This series of vaults and tunnels was found during archaeological investigations in 2022 prior to the redevelopment of the site (report 2024/24). They were found following the demolition of the Dex Garage, but were probably associated with the Northumberland Coach and Harness Manufactory (HER10611) which stood on the site previously. The vaults were aligned northeast-southwest and were approximately 5m wide, constructed with parallel sandstone walls, arched brick ceilings and concrete floors. They were connected on the western side by a narrower tunnel running at right angles to them. Further vaulted brick tunnels were found in a trial trench (6) to the southwest.

These east-west anti-glider ditches were identified by a geophysical survey (event 4569 report 2016/176) and subsequently investigated by trial trenching (event 5525 report 2024/13, and event 5526 report 2024/14) in advance of a housing development. One ditch survived as an earthwork in the eastern part of the area. The ditches measured between 0.30m and 0.48m in depth and between 1.10m and 2.50m in width. There was no evidence of associated banks.

Stella North Power Station was built in the early 1950s in conjunction with Stella South Power Station (HER1705) and stood opposite to it on the north bank of the Tyne at Newburn. The four cooling towers to the south of the main buildings were 240ft high. Both power stations are shown on the Ordnance Survey 1967 map and were demolished in the 1990s.

During the construction of houses on the Pennywell Estate in March 1950, workers reported finding 'the bones of several bodies'. The Sunderland Antiquarian Society reported the find in their annual report (not yet reviewed for this HER entry). The burials were attributed to a Civil War action and were described in a letter by Joseph G Hayden to the Sunderland Daily Echo and Shipping Gazette as 'men of medium build and in their late twenties'.
The find was in the local press again in 1954, when the depth of the skeletons was given as 'about 18 inches below the surface' and dated to October 1949. A field nearby was named as 'The Battlefield'.
The find was reviewed by Sunderland Global Media in early 2024, with images attributed to a newspaper article of the time, but this was not referenced and has not been located.

South Shotton Edge House was listed Grade II in 1987 with the following description:
'House, early C19. Tooled stone front, other walls roughly-squared stone; tooled-and-margined quoins and dressings; Welsh slate roof. 2 storeys, 3 bays, symmetrical. Central renewed door with overlight; 16-pane sash windows with slightly-projecting sills; all openings in alternating-block surrounds. Gable coping returned on deep footstones; stepped-and-banded end stacks. Similar door and fenestration to rear.
Formerly the Red Lion Inn, on the Great North Road.'

This gully was excavated in advance of a proposed housing development. It had been previously radiocarbon dated to 162 calBC - 5 calAD. An 11.75m length of the gully oriented north-south was excavated, having been truncated by a furrow and later ploughing. It measured 0.70m wide and 0.21m deep and had concave sides and a concave base. It was interpreted as a component of a wider field system associated with a settlement elsewhere, as no associated features had been identified within the development area.

This carriageway was excavated in advance of a proposed housing development. It led east from Peareth Hall (Usworth House, HER 8471), built around 1750, through the grounds of the hall towards Great Usworth village. A 20m length of the carriageway was excavated and recorded. It was oriented ENE-WSW and constructed on a foundation of sandstone fragments with a line of kerb stones along each edge. These appeared to have been angled away from the carriageway surface, possibly to encourage water to run off it. The foundation was overlain by a compacted and worn metalled surface, also of sandstone. In places the carriageway had subsided slightly into former furrows. Repaired wheel ruts indicated a distance of 1.35m (4 foot 3 inches) between the carriage wheels.

Heathery Lane Cottages are shown (though not named) as a single block on the Ordnance Survey First Edition map on the northern side of the junction between Heathery Lane and Salter's Lane, within a small enclosure. Later maps show another building to the north (rear) of the cottages, which are shown as two dwellings each with a small garden area, enclosed by a larger area depicted as an orchard.
The cottages are built in randomly coursed sandstone ashlar with finely dressed quoins, window surrounds and cills, and a slate roof. An extension has been added at the western end in uncoursed squared rubble.
