The current Italianate meeting house was constructed in 1867–68, and is an important surviving design of Portland architect George M. Harding.

It is a tall single-story wood-frame structure, with a gabled roof, an exterior sheathed in clapboard and flushboarded siding, and a granite foundation.

The entry consists of a pair of doorways, each flanked by thin composite columns and set in round-arch openings.

A larger three-part round-arch window stands above them, with a banded frieze along the raking gable edge of the vestibule.

The tower has four stages, and is elaborately decorated, with an open belfry and an octagonal spire.
