Description

6 New Street is a two-storey building with a red brick front and slate roofs featuring bracket eaves. It has one rendered chimney stack and one slate-hung chimney stack. The building has brace plates at the ends and a plinth to No 5. The windows are 9 and 12-pane sash types with nearly flush frames and cambered voussoir heads. Notably, No 6 has a 20-pane bow window with a bracketed cornice, although the wall itself does not bow out below the window.

Access to the tunnel passage is through a round arched opening with an architrave, located between Nos 5 and 6. Inside the passage, there is a half-glazed door to No 5, and a similar door to No 6, both with panelled reveals. No 7 features a 6-panel door with a 4-pane fanlight.

The right end wall is rendered and has three-light windows under cambered heads, with a slate roof lean-to at the front end. The left gable end is slate hung. The rear of the building has been modernized with pebbledash and lean-tos on Nos 5 and 6, and there is a blocked doorway at the rear of the tunnel passage.
