The Stockbridge Town Hall is an asymmetrical two-story, red brick, hip-roof structure on a high cut stone foundation. The main facade has two octagonal corner towers, one turreted and a full story taller than the other one. In between is a shingled end-gable entrance pavilion with a broad, arched entrance approached by a staircase. The staircase is flanked by clapboarded sheds which cover stairs down to basement-level entrances. The side elevations both have a slightly projecting central gable containing a broad, round-head window, and flanking, smaller round-head windows.[2]
The interior contains two rooms in the basement used for township offices, and a larger open area used for meetings and voting. The basement also contains a furnace room, bathrooms, and a kitchen located in a former lobby. The upper floor is entirely filled with an auditorium, and its associated entrance hall. The auditorium is a square space with a stage at one end and a gallery above the entrance hall. The stage contains a c. 1910 painted roll curtain, depicting a scene on the shore of a mountain lake.[2]
