Description
25-27 High Street is a pair of shops with houses above, featuring a roughcast front with rusticated quoin strips and a slate roof that has roughcast end stacks on the front slope. The building stands three storeys high and has two windows, with No 27 being narrower. The windows in the middle and upper storeys have been replaced and are set within moulded architraves that include sill bands. The replacement windows in the upper storey are positioned lower than the original windows, which were located directly beneath the eaves.
The lower storey has shop fronts, with No 25 likely dating from the late 19th century. This shop front has fluted pilasters and a plain fascia that features a pediment above the central doorway. The replaced double half-lit doors are situated beneath a thin segmental arch, with the moulding continuing as nook shafts. The flanking windows are two-light with arched heads and thin turned mullions topped with capitals. The stallboard is boarded over. No 27 has a replaced half-lit door to the left under an overlight, and a plate glass window to the right, both set in original openings with moulded architraves. This building is part of a group that includes 25-27 High Street.
