treworgan House was once the seat of the Trencreeke family, later the Polwhele family, and it provided shelter to General Fairfax during the Civil War.
