Home Loan: Approved map, but property not built as per the map

Hi - I have identified a property and have done all the paperwork for the home loan etc. Have realized (very late) that there are a few modifications in the construction vs the map. (although approved)

Have already issued a cheque to the bank for processing etc. What chances do I stand to get the approval? (I may need to stop the cheque, if there's high uncertainity)

Thanks.
