An open rope walk is shown on the OS map of 1859 but not on the 1894 map, when it had been built over by a school and a number of other unidentified buildings, probably industrial in nature. It is not shown on an 1849 map, and is unlikely to have consisted of any substantial structures {1}.

These coal drops are of a type that would usually be fed from a railway line. One of the drops is of apparently 19th century stone construction and was located immediately behind an engine house shown on the c.1850 plan. It is probable that a wagonway or other track existed between the coal shaft (SMR 4118) and the engine house, although there is no map evidence for this {1}.

A roughly circular mound, measuring c45m in diameter, apparently with a spiral track leading to its top. It appears to be a spoil heap, and is shown on maps from 1859 to 1914, but is no longer shown in 1940. It is possible that this mound contained lead smelting waste, although it is unlikely that any ore smelting took place on the site. It is more likely to be either a coal heap/storage area from the coal mine to the north (SMR 4118) or a general waste tip containing spent tanning bark, coal ash or broken ceramic jars. {1}

A building referred to as the power house on a site plan of 1955, and referred to as the power house by the present managing director. It is not clear whether it housed a hydraulic engine or was a hydraulic pumping house. It appears likely to have been a source of hydraulic power for powering presses etc, in the pipe mill (SMR 4901) on the site. The structure was built between 1914 and 1940, relatively late for the use of hydraulic power, and consists of four stories, all presently unused. The lower floors have been unused since before 1955 and may contain the remains of hydraulic machinery {1}.

This building was constructed after 1859, probably in 1874, on the site of a number of earlier buildings. It was built as a pipe mill and probably contained the 6 hydraulic presses noted in a sale catalogue of 1884. The upper floor was rebuilt and re-roofed prior to 1980 to be used as offices, but currently houses welfare facilities. The lower floors are not used at present. The two northern corners of the original building survive at upper floor level. The southern face of the building was rendered between 1969 and 1980. Lead pipe was originally produced by soldering or welding sheet lead which had been rolled into a cylinder. Later it was produced by drawing and extrusion, in a similar way to the manufacture of wire. The pipe mill built in c.1874 would almost certainly have been producing pipe by drawing and extrusion. The earlier pipe mill, shown to the west of the main white lead stacks area on a plan of c.1850 is likely to have been producing pipe by welding. {1}

A jetty to provide lead works (SMR 4116) site level access to the river, built between 1827 and 1844. It may have been easier to move goods on the level and then to lower or hoist them rather than using an inclined plane. It seems to replace the use of the quay (SMR 4907) as the main point of site access from the river {1}.

The lead works (SMR 4116) site office, if it survives inside the later rebuilding, is probably the oldest upstanding structure on the site. It appears to have lain in the residential part of the original 2 acre site, and is apparently shown on the earliest map available of the site. It may have originally been housing rather than an office {1}.

From map evidence it appears that the house, called Low Elswick House from the 1894 OS map onwards, was built between 1802 and 1827, perhaps coinciding with one of the changes in partnership of the lead works (SMR 4116) which occurred during this period. It replaced an earlier partner's house probably located immediately to its south. The house is likely to survive within the present company offices, which comprise additional structures added up to at least the 1950s. Both the interior and exterior have apparently been much altered. The house was visited during the last re-listing but was not listed. {1}

A small (6m diameter) circular icehouse is marked on the c.1850 plan as a chimney. It is marked on the 1859 OS map as an icehouse, and is still marked as an icehouse on the 1:500 scale map of 1894 but is not shown subsequently {1}.

Worker's cottages appear to have been on part of this site from a very early date, from the first partnership of the lead works (SMR 4116) when three cottages were built, probably at the north end of the row. Nine cottages were noted as belonging to the lead works when it was offered for sale in 1884, although there may have been others located elsewhere on the site. The cottages were still shown in 1940. The front walls of the cottages are still visible in the wall at the edge of the road, as is a blocked semi-circular arch which may contain a drain. {1}
