East Tremar Farmhouse

East Tremar Farmhouse is an early to mid-17th century farmhouse with a later 17th century addition, substantial rebuilding circa the mid-19th century, and some 20th century alterations. It is constructed of slatestone and granite rubble with granite dressings. The roof has a tiled front slope and a rear slope of slate and asbestos slate, with ridge tiles and gable ends; rendered shafts enclose the gable end stacks.

Originally a three-room plan house, the farmhouse now retains the lower end room and passage. The passage was likely a cross passage, and a straight staircase was inserted into the rear of the passage in the 19th century. A solid wall runs along the right side of the original upper end. The lower end room is heated by a gable end stack on the left side. A small, unheated dairy was added to the lower left end in the later 17th century. Circa the mid-19th century, the upper end was demolished and rebuilt, the rear wall of which appears to survive at a lower level. The 19th-century rebuilding consists of one room with an end stack and a smaller, unheated room to the right end.

The two-storey front of the farmhouse has two bays to the left of the original structure. The first floor has two 2-light casements in granite, with chamfered surrounds and 20th-century casements, each with a small gable and bargeboards over. The ground floor has a similar 3-light granite window with a hood mould to the left; a doorway to the passage is to the right, featuring a 4-centred arch with hollow-chamfered reveals and recessed spandrels with roundels. Quoins are visible on the left side, and the later 17th-century lean-to dairy has a 2-light chamfered granite casement with a hood mould and a single chamfered granite light. The left side of the dairy is roofed with scantle slate and has a 2-light 19th-century casement with a timber lintel. To the right of the original range, there is a straight joint, and 20th-century casements at ground and first floor levels, the first floor window topped with small bargeboards. An axial stack is present. The end bay to the right has a 2-pane light at ground floor and a 2-light 20th-century casement at first floor. A single-storey rendered porch with a 20th-century door and window is on the end right. At the rear, an 8-pane stair light of the 20th century is located behind the passage. The rear wall of the 19th-century range steps up at first-floor level.

Inside, the lower end room has a slate floor and a gable end fireplace with a granite monolith jamb and a cloam oven to the rear right. A stud partition wall separates the room from the passage. The dairy has a slate floor, a rubble partition creating a separate pantry with slate shelves. The first-floor room has been partitioned, and the feet of the principal rafters are boxed in. In the roof, one truss is visible, halved and pegged at the apex, with chamfered principal rafters and a chamfered collar, also halved and pegged. A blocked fireplace is located on the first floor.
