Lanlawren And Barn Adjoining On West

This is a manor house dating from around the early 17th century, with later additions in the 17th century, 18th century, and early 19th century. An extension to the north forms a cross wing, and a further extension exists to the south, alongside a rear dairy with a lean-to roof. The building is constructed of rubble stone, partly rendered on the north side, with a slate roof. The right-hand end is hipped, while the left is gabled. The south wing has a lower roof with a hipped end and an asymmetrical half-hip to a projecting rear wing. A stone chimney with a brick shaft is incorporated into the rear elevation by the later addition of a dairy, and there is a rendered stack on the right-hand end.

Originally it may have been a single-depth, two-room plan with a cross passage, but later additions have created a three-room plan, incorporating a two-storey porch, a cross passage, a kitchen, and the rear dairy. The west front has a regular four-window arrangement, with a projecting two-storey porch with a gabled roof to the left of centre. The porch has a three-centred, chamfered granite arch with a reused timber lintel on the interior, and a wide timber entrance door with an ovolo-moulded doorcase and plain stops. The left-hand wing has no windows on its west front. To the right of the porch are two nine-pane sashes, with an ovolo-moulded timber lintel above each. A twelve-pane sash, without horns and under an unmoulded lintel, sits further to the right, showing evidence of a previous extension. On the first floor, there are two-light casements with eight panes per light, on both faces of the porch and three twelve-pane sashes to the right, with ovolo-moulded lintels to two of them. The mullions on the porch windows have heavy ovolo moulds. A large buttress extends along the left-hand hipped end.

A two-storey barn of rubble stone with a slate roof projects to the rear of the left-hand wing. Inside, the room on the north side and the rear kitchen have widely spaced, roughly cut beams. The fireplaces are later additions, and a framed staircase is present. The roof over the central 17th-century range of four bays has slightly chamfered and cambered roughly cut collars, with additional collars introduced later.

The manor was associated with Trethake in 1207 and was owned by the Walensis family. Subsequent owners included the Boneface, Cavells, and Hawkey families.
