Shown on Ordnance Survey second edition of 1897. Sunderland Flint Glassworks was set up by Nicholas French in 1852 on Trimdon Street (HER 2819). In 1858 the business was bought by Henry Greener and James Angus, and thence traded as Henry Greener, The Wear Flint Glassworks. After Angus' death in 1870 Greener built a new glasshouse at Millfield in 1873. After Greener's death in 1882 the company continued as Greener and Co. but faltered and was ultimately bought by James Augustus Jobling, a Newcastle merchant. Jobling's works were renamed the Wear Flint Glass Works. The factory comprised a large rectangular glass house with four square chimneys and one circular chimney or glass cone. The works had a direct link to the NER Penshaw Branch Line (HER 2659). By 1941 the Wear Glass Works expanded north, probably the result of Jobling obtaining the British licence for Pyrex in 1922 from the American firm Cornings. Jobling also made lenses for road vehicles. By 1969 the glass factory had expanded massively, obliterating Diamond Hall (HER 13173), the Queen Alexandra Bridge Branch Line, Wearside Pottery and other works. By the late 1970s the site expanded to its current size. This required the demolition of parts of Carol Street, Cornwall Street, Leopold Street, Medomsley Street and Alfred Street.

The school building was part of Simpson Street School which also included a Grade II listed Boy’s school on Wellington Lane. The school is first shown on the 1895 Ordnance Survey, but it opened in 1867 as Deptford Yard Church of England School (HER 7232). The Girl’s and Infant’s school is a single storey structure constructed out of English garden wall brick work with four-pane sash windows and Welsh slate roof. A metal finial on top of a bell-cote is located in the central section of the structure. The original timber floors were replaced in the 20th century with a concrete surface in three rooms and metal shuttered doors were installed. In the 20th century the building was extended, and the structure was converted into workshops for Sunderland Coachworks and the premises of Meat Direct. The school was demolished in advance of the construction of a new road for the Sunderland Strategic Transport Corridor.

Shown on Robson's map of 1830. A large house in an isolated position within the field system. The building was owned by 'Snowdon'. Messrs Snowdon and Watson established the Diamond Bottle Works to the west of the house in 1852. The OS first edition map of 1858 shows Diamond Hall subdivided into 4 separate ownerships, one of which is a smithy. A slae plan for the Diamond Hall Estate in 1858 shows the 'mansion house' and the land divided into lots. The accompanying sale map shows the land 'late belonging to Frederick Snowdon esq'. Diamond Hall was demolished by 1969 for the expanding glass factory.
