It consists of two once-identical four-story brick factory buildings which face each other across Silver Street.

They are typical of Manchester's mill construction, with segmented-arch windows in a parade of bays on the long side.

The northern building has large ells extending to its north, giving it a modified U shape, while the southern one has two smaller additions.

A third building built for Hoyt stands further west, but is not included in the National Register listing because alterations made to it have compromised its historic integrity.

They were designed by industrial architect Augustus G. Stevens for Francis M. Hoyt, and, along with other nearby buildings, were the city's largest shoe manufactory.
