Old Sontley Hall

Old Sontley Hall is a building featuring a combination of brick and timber-framing, with white-painted brick nogging and a slate roof adorned with red ridge tiles and brick chimneys. The oldest part of the house consists of a two-storey section that runs parallel to the road. The ground floor is made of brick and has a 20th-century door on the left, along with two windows that have late 19th-century brick lintels and sills. The upper floor includes an off-centre inserted casement window, flanked by herringbone pattern timber framing. To the right of this window, there is a section of close studding with a blocked window above it, and additional herringbone pattern framing to the right.

On the right-hand return, the gabled end features a brick-built ground floor supported by brick buttresses. The upper section has much-altered timber framing with an inserted central window, a jetty at the eaves level, and late 19th-century mock timber-framing within the gable. Attached to the right is a lean-to brick extension that dates from the late 18th century.

The building was further extended with a range from the late 19th or early 20th century that projects forward from the main structure and runs at right angles to it, featuring a gable facing the road. This extension is constructed of brick with mock timber-framing in the gable and includes a series of gabled dormers on the left-hand return side. There is also a gabled block that projects at an angle, with a rendered ground floor and timber-framing that reflects 17th-century character. To the left of this block, there is another range from the 19th century that shows signs of having incorporated a stone building.

The interior was not accessible during the 1996 survey, but the plan form is described in P Smith's "Houses of the Welsh Countryside" (1988, p. 459) as being of the internal chimney and lobby entry type. The original list description from 1952 mentions fragments of wall paintings.
