Description
Castle House is a house that was formerly an inn, built from squared rubble stone and topped with roofs made of imitation slates. The building is two storeys tall and has an L-shaped plan, featuring a hipped crosswing on the left side with a roughcast chimney on the east wall, and a main range on the right side that has a stone ridge chimney at its original west end. This main range has been extended by one bay to the west and sits on a raised plinth.
The windows are hornless 12-pane sashes with cut grey stone voussoirs and stone sills. There is one sash window on each floor of the crosswing, followed by three on the two-bay main range, which also has a door in the left bay. There is a straight joint where the addition meets the main structure, and this addition features a similar sash window above the door and a cross-window that has replaced a sash, all with sandstone voussoirs. The main entrance door is a six-panel design, with four of the panels being glazed and topped with a three-pane overlight. It is sheltered by a flat timber hood supported by brackets.
On the left side wall, which faces the river, there is a large chimney in the center. To the left on the first floor, there is a blind window, while to the right, there is a 9-pane window. The ground floor features another 9-pane window in the center and a basement door flanked by two 6-pane windows. The west end wall of the addition has brickwork in the gable, and there is a rear wing behind the building.
The interior has not been inspected.
