The open interior plan of Village Hall is intended to reflect the transparency and accessibility of the municipal government. The lower level of the building contains the Police Department, including the lockup and a now defunct firing range. The elevated, triangular form of the Council Chamber is the dominant architectural feature. The two-story Council Chamber contains a semicircular conference table for Village Board members and raised built-in benches that can accommodate up to 200 citizens. The configuration of the benches places citizens no more than 19 feet from the Village Board president.
Village Hall is more than just a building, a fact underscored by its 2014 addition to the National Register of Historic Places nearly a decade ahead of schedule. Typically, buildings and properties are not eligible for inclusion on the venerable list until after at least 50 years. Village Hall's role in Oak Park’s efforts to achieve racial integration and community stabilization during the 1970s earned it special consideration.
The building has posed challenges to the many technological demands of modern government, but efforts have focused on working within the constraints of the design. Computer networks, television cameras for the Council Chamber and community room, and energy efficient lighting have been added. A geo-thermal heating and air conditioning system was installed in 2012 for the Council Chamber.
