As a staunch Ilford film and paper user way over in the southwestern US, I've followed the process as closely as I could while HARMAN's landlord, LPC Living, tried and failed to have Cheshire East Council approve a redevelopment plan for its Mobberley site. The proposed approach would have moved HARMAN into much smaller facilities more appropriate for its current production volume, thereby minimizing overhead costs.
When the rejection happened last November, reports said LPC had 12 weeks (now expired) to file an appeal. I can turn up nothing since that indicates such an appeal was filed, whether LPC intends to submit revised plans or if it will just drop the whole idea. In the latter case, HARMAN would have 10 years remaining on its site lease during which, presumably, it will continue operating in oversized facilities. At the end of that time there's no clue what might happen.
This thread is to request that all you folks whose physical proximity to Mobberley makes doing so possible dig up whatever information on the project's status might not be readily available on line and then post it here. Thanks very much in advance for whatever detective work you can perform!
