Great Tregastick

Great Tregastick is a farmhouse, now a private house, dating to around the middle of the 17th century. It was extended to the rear with outshuts built around the late 18th or early 19th century. The construction is of stone rubble, with some areas rendered and slate-hung above the ground floor on the front elevation. The roof is of asbestos slate with gable ends, extending over the rear elevation in the outshuts. Stone chimney stacks project from the gable ends, and a lateral chimney stack with a brick shaft marks the junction of the main range and the outshut.

The original 17th-century range likely had a 2-room plan, potentially with a through passage, containing a hall-kitchen on the left and a parlour on the right. Both rooms were originally heated by end stacks, each with a large clay oven. A rear outshut was added around the late 18th or early 19th century, creating a double-depth plan. This incorporated a larger kitchen to the back right, heated by a fireplace positioned to the rear of the original through passage, and a dairy to the back left. A staircase was inserted into the through passage.

The two-storey front has a regular 3-window arrangement. The ground floor features a mid-19th century 3-light casement window with glazing bars to the hall-kitchen on the left, and a circa mid-19th century 2-light casement with glazing bars to the right, both with original 17th-century chamfered timber lintels with straight-cut stops. A mid-19th century stone lean-to porch with a slate hipped roof and a 20th-century glazed door is positioned near the centre of the front elevation. The first floor windows are similarly dated, with a mid-19th century 3-light casement on the left, a mid-19th century 2-light casement in the centre, and a 20th-century casement on the right, all with glazing bars. The roof eaves were probably raised when the outshut was added to the rear, and the roof pitch altered.

Inside, the probable hall-kitchen on the left has a circa mid-17th century chamfered timber lintel to the fireplace with straight-cut stops, and a large clay oven. The probable parlour on the right has a reduced ovolo-moulded timber lintel to the fireplace with an ogee stop on the left, and a large clay oven. The kitchen in the outshut has a circa late 18th or early 19th century fireplace with a large clay oven. A circa late 18th or early 19th century staircase is located in the passage, with a balustrade replaced in the 1970s. The roof timbers have not been inspected.
