Old Overtown House

Old Overtown House is a farmhouse with an attached barn, now incorporated, dating from the early to mid-17th century. An addition was made in 1660, as indicated by the inscription "J.D." on it. In the 18th century, a barn was added, which was later incorporated into the building in the 20th century. The house is constructed of random rubble and ashlar limestone, with ashlar chimneys and a stone slate roof. It is two storeys high with an attic, and has an L-shaped plan due to an addition to the east end.

The north-west side of the house features the earliest section, with a mix of window styles. There is one 3-light chamfered mullioned casement window on the ground floor; otherwise, the windows are small-paned timber casements. An early 18th century oeil-de-boeuf (a round window) is set into the wall to the right, and a gabled dormer window with a small-paned casement is above. The barn on the right has glazed panels in the former doorway, still visible beneath a timber lintel. A 16th century casement window was inserted in the 20th century, a three-light window to the ground floor and a two-light window above, both with round-headed lights.

The north-east end has the gable of the original house, featuring a moulded cap to a gable-mounted chimney. The ashlar elevation of the wing has a single ovolo-moulded mullioned casement window on each floor, with a hood mould. A pedimented doorway is on the right, with an inscription on the pulvinated frieze. It has a moulded architrave to a 3-centred arch, a moulded keystone and imposts, and double 3-panel doors. An early 18th century oeil-de-boeuf is set above, with paterae and a hood mould.

The rear of the house has a projecting chimney with two rebuilt diagonal shafts to the gable end of the wing. The single-window fenestration on the rear of the wing mirrors the front. A projecting stair turret is in the angle. 20th century casements are found on the main range and the former barn.

Inside, a room in the wing has a moulded Tudor arched stone fireplace. The house forms a group with Old Overtown Cottage to the north-east.
