43-45 South Street, Bo'Ness

43-45 South Street in Bo'Ness is a three-storey, two-bay flatted dwelling built around 1900, likely by James Thomson. It features shops on the ground floor and is part of an irregular terrace. The building is constructed from ashlar stone and has a ground floor entablature with a cornice that serves as the cill course for the first floor, along with a first-floor cornice, a second-floor cill course, and an eaves cornice. The windows above the ground floor are architraved and include stone mullions.

On the south elevation, there are two shops at ground level, each with outer banded pilasters topped with fluted capitals. The centre has a modern door, while the left shop retains a traditional two-part fixed display window with decorative astragalled top-lights. Each floor above features slightly advanced bays that create vertically emphasized panels. The first floor has tripartite windows beneath narrow decorative windowheads and flanking pilasters, while the second floor is reduced to bipartite windows that break the eaves into a raised blocking course, flanked by pilasters and further enhanced with full-height scrollwork detail.

The building has plate glass glazing in timber sash and case windows, grey slate roofing, and coped ashlar stacks. Square-section downpipes are fitted with decorative fixings.
