Three parallel north-east to south-west walls 2.2m apart. All of the walls were of identical construction (Dearne's bond), with only two courses visible. They appeared to match up with buttresses present running down the length of the extant south western wall of the warehouse building (still in use as a retaining wall), and it is likely that, unless a cellar was present they would have continued below the flagstone floor as a support. The bricks used were likely to be of mid 18th century to early 19th century date. These walls appeared to have been built into the natural clay and the wall foundation cuts backfilled with redeposited natural, making the cuts extremely difficult to see. (1)
