It was designated a National Historic Landmark in 2000 as an exceptionally well-preserved "second period" colonial-style meeting house.

The building is a large two-story timber-frame structure, with a side-gable roof, clapboard siding, and a granite foundation.

The main (south-facing) facade is five bays wide, with a symmetrical but slightly irregular placement of windows around the center entry.

Enclosed two-story gable-roofed stairwell ells extend from the each side of the building, with a similarly decorated south-facing entrance.

The main entrance opens into a central hallway, through a floor filled with box pews to the pulpit area, which features the original sounding board.

[6][7] A Meeting House Association was formed in 1911 through the efforts of Professor Franklin Hooper, director of the Museum of the Brooklyn Institute.

It is an extremely well-preserved example of a "second period" colonial meeting house, in which the principal entrance was on the long wall.
