Description
The building now occupied by the National Westminster Bank is a three-storey structure with a basement, featuring a slate roof and brick chimneys, constructed from local rubblestone masonry. The front of the building is six windows wide with overhanging bracketed eaves.
On the second floor of No 11, there are three 12-pane horned sash windows, arranged with four panes over eight, positioned close to the eaves. The first floor originally had three 16-pane horned sash windows, but the left window now contains larger panes. The central doorway on the ground floor is flanked by broad three-part horned sashes with large panes, all set under cambered arches. The entrance features a panelled door with a semicircular fanlight above, deeply set in a round arched doorway. There is also an inserted window in the gable end facing west. Both the gable end and the front of the building show signs that the roof has been raised.
No 9, which houses the National Westminster Bank, was originally paired with No 11 but was extended at ground floor level towards the street in 1903. This single-storey extension consists of four bays made from bullnose local stone. It has a doorway to the right and three windows to the left, all under segmental arches with a stringcourse above. The left window lacks the stringcourse. The windows feature stone sills and modern glazing, with an entablature above and a low parapet to the flat roof. A flagpole is also present, and large pane sash windows are arranged similarly to those of No 11.
