Magnuson, Charles, Three-Decker

Why it's listed
Built around 1912 at 56/58 Olga Avenue in Worcester, this three-decker sits at the eastern edge of the Belmont Street neighborhood, and its rear looks out on Green Hill Park. It reflects the final major wave of three-decker building in that part of the city. At the time, the area was dominated by Swedish, Swede-Finn and Finnish families, many of them skilled metal tradesmen employed at nearby American Steel and Wire or other metal fabricating firms. The first owner and occupant, Charles Magnuson, was a foreman at Worcester Metal Goods and lived here into the late 1920s, while early tenants included a machinist and a cabinet maker. Architecturally, the house has a side-hall plan, a gable roof, wood clapboard siding with shingled porch and bays, a three-tier porch on square posts, a three-story round bay, and bracketed cornice eaves. It remains unaltered and well preserved, which supports its local significance.
Significance in brief: It is associated with the last surge of 20th-century three-decker construction in the Belmont Street area, a mostly Scandinavian, working-class neighborhood. It is also an unusually well-preserved and well-detailed example of a popular local variation of Colonial Revival three-decker design. It is considered significant at the local level under criteria A and C.
