Saw Mill, possibly water powered, due to proximity to River Wear at Miniken's Canch.

Quarry, marked as Old on the 1st edition OS mapping, so out of use by 1855.

Ford Paper Mill. Established in 1838 by Thomas Routledge, the mill made paper from Esparto grass {2}.

Sand Pit.

Ballast Hill. A shipyard, (SMR 2773), was built against the western side of the hill.

Shipbuilding Yard, built partly on the west side of Ballast Hill, (SMR 2774) {1}. Two small and irregular shipyards lay on the Southwick shore of the River Wear by at least the 1850s, occupying the river strand up to the western flank of a ballast hill (Glasshouse Hill), the product of waste dumping from the Wearmouth Crown Glass Works which lay to the south of the yards. They were solely timber construction yards and contained only minimal facilities. The yards had gone by 1898.

Two small shipyards are shown on the Southwick shore of the River Wear. These are timber yards containing only minimal facilities. Buildings (no annotations describe functions) lie in the northern portion of the area, other than these, only cranes are marked.

By this time, the yards have closed {2}.

Wearmouth Crown Glass Works or Southwick Crown Glassworks. The works was opened in 1805. From c.1823 it was run by Atwoods, until c.1860 it produced Crown glass, thereafter, blown sheet. The Wear Crown Glass Company took over c.1869 and eventually the site was absorbed into Pickersgill's Shipyard {2}.

William Pickersgill’s first yard is thought to have been founded in 1838 in the North Dock area of Sunderland in partnership with another shipbuilder, a Mr Miller. In 1851, the business was transferred from the North Dock to Southwick, soon after which the partnership dissolved and the business was run solely by the Pickersgill family. The Southwick Yard produced only wooden vessels until 1880, mainly barques, brigs and snows, all types used in the coal trade. The last of these wooden ships, and the last constructed on the Wear, was the Coppename of 1880. The first iron ship launched from the yard was the Camargo.
William Pickersgill was killed in an accident in the yard in the early 1880s, and his son, William John, took over the yard in 1887. William Pickersgill and Sons Ltd. was incorporated as a private limited liability company in 1907. The main product of Pickersgill’s over the later nineteenth and the start of the twentieth century, was merchant vessels; mainly tramps, cargo-liners and colliers. During WWII, Sir John Priestman’s Yard (Castletown Yard) which lay to the north-west of Pickersgill’s yard was taken over and two new building berths were constructed at the yard.
Pickersgill's East and West Yards at Southwick were divided by a ballast dump, 90 feet high and 600 feet long, known as Glasshouse Hill. This was removed (providing almost 10 acres of additional land to the now amalgamated yards) subsequent to the merger of Pickersgill's Ltd. with S P Austin's and Son in 1954 (the company becoming Austin and Pickersgill Ltd.). Ballast removed was used to compact and raise the shoreline within the West Yard in which three realigned building-berths were then constructed. Facilities within this yard now allowed vessels to be built-up from pre-welded units of 30 tons each and up to a total vessel weight of 30,000 tons. The first ship from the new yard, the Essex Trader, was launched in 1958. In the East Yard, 24,000 tons of spoil and 3,800 tons of bedrock were removed and re-used to provide the foundations for a new quay wall. This yard was opened in 1960 and was used solely as an outfitting quay.
In 1965, a replacement design for the 'Liberty' ships (a design of Thompson’s Yard), built in the USA during World War II was prepared by Austin & Pickersgill. This became, as put into production, a five-hold 'shelterdecker' of 15,000 tons, known as the SD 14. In total, 211 of this very successful type was produced either by the Southwick yard or by licensees. The last of the type, the Sunderland Venture, was produced by the yard in 1983.
In the mid-1970s, Austin and Pickersgill began to construct bulk-carriers. In order to build these large ships efficiently, the yard was once again extensively developed and expanded, financed partly by the new owners, London and Overseas Freighters Ltd. (this company had acquired a 50% shareholding in the yard in 1957 and purchased the remaining shares in 1970) and partly by the Government. The redevelopment scheme was split into two main phases. The first phase, started in 1975, involved the construction of a partially enclosed building berth with adjacent stern and block assembly hall to launch ships obliquely down-river. Along with this facility, the existing steel shops within the yard were expanded and infrastructure within the yard improved. Although the phase II work was never implemented (this would have seen the construction of a 'mirror-image' building complex launching obliquely up-river) the yard as developed was one of the most modern in Europe. In 1977 it became a member company of British Shipbuilders.
1986 saw Austin & Pickersgill Ltd merge with Sunderland Shipbuilders Ltd. to form North East Shipbuilders Ltd. (NESL). Austin & Pickersgill became the 'Southwick Yard' of this company. Closure of NESL was announced in 1988 and the yard and all its facilities were demolished in 1990.

Six yards lie on the Southwick shore of the Wear. All are very simple, each equipped only with a smithy, cranes and, generally, saw pits. It is uncertain which of the yards was that originally owned by Pickersgill’s. The premises of Wearmouth Crown Glass Works lies immediately to the west of the yards.
Second Edition Six Inches to One Mile Ordnance Survey 1898, Sheet VIII SW
Buildings have proliferated within and around the edges of the yard. A slipway is shown running obliquely across the yard to launch downriver and a jetty projects at right angles to the river from the middle of the yard. A marine engineering works is marked beyond the eastern edge of the site and Wearmouth Crown Glass Works, on the eastern side of the yard, is now in disuse.
Third Edition Six Inches to One Mile Ordnance Survey 1921, Sheet VIII SW
The Queen Alexandra Bridge has been constructed and lies immediately adjacent to the eastern edge of the yard. The landing stage shown in the second edition survey has been enlarged but the slipway has been omitted from this survey, or has gone. A landing stage is marked at the eastern edge of the yard. To the west, the yard has expanded upriver, where it now runs up against a ballast hill (this was Glasshouse Hill, formed largely of waste products from the former Wearmouth Crown Glass Works, which the yard now overlies {2}.
