It is a two-story rectangular structure, built out of ashlar granite stone in the Gothic Revival style.

Its main entrance faces north toward Florence Street, recessed in a Gothic-arch opening, above which are a pair of tall Gothic windows.

Smaller Gothic windows are elevated on either side of the entrance, with buttresses at the outer edge of the facade.

Its stained glass windows were provided by Wilbur Herbert Burnham, a frequent Cram collaborator.
