The Des Moines Community Playhouse has announced that it has raised $3.4 million in its $10 million campaign to expand and renovate the theater. The Playhouse’s fast-paced growth over the last few years is spurring the overhaul, which will include a new lobby, streamlined public spaces, a revitalized mainstage theater, more parking, a new education wing, additional storage for costumes and properties, new dressing rooms, updated mechanics and green rooms that can double as classrooms. So far, the biggest donations include $500,000 from Bankers Trust Co. and the Ruan Family Foundation, $350,000 from Prairie Meadows Racetrack and Casino and $300,000 from Principal Financial Group Inc. Construction on the first phase is expected to begin this summer.
