Internal planning of multi-storey flats

When multi-storey flats do not have their own external entrance at ground level, adopt one of the following approaches. a. Approach 1 – provide at least one alternative exit from each habitable room that is not on the entrance storey of the flat (Diagram 3.5 and paragraph 3.22). b. Approach 2 – provide at least one alternative exit from each storey that is not the entrance storey of the flat. All habitable rooms should have direct access to a protected landing (Diagram 3.6 and paragraph 3.22). c. Approach 3 – provide a protected stairway plus a sprinkler system in accordance with Appendix E and provide smoke alarms in accordance with BS 5839-6. d. Approach 4 – if the vertical distance between the entrance storey of the flat and any of the storeys above or below does not exceed 7.5m, provide all of the following. i. A protected stairway. ii. Additional smoke alarms in all habitable rooms. iii. A heat alarm in any kitchen
