Main Group Of Farmbuildings, To North-West Of Thornbrough High Barns Farmhouse

The main group of farm buildings, located to the north-west of Thornbrough High Barns Farmhouse, was constructed in 1816 and has undergone some alterations in the late 19th century. The buildings are made of coursed rubble with stone dressings, featuring Welsh slate roofs, except for the barn which has stone slates and the east range that has 20th-century grey tiles.

These single-storey structures surround a yard that is open to the south, with a two-storey barn situated at the back of the north range. In the center of the yard, there is a later Dutch barn that connects to a loose box to the south. The north range includes two boarded doors set in alternating-block surrounds at the central gable end of the barn, along with four segment-headed arches on either side, one of which has been replaced by a later cart door and some others are blocked. The flanking ranges feature boarded doors, part-slatted windows, and some later openings.

The five-bay Dutch barn is supported by cast iron piers that are doubled to provide extra height, while the loose box has boarded doors and a hipped roof. The barn at the rear of the north range shows evidence of a removed gingang on the west side and has three tiers of slit vents in the north gable end. To the left of the barn, there are two shorter single-storey gabled projections with boarded double doors, one located under a segmental arch and the other under a timber lintel. A contemporary pent pigsty is situated between the former range and the barn.

At the rear of the east range, there are four boarded doors and part-slatted windows, while the rear of the west range features an arcade of four segmental arches, some of which are blocked and one is partly concealed by a 20th-century wing of a cottage. The altered cottage at the end of the west range is not of particular interest.

This group of buildings is listed partly for its historical significance as it is the earliest of the planned farms associated with Greenwich Hospital, for which a surviving plan is known from the Greenwich Hospital Visitations.
