Description of the Historic Place
The Mainstreet Building is a two-storey, brick, Edwardian Classical Revival style commercial building located on the west side of Ladysmith’s main commercial street. The historic place is confined to the building footprint.
Heritage Value
Built in 1922, the Mainstreet Building is an excellent example of an Edwardian era Classical Revival style commercial building. The building’s symmetrical façade, pilasters, and highly decorative capitals are all typical elements of this style. The building also features exceptional multi-coloured, decorative brickwork.
The Mainstreet Building is part of a grouping of largely intact historic buildings in Ladysmith’s commercial core. Situated mid-block, the building is part of an almost continuous city block of similarly proportioned historic buildings that collectively create a cohesive streetscape.
The Mainstreet Building has been in continuous use as a commercial building since its construction. Although the building is among the youngest on this city block, it speaks to the ongoing commercial development of the area and contributes to the heritage character of the area.
Character-Defining Elements
The character-defining elements of the Mainstreet Building include:
- – all of the elements of the Classical Revival Style building as expressed in the simple form and massing, flat roof, symmetrical, three bay, multi-coloured brick façade, pilasters topped by large, decorative capitals, distinctive checkerboard brickwork below the simple cornice, contrasting colour brick quoining
around the second-storey windows, leaded glass in the upper sashes of the wood-framed secondstorey windows and the arrangement of the windows and doors at the street level - – continuous commercial use
- – the building’s location within a group of similarly proportioned commercial buildings on the town’s main commercial street
