Description

3 Llewelyn Avenue is a three-storey building with an attic, featuring four bays. It is similar in design to No 1 Llewellyn Avenue and No 114 Mostyn Street. The building has a slate pitched roof with two segmental-headed dormers. The facade is made of stone and includes a toothed eaves cornice. On the second floor, there are four round-headed windows with pilasters, moulded archivolts, and panelled aprons. The first floor has four sash windows with curved upper corners and moulded architraves. The ground floor features a plate glass shop front that cants inward towards the central shop doorway, alongside a stone house doorway at the right end, with painted rusticated pilasters. There is a late 19th to early 20th century cast-iron veranda of two bays, which is similar to the veranda in front of No 1 and No 114 Mostyn Street. This veranda has cast-iron columns with capitals, bulbous bases, and spandrils.
