12, Foundry Street

12 Foundry Street is a former warehouse for Baldwin's Foundry, built in the mid-19th century. The building is constructed of red brick with blue brick dressings and features a hipped slate roof along with some structural ironwork. It stands two storeys tall with a basement at the street front and has 13 bays. There is a wide arched entry on the left side of the elevation and a doorway to the basement towards the right end. Most of the lower windows are made of cast iron, although there are two sash windows on the right, which may indicate the location of a former office. The upper windows are all cast iron and feature segmentally arched brick heads. The eaves are dentilled, and there is a stack on the right gable.

To the left, there is an additional single-storey bay with two loading doors positioned above ground level. The rear elevation has an open arcade on the ground floor supported by cast-iron columns and lintels, with brick relieving arches above. The ground floor elevation is symmetrical, featuring a central wide loading door flanked by two outer doorways. The central bay on the upper storey also has a loading door, and all rear windows are cast iron with segmentally arched blue brick heads.
