4 Highgate Terrace

4 Highgate Terrace is a group of four three-storey, one-window red brick cottages, accompanied by a two-storey, two-window former gaol at the right end. The cottages feature a renewed slate roof, boarded eaves, and modern brick chimney stacks, with a black painted plinth. They have small pane sash windows with voussoirs, including 15-pane windows on the second floor and 20-pane windows on the first and ground floors. The entrances have camber heads and boarded doors. Between cottages 3 and 4, there is a round arched entry to a tunnel passage, now fitted with a metal door and a plain fanlight.

The former gaol has an old slate roof with a brick stack and part slate hung sides. It features a 15-pane sash window on the first floor, a 20-pane window below, and a similar entrance. The left end is largely made of shale, rendered at the top where a door to a weaving loft has been blocked up. The right gable end is pebbledash, while the gaol's gable end is slate hung, and it has an attached boarded lean-to shed. A colourwashed passage leads to the shale rear elevation, which has brick dressings, cambered voussoirs, and modern casement windows. There are brick privy lean-tos for cottages 1 and 3, and a later one for cottage 4, along with small cellar windows and boarded loft openings concealing windows. The rear of the gaol is constructed of shale above rubble and features small pane metal frame windows.

The second floor of the building is open throughout and was used as a weaving loft. Cottages 2 and 3 have been combined into one house. The interior of the gaol still contains two cells with barred windows, where chartist rioters were held, and accommodation for policemen above.
