Thorfun Posted December 1, 2023 Author Share Posted December 1, 2023 just to close this thread out..... I've heard back from the BCO and I am correct with my research. because we have a secondary exit from the basement and emergency windows/exits from the first floor we do not need protected stairways. as such we don't even need the doors between the hallway and kitchen. we might fit something in the future for sound reduction but nothing for now. it's one less thing to worry about. 3 Link to comment Share on other sites More sharing options...

I think you will find that you do need doors to the kitchen otherwise the bedrooms on the first floor become inner rooms from a kitchen which is not permitted.

I don't think they are inner rooms though? but as all first floor rooms have a secondary means of escape they're not considered inner rooms. that's my understanding 1 Link to comment Share on other sites More sharing options...

If you don't have doors to the kitchen - the hall and kitchen combined become the access room. Therefore all other rooms leading off the hallway and (by virtue that there are no doors to the kitchen) the kitchen are inner rooms. You can have an inner room accessed by the kitchen but only on the same floor the kitchen is on. The bedrooms are upstairs so don't comply. My thoughts anyway. APD: Inner rooms 2.11 An inner room is permitted when it is one of the following. a. A kitchen. b. A laundry or utility room. c. A dressing room. d. A bathroom, WC or shower room. e. Any room on a storey that is a maximum of 4.5m above ground level which is provided with an emergency escape window as described in paragraph 2.10. f. A gallery that complies with paragraph 2.15.

See Diagram 2.2. The lack of door requirements has come from the BCO from their technical department. So for our build it’s gospel and confirmed with the BCO and he’s going to put it in writing for me. 1 Link to comment Share on other sites More sharing options...

Good luck. 1 Link to comment Share on other sites More sharing options...
