Hartford Office Supply Company Building

One of several old factory buildings that survive on Capitol Avenue in Hartford is located at 376-400 Capitol Avenue, at the corner of Flower Street. The building was originally constructed around 1890 as part of the Pratt & Whitney Machine Tool Company, which already had factories across the Park River. The new building was part of the company’s Small Tool Division, which had its address at 285 Flower Street. The structure went through many alterations of the years and additions were made in 1899, 1902 (by Wilson & Bros. of Philadelphia) and 1916 (by Harris & Richards of Philadelphia). The building was later home to the Hartford Office Supply Company and is still known by that name. Plans in recent years to redevelop the vacant property for condominiums have not worked out and the building has been in foreclosure.
