Ruins of High Dyke with associated outbuildings, paddocks and limekiln

High Dyke is a farmstead that originated as a drovers' inn in the late 17th century, with substantial later additions mainly dating from the 18th century. The complex has been disused since the late 19th century and is now ruinous.

The main house is constructed of Yoredale sandstone coursed rubble with millstone grit quoins and dressings, originally roofed in stone slate. The central section is a 2-cell building of single depth with a stair turret at the east end of the rear (north) wall. The original house has been reduced to a single storey and is now roofless. It is roughly quoined with simply formed windows featuring simple monolithic lintels, most of which are now blocked. The central entrance is flanked by two 2-light windows, with a third single-light window to the west. A lean-to porch with a west doorway covers the central entrance. The rear north wall contains a single single-light window serving the stair turret. A large stack of stone now fills the angle between the south wall and the east wall of the porch, not recorded in 1978.

To the east is a 2-storey single-cell addition that stands to full height and retains its stone slate roof, though it is poorly bonded into the east gable of the original house. This addition is neatly quoined and features well-dressed monolithic lintels, sills, jambs and squared mullions to its two 2-light windows. A later-inserted front doorway, more roughly formed, provides independent access.

To the west, the original house is knocked through internally to an attached barn, which is now roofless. The barn has a large blocked opening in its south wall and ventilation slots in its north wall.

The interior of the original house has been gutted and knocked through to the barn following removal of its west gable wall. The east gable retains a fireplace at first floor level served by a flue corbelled out into the roof space of the 2-storey addition. A doorway connects to the east addition south of the stack at ground floor level. The east addition has also been gutted with loss of its upper floor joists but retains some plaster to the walls. Its east gable contains a ground floor fireplace flanked by small cupboard recesses, and a square pitching window has been inserted into the north wall at first floor level.

Associated with the main house are several outbuildings. A lean-to cart store stands east of the 2-storey addition, with a doorway and cart entrance formed from well-dressed and margined gritstone facing east, opening directly onto the old road along the edge of the unenclosed moor. A byre is attached to the west of the barn, projecting forward of the south wall of the main house, open to the south and neatly quoined, retaining part of its stone slate roof. Immediately south of the original house stand the ruins of a further farm building, approximately square in plan. Approximately 40 metres to the northeast in the unenclosed moorland, the ruins of a limekiln survive, retaining its drawing arch. Small drystone-walled paddocks extend south of the buildings.
