Corstage Farmhouse

Corstage Farmhouse is an early 18th-century farmhouse that features mid 19th-century windows. It is constructed of Flemish bond brown brick and has a graduated Welsh slate roof with a stone ridge, along with two gable and one ridge brick chimney. The building has a rectangular plan and is two stories tall with an attic, presenting a four-bay south front. There are plain bands at both the first and second floors. The windows are two-light casements, some of which have glazing bars, set in plastered plain architraves with deep wedged lintels and slightly accentuated keyblocks. The original doorway, located in the second bay, has been replaced with a window, and the door is now positioned at the right end, also in a similar architrave. The attic level contains two four-pane casements and a blocked window. There is a lean-to addition on the left side, and the bands continue around the building.

Inside, the central room features an inglenook fireplace with stone seats and niches. The bressumer and ceiling beam are chamfered and have tongue stops. At the rear, there is an original dogleg staircase with a heavy handrail and a continuous square newel post, although the balusters are missing. An upstairs door has two fielded panels.
