12 and 14, Hammerton Street

12 and 14 Hammerton Street is a former Co-operative Society store, now a video shop, with upper floors integrated with the 1905 extension at No. 10 to the left. The building is dated 1862 at the first floor and has been altered over time. It is constructed from punch-dressed sandstone ashlar with freestone dressings and features a concealed two-span hipped roof, likely covered in slate. The rectangular plan is situated on a corner site and consists of three storeys and four windows. The ground floor has been entirely altered, but the upper floors retain rusticated quoins, a sill band on the second floor, and a moulded cornice with a blocking course. The first floor includes sashed windows without glazing bars, while the second floor has four-pane sashes, all with raised sills and plain rectangular lintels. In the center of the first floor is a stone plaque with raised lettering that reads: "BURNLEY EQUITABLE/ CO-OPERATIVE/ AND INDUSTRIAL/ SOCIETY & STORE/ 1862," flanked by cruciform tie-plates. The four-window right-hand return side facing Hargreaves Street has matching fenestration.

Inside, the upper floors are integrated with No. 10 and feature construction similar to cotton mills, with cast-iron columns and beams, a good Jacobean-style staircase, and some other contemporary decoration. This building was the first designed and built for the Burnley Co-operative Society, which was formed in 1860. It forms a group with its 1905 extension at No. 10 and with Nos 9-29 opposite, collectively representing the growth of the Burnley Co-operative Society from 1862 to 1905.
