The main facade consists of a pair of projecting gabled sections flanking a central entrance portico.

The interior is organized with the librarian's desk at the center, and reading rooms in the flanking wings, with fireplaces at the end walls.

Its dominant architectural features are the roof supports, which are formed out of massive curved timbers.

In 1912, a dedicated library building was built at 158 Portsmouth Avenue, to a design by Charles Howard Walker.

The 1912 building now serves as a research library and meeting place for the Stratham Historical Society.
