4 Upper Clwyd Street

4 Upper Clwyd Street is a two-building group with 4A on the right and 4 on the left. The structure is a three-window range of one-and-a-half storeys, featuring a projecting cross-wing on the left with a half-hipped roof and a basement storey. It is built of red brick and topped with a slate roof, which includes a brick stack on the right and a ridge stack on the left at the junction with the cross-wing. A terraced walkway leads from the right to the entrances, with the lower part made of rubble stone and the upper part rebuilt in late 20th-century blockwork.

Number 4 is located in the advanced wing and has a shop in the basement storey, with living accommodation above. The entrance is on the right-hand return, accessible from the terraced walkway. This entrance features a wooden half-glazed porch at the angle of the main range and the cross-wing, which has a flat roof and replaces a sash window that was present in 1899. All windows are mid to late 20th-century two-light wooden casements with top-hung lights. The window above the porch is on the right-hand return, while the tall windows on the front include one at mid-level with a wedge lintel and another on the upper storey just below the half-hipped eaves. The basement storey has a boarded door on the left beneath a segmental brick head, and on the right, there is a late 20th-century shop front with a half-glazed wooden door, a shallow window to the right over wooden boarding, and a plain fascia. The west side of the cross-wing is roughcast. The gable end of the main range on the left features stone on the ground floor and roughcast above, with a three-light casement window offset to the left and a plain-glazed window above. The interior has not been seen.
