English: As seen in August 2021: the house and store at 516 Amherst Street, in the Black Rock section of Buffalo, New York, is a fine example (and was nominated as a local landmark in 2021 for that reason) of what's known locally as a "Buffalo double", a design that was a common element of the local housing stock and that speaks to the forward march of construction technology of the era of its construction (it was built in 1909), and specifically the newfangled technique of "balloon framing". This new method of wall construction, using long continuous framing members ("studs") to which flooring elements are appended, opened the door for large wall elements to be essentially mass-produced in a central factory, transported to the site, and assembled like puzzle pieces, making for a much faster construction process while still maintaining decent structural quality. A side effect of this was a relative uniformity in design, with simplified versions of popular styles of the time - Queen Anne in this case; Colonials, Craftsman, and American Foursquare variations would appear later - appearing side by side in essentially identical iterations. In commercial districts such as this stretch of Amherst Street, it was also common for Buffalo doubles to accommodate retail businesses on the ground floor, which this particular example did for many years. Records from April 1909 show the city's Bureau of Building issuing a permit to Thomas Marzynski for the construction of a "two-story frame store and house [and] also [a] barn in rear" at 516 Amherst Street, whose first retail tenant, apparently, was dry goods merchant Joseph Trudnowski, who remained at that location until moving down the street to 490 Amherst in 1912. Much longer tenured in the building was grocer Thomas Jakubowski, who opened up shop in 1923 and stayed through at least 1960 and possibly as late as 1971. The building is currently vacant but undergoing renovation.
