The Cromwell Community Board has agreed to redevelop the facility, when funding is available, and residents have until July 29 to air their views.
Board chairman Neil Gillespie said various funding options would be explored.
"We had to try and work out what we wanted to happen with the building and sought feedback from the community about that and now we've developed this option for the upgrade, taking that into consideration, and want to hear back what people think of it," he said.
The board first considered upgrading the hall in the late 1990s and revived the idea two years ago because of declining use of the facility.
The building had few windows and its facilities no longer met building code requirements or the public's expectations for a venue of its size and stature, the report said.
The first phase of development is estimated to cost about $3 million. It includes a redesigned entry foyer, enlarged ticket booths, revamped bathrooms and a rebuild of the lean-to structures at the side and front of the main hall. The kitchen and supper room would be upgraded and the main hall auditorium enhanced.
The building would also be rewired.
The second phase, costing about $1.1 million, includes a pavilion with views of the lake.
At this stage, the board has approved only the first stage. The project will be included in the council's long-term plan next year and the public will have another chance to comment.
