Side Aisles

Reconfiguration of the Support Bracing in the Side Aisles

Both side aisles have undergone remodelling during the life of the barn due to necessary repair, reinforcement or restoration. There is tangible evidence of at least three stages of construction - the original mid 16th century configuration, a post 1700 reinforcement and the latest 1995/6 restoration.


Figure i - The original mid 16th century design used curved rear shore bracing from the arcade post to the aisle tie. The braces and wall ties are attached to the arcade post with pegged mortice and tenon joints.

Figure ii - After c. 1700 reinforcement timbers were added to the aisle tie beams. These were attached to the arcade post with nailed dovetail joints and then, together with a post to wall base diagonal braces, fastened with forelock bolts to the existing tie beams.
