Actually, just noticed you are doing an extension not a loft conversion. I had thought that the protected escape stuff only kicks in for 3 story houses (hence it being an issue for loft conversions). Do you already have a loft conversion and that's triggering the regs in the kitchen work, or is it needed for kitchen extension now as well?
Not sure if it'd be counted as a 3 story. It has 3 floors, but steps from the street up to the front door and step down to a lower ground floor (which is where this kitchen is). So both ground and lower ground have direct access to outside...
