The district highlights the significance of the Union Mills (demolished) and includes an extensive collection of company-built housing erected during the 1840s and 1850s, as well as later non-company-built dwellings and institutional and commercial structures. The former include 16 single- and multi-family wood-frame residences built along Union, Kerry, and North Street. The majority are of a symmetrical duplex-style plan standing between one and two stories tall, however, several of the company’s earliest residential buildings, which were one-story houses with two-bay facades, can be found along Union Street. Many of the duplexes are of a vernacular design that persisted into the 1890s and houses built in the style can be found throughout both Union Village and in the housing developments built by the Cheney Bros. Co. nearby in South Manchester.
