The Tyringham Library occupies a prominent position in the small town center, at the western corner of Main and Jerusalem Roads. It is a single-story masonry structure, built out of rough-cut fieldstone and covered by a hip roof finished in terra cotta tiles. A large square fieldstone chimney rises from the roof peak. The main entrances are set in corner recesses, a stone post supporting the roof corners. A wooden entablature encircles the building below the roof line. The building interior is functionally divided so that one third now houses the post office, and the other two thirds house the library. The library retains many original finishes and furnishings, including a large fireplace, window seats, handmade oak shelving, and Mission style seating.
