Description

This is a three-storey house and shop, built in the 18th century and located at 18 Main Street. The exterior is painted stucco with a close-eaved slate roof and brick end stacks topped with dentilled caps. The front of the building has three windows on each floor. The upper floor windows are sash windows with a square shape and a moulded sill. The first-floor windows are also sash windows with a moulded sill, but are larger in size. A raised pier is present on the left-hand side of the façade. The ground floor has been altered with a late 19th-century shopfront, featuring plate glass windows on either side of a half-glazed shop door. To the right of the shopfront is a house door. An overall fascia and cornice supports an iron balcony rail with scrollwork panels and a central panel that displays the name "Williams" in large letters. The shopfront incorporates outer pilasters, which are thinner at the door and fluted with a rosette detail in their frieze. Pairs of fretted brackets are positioned in the fascia above the outer pilasters. The four-panel house door is fitted with marginal glazing bars to the overlight. The ground floor currently contains a single, modernised shop.
