Some commissioners echoed concerns about gentrification but ultimately approved the developer's plans, setting the stage for a film production studio on the Northwest Side.

AVONDALE — The developer behind The Fields project at the Logan Square and Avondale border won approval from a key city panel Thursday to redevelop part of its campus, setting the stage for a new film production studio on the Northwest Side even as some community members tried to block the decision.

The Chicago Plan Commission on Thursday approved New York-based developer Knickpoint Venture’s plans to add a 50-foot-tall building, two roof decks, more retail space and several sound stages for a planned film production studio to the 1.5 million-square-foot site at 4000 W. Diversey Ave.
