Description

Newton House is a house dating from around the late 16th century, with significant extensions and remodelling in the mid to late 19th century. It’s constructed from stone rubble, with the east front rendered and part of the rear slate hung. Ashlar granite is visible on the north elevation. The roofs are slate, with double hipped ends to the front and hipped ends to the rear of both the left (south) and right (north) ranges. A rear wing on the northwest is offset and has a gable end. There are two projecting side lateral stacks on the right side of the north range, two projecting side lateral stacks on the left side of the south range and an axial brick stack in the northwest wing.

The original plan is uncertain, but evidence suggests earlier remains in the north range and northwest wing. The north range likely began as a two-room plan with side lateral stacks, and the northwest wing, which also formed the rear wing of the coach house and stables (listed separately), had a late 16th century segmental, hollow chamfered arch with large ball stops in the south gable end. In the mid to late 19th century, the house was considerably altered and a further one-room range was added to the south, heated by a projecting side lateral stack. The plan was likely altered to its present arrangement, with a main entrance on the east leading into a large stair hall. A reception room is to the left in the new addition on the south, and two reception rooms are to the north, heated by side lateral stacks. The rear northwest wing became the back kitchen, and a single-storey one-room extension was added on the right (north) side.

The exterior is two stories. The entrance features a reset 17th-century granite chamfered basket arch with diagonal stops and a hood mould. There is a four-pane sash window above, a 12-pane sash above the entrance, and an early 19th-century 16-pane sash to the right. The interior is largely 19th century, with high ceilings and a remodelled 19th-century stair. The rear northwest wing contains a chamfered segmental granite arch with large ball stops. The first floor was not inspected.
