This is in the Inventory of Heritage Properties as 570 King Street West. The ground floor addition on this building was added in 1983. The Toronto Silverplate Building is architecturally significant for its orientation and design that distinguish it from other factories in the area. Historically, the building is notable as one of the earliest surviving factory complexes in King-Spadina. It contributes contextually to the character of the King-Spadina neighbourhood as it evolved from a residential to an industrial district at the end of the 19th century. The heritage attributes of the building are found on the exterior walls and roof with attention focused on the principal (south) façade and side (east and west) walls. The structure is clad with red brick and trimmed with brick and stone. It rises 3½ stories under a gable roof with brick end chimneys (the chimneys have been altered). The central hipped roof ventilator has been removed, but its brick base remains. With its rectangular plan, the building is oriented so that the long wall forms the principal façade. It is organized into 11 bays with a central three-bay frontispiece beneath a gable with a trio of round-arched window openings. Along this elevation, segmental-arched window openings with brick voussoirs are placed in the lower two stories, while flat-headed window openings with lintels and sills light the third floor. The single-storey flat-roofed addition that conceals the first floor is not included in the Reasons for Listing. The pattern of the fenestration is repeated on the east and west walls.
