Barn at Great Pool Hall

The barn at Great Pool Hall is a large structure divided into three main sections. It is primarily built of rubble stone that encases a partial timber frame, topped with a corrugated sheet roof. The oldest part of the barn is located in the center, featuring cart entrances that extend as porches to both the north and south. The southern entrance has a hipped roof and a timber lintel above modern steel doors. To the left of this entrance, the upper bays are part of a later addition to the original barn, which is partially hidden by lean-to additions. This section is made of rubble stone and includes a high door on the left gable, which is covered with weatherboarding, and two ventilation loops resembling arrow loops in the stonework to the right of the doorway. The right-hand bays are obscured by a lean-to stable that fills an earlier cart-shed addition.

On the northern elevation, there is a doorway in the western extension of the barn that aligns with the southern doorway. The original section beyond this has weatherboarding and corrugated sheet cladding over a timber frame set on a stone plinth wall. An early addition, a northern transeptual cart entrance, aligns with the southern entrance and features a plain gable rather than a hipped one. This entrance is made of stone. The rear of the eastern addition shows remains of timber framing, although it is roofless and fire-damaged.

Internally, the timber-framed north wall of the original barn is clearly visible, along with the wall posts of the original south wall still apparent beneath the later stone cladding. The barn features four open roof trusses that are braced from the wall posts, with raking collar struts and three tiers of purlins. Similar trusses against the east and west gable walls, both made of stone, likely indicate the boundaries of the original timber-framed building. There are two windows in the west wall, both retaining remnants of diamond timber mullions. The heavy roof trusses in the cart bays suggest these may have been relatively early additions to the original structure. Additionally, there are paired vent slits on either side of the southern cart entry, and the eastern barn has a stone south wall with vent slits designed like arrow loops.
