Description

Todsworthy House is a farmhouse dating from the early 18th century, possibly incorporating an earlier structure, with additions and alterations made in the 19th and 20th centuries. The building is constructed from rendered stone rubble and features a half-hipped slate roof, partly covered in asbestos slate, with a slurried slate roof over the shippon. It has brick chimney stacks on the sides.

The layout consists of a two-room plan, with rooms of equal size on either side, each heated by an end stack, and a central entrance passage. To the rear left, there is a one-room plan addition for service, which is two stories high and likely dates from the late 18th to early 19th century. This addition was extended along the entire rear of the house in the late 20th century. There is also a single-storey shippon addition from the 18th century on the left side.

The exterior is two stories high with a symmetrical five-window front. The central entrance features a 19th-century panelled and glazed door with a timber lintel and a shallow hood supported by wooden piers, flanked by 19th-century buttresses. On the ground floor to the left, there is a 20th-century glazed door set within an attached greenhouse, alongside a 19th-century 12-pane sash window. To the right, there is a 19th-century 12-pane sash and a 16-pane sash window. The first floor has three early 18th-century 12-pane sashes with thick glazing bars on the left and one on the end right, while the second window from the right is a 19th-century 16-pane sash.

The left side features a single-storey shippon lean-to with a door on the side and a ventilation slit at the front, along with a door and a two-light casement window to the left. The rear addition on the left has a 20th-century porch and door, with a 20th-century window on the first floor. The right side has two 19th-century buttresses. At the rear, the addition on the right has three 20th-century windows on the ground floor and two on the first floor, while the service room addition has been extended to the left along the entire rear in the late 20th century. The interior is not accessible.
