Description

The Granary is a two-storey outbuilding that has been completely rendered and painted, featuring a slate roof with red ridge tiles. It has an L-shaped plan, with a wing extending forward on the right side, which has an end gable facing the front. The lower level includes a plain door, with a 6 over 6 pane sash window above it, accessed by a flight of stone steps that replaced a previous door. To the left and set back are two additional bays, along with a second flight of steps leading to a part glazed door at the top. This wing also has a modern stack on the left gable. The rear elevation has not been seen. Although the interior was not inspected during the resurvey, it is currently in domestic use after being converted in the late 20th century.
