It was designed by Louis P. Rogers of Thomas & Rogers of New York City.","why_significant":"The building is cited as one of only two important examples of cast-iron commercial architecture in the Inner Loop Multiple Resource Area. It uses cast iron to lighten the exterior wall, giving a largely glazed facade with a Venetian Gothic character. It is also tied to Rochester's patent medicine industry and to entrepreneur H. H. Warner.","narrative":"Rising seven stories on St. Paul Street in Rochester, this brick building was completed in 1883-84 as a laboratory and warehouse for patent medicine magnate Hulbert Harrington Warner. Louis P. Rogers of the New York firm Thomas & Rogers designed it, using cast-iron parts made by the J.B. & J.M. Cornell Foundry. The west facade combines pressed brick piers with cast-iron colonnettes, spandrels, and round and ogival arches, framing broad areas of glass. Compared with Rochester's Powers Building, where cast iron imitated carved stone, this design expresses the metal more openly to reduce the weight of the wall. Warner's remedies made him Rochester's wealthiest patent medicine entrepreneur before his empire collapsed in the 1890s. Later the building rented space to garment makers and a plumbing supply distributor. Some facade details were removed around 1950, and a large sign now obscures part of the front, yet the main cast-iron structure remains largely intact.","period_of_significance":null,"architect_builder":"Architect: Louis P.
