Started my kitchen renovation, removed existing cabinets , found a section of the ceiling with some exposure to the roof . I want to patch this ( ceiling and side wall ) up before installing new cabinets . How do I do this , haven’t done any thing like this before , so seeking guidance . There is a level difference between the sections ( where the cornice ends ). The size of the ceiling section is 1.3m by 60cm . These areas will be covered up anyway by the cabinets so not looking to have a clean finish . See pictures attached
