The building is a two-story masonry structure, built out of red brick, with terra cotta trim and a slate hip roof.

It is five bays wide and three deep, with ground-floor windows set in round-arch openings capped by terra cotta keystones.

The main entrance, located at the center of the Grove Street facade, has an elaborate surround, with engaged columns rising to an entablature and shallow balcony with iron railing.

[4] The building was constructed in 1912 to a design by Henry Francis, at the time one of Fitchburg's leading architects.

The building is one of the city's finest examples of Georgian Revival architecture, and has been relatively little-altered during the society's ownership.
