Description
42 High Street is a two-storey building with a mix of architectural features. It has three windows for No 40 and two windows for Nos 41 and 42. The fronts of Nos 40 and 41 are finished in scribed cement render, while No 42 has painted pebbledash. The plinths are made of rubble, brick, and weatherboarding. The roofs are covered with renewed slate, and there are wide boarded eaves along with red brick chimney stacks, with a modern addition at the rear of No 42. Notably, No 42 is slightly set back from Nos 40 and 41.
The windows are small pane sash types with flush frames, featuring 12 panes on the first floor and 16 panes on the ground floor. There is a 9-pane window above the low carriage entry between Nos 40 and 41, which has a square head at the front and a segmental arch at the rear. The doors are six-panel designs, with No 42 having a part-glazed door. The left gable end of No 42 is slate hung.
Inside, the passage has a rubble base and is weatherboarded up to half its height, indicating the original depth of the building, while the rear part is fully walled with rubble. A modern two-storey extension has been added at the rear of No 40 to replace a brick cottage. The rest of the rear features rubble with brick dressings. Nos 41 and 42 have three windows, with lean-to and modern casement windows for No 41, and some small pane metal frame casement windows for No 42, which also has a lean-to porch.
The room above the passage in No 40 shows signs of earlier roof pitches and a blocked opening. The older timberwork is made of oak, while the later work is in pine. No 41 features an 18th-century roof with overlapping purlins, and the central truss was once a partition. A handrail sweeps up to the top with a balustrade, and there are timber frame partitions on the ground floor. No 42 has stop-chamfered beams.
