The Newtown Public Building and Site Commission is holding a special meeting tonight in executive session to interview firms for the Newtown High School auditorium renovation.  Newtown residents approved $3.6 million for renovations during a July 6th town meeting.  Part of the project cost could be reimbursed by the state.  The project calls for making it handicap accessible, up to code and adding state of the art features.  It's not slated to begin until early next year.
