The upper level of the meeting room takes up the largest space. The lower level, several steps down, forms an inviting nook in front and to the sides of the fireplace. The massive fireplace is centered on the south wall, opposite the entrance. Benches and bookshelves flank both sides of the fireplace. The two small rooms to the northeast and northwest of the central meeting room are used for storage and office space.
All floors are concrete.
The interior of this building has a highly unusual exposed roof structure of hammer beams supporting scissors trusses. The hammer beams rest on engaged stone piers built into the walls. The roof is the dominant architectural feature on both the interior and exterior. The steep pitches and shapes of the roofs, and the parapet walls all emphasize the extreme verticality of the structure. On the interior the verticality is reinforced by the exposed roof structure and the chimney that extends from the fireplace to the roof.
