The current timber yard is established in the building of a former foundry. 1893 maps name this as the Victoria iron foundry. The foundry expanded into the east side of the polygon and by 1931 is named as the New Foundry (Brass and Iron). Most of the earlier parts of the building have been demolished and are now replaced by the open timber yard although some structures in the west of the building do date to this phase. This was previously an area of piecemeal enclosure. The enclosures were probably of an early date as these irregular fields are near to the original Saxon settlement of Barnsley (Elliot 2002, 26-7). There is no legibility of the former field pattern.
