This doesn't concern me personally, it's just something I wondered about after watching Property Ladder last night where they were forced to reintroduce a dividing wall between the kitchen and staircase because of 'fire regulations'
I've also seen mention on this programme along the lines of you must be able to get out of the bedrooms to the main door without passing through other habitable rooms.
Anyone have any ideas what the general jist of the building regs are in this area? As I say I'm not particularly interested in the full details as I'm not doing a development myself, just watching others on TV :-p
