Description
Glanmarch is a two-storey building constructed from whitewashed rubble stone, topped with slate roofs and featuring whitewashed stone end stacks. The front range, which is three windows long and offset to the left, has hornless 12-pane sash windows with timber lintels on the upper floor, while the ground floor showcases stone voussoirs and stone sills. The left ground floor sash has been replaced by a 12-pane casement. A 20th-century door is located at the center, sheltered by a 20th-century gabled open porch. The right end wall includes a small square loft light, while the left end is windowless. The rear of the building does not have an outshut but features a northwest rear wing that is two-storey and has a 20th-century end stack, with an outshut to the rear. This section includes a door and a 12-pane sash with stone voussoirs, along with another 12-pane sash above that has a timber lintel.
Inside, there is a very large fireplace with a timber lintel in the left ground floor room.
