Manor House

Manor house, dating to the late 16th century, with alterations in the 17th and 18th centuries. It is constructed of rubble stone with dressed limestone detailing, featuring a Welsh slate hipped roof and rendered or ashlar stacks with moulded stone cappings. The building has a square through-passage plan, and incorporates a bay of a former barn (listed separately) to the east.

The main front is two stories high with three windows. It features casement windows. A central 20th-century door is set within a moulded stone surround. On either side of the door are four-light, hollow-chamfered mullioned casement windows with moulded headed lights. A moulded string course runs over the door lintel, continuing down to a cyma-moulded plinth. The first floor has a four-light mullioned window matching those below, on either side. A string course is present, leading to a plain blocking course with a saddleback coping.

The left, or garden, front is similar to the main facade, but includes a half-glazed door to the left of the centre. An 19th-century hipped attic dormer with a two-light casement has been added. The right return has an eight-pane sash window on the ground floor, while the first floor features a three-light and a two-light mullioned casement with arched lights. The second floor has a three-light mullioned and transomed window with reused arched lights and a hoodmould, with string courses continuing upwards.

At the rear, a planked door is set within a beaded case to the right. Three four-light hollow-chamfered mullioned and transomed windows, together with a three-light leaded casement, are positioned to the left. The first floor has a three-light mullioned casement and a 20th-century mullioned casement. Two gabled dormers with two-light casements are on the left side, and the eaves have been raised in brick to the right.

Internally, a room to the right of the entrance has a stone Tudor-arched fireplace, 17th-century wainscot panelling, some 18th-century panelling, six-panelled or wainscot doors with cock's head hinges in ovolo-moulded cases, and exposed joists. A room to the left of the entrance has a stone Tudor-arched fireplace inserted into an open fireplace. Other stone Tudor-arched fireplaces can be found in the rear sitting room and on the first floor.

The western bay of the barn was incorporated into the house in the late 17th century, and a floor was inserted. During 20th-century renovation work, a dais or platform was discovered against the east timber-framed partition in this bay. The lower ceiling height and exterior window level of the east half of the house; the thick internal walls, and the use of poorer rubble stone, indicate an earlier structure, rebuilt around 1700, when the current facades and window arrangement were added.

The Manor of Hill Deverill was held by the Ludlows family from the 14th century and passed to the Coker family in the 1650s, then to the Duke of Marlborough in 1738. The building is likely associated with the Coker family, although it may represent a rebuilding of an earlier structure. The house, associated farm buildings, and Chantry Cottage occupy a moated site.
