Description
Greenhill Farm is an early 19th-century, two-storey house constructed from rubble stone and finished with roughcast painted cream. It features a slate roof and brick stacks at both ends. The upper storey has four 16-pane hornless sash windows, while the lower storey includes tripartite sashes on either side of a central doorway, which is topped by an added canopy and has a panelled door. At the rear, there is a continuous outshut that has three half dormers, each with 2-light, small-pane casements. Additionally, there is a boarded-up opening to the right, resembling a similar casement to the right of centre, and a boarded door to the left of centre. The building was not inspected at the time of the survey in September 1997.
