Description
Longcross Farm is a long farmhouse constructed from lime-rendered stone rubble, topped with a thatched roof and featuring brick stacks at the ends and along the ridge. The building is a single storey with an attic. The original section on the right (west) has three dormers, each with thatched gabled roofs, boarded surrounds, and 12-pane sash windows. There are three larger windows on the ground floor, with a doorway located to the centre right that has a boarded door and an overlight. Additionally, there is a small staircase window situated between the two left windows.
To the left is a later wing that is contiguous with the original unit, marked by a stone pier attached to the front wall. This wing has its own separate door, a sash window, and a flat-roofed extension, which is battered.
The older unit on the right retains a fireplace with a bressumer and an old bread oven, with stone stairs beside it and a large chamfered and stopped cross beam. There is a partition that divides off an inner room to the right, which features a boxed-in beam. The A-frame roof is reported to survive, complete with two rows of purlins.
