Hi, I am trying to get my head around Building regulations and Building control, We are planning to add a door opeing in the NON load bearing wall between house and integrated garage, Bulding regulation say: door need to be FD30, 100mm difference between, and smoke seal and self closing mechanism, as per https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/485420/BR_PDF_AD_B1_2013.pdf page 30, As per Bulding contoll, Work that requires building regulation approval: Enlarging openings and removal of load-bearing walls requires Building Regulation consent. since this wall is not load bearing this work does not require bulding controll approval. Wondering if I miss anything, or things need to be considered?
