No. 4 Pollen Street is a house that has been converted into a shop and flats. It was built around 1725 and refaced around 1780. The building features Flemish bond brickwork and a Welsh slate mansard roof with a brick chimney. It has three storeys and an attic, with a two-window range. There is a moulded cornice and a mid-18th century flat timber hood above a square-headed doorway, which has an overlight and a 20th-century door. The ground floor is finished in 19th-century stucco, with a 20th-century glazed door set in an inserted doorway to the left. The first floor has gauged red brick flat arches over 20th-century casements, while the second floor features late 19th-century four-pane sash windows. A stone cill band runs along the first floor, and there is a stone parapet above. The building has flat-roofed dormers.

Inside, there is a mid-18th century panelled room at the front of the ground floor, and a fine mid-18th century dog-leg staircase with turned balusters set on a closed string, featuring panelled bases. The interior also includes mid-18th century panelled doors and moulded cornices above.
