What is 'building control reportable' for a new doorway? I.e. is there a width below which you don't need to involve building control?
My daughter is turning a small adjacent bathroom into an en-suite and thus wants to make a new doorway between bedroom and [new] bathroom. It's not going to have a door in it but it will be about door size. It's in a brick wall which is part of the structure of the house, though it's internal, obviously!
While I'm about it how much involvement of building control would be involved in repositioning the WC which will require a new downpipe (we think)?
