Hi all
I've attached a floor plan layout of the first floor of the build i'm planning. There IS going to be a top floor to this house. The room heights are:
ground floor: 3 metres high ceilings
first floor: 2.4 metres high ceiling
top floor: roof slope apples, min ceiling height 0.2 metres max height 3 metres
Here is the first floor:

So I guess the first floor on this house is going to be less than 4.5m and the top floor is more than 4.5 but less than 7.5 above ground level. My query is about 3 of the first floor rooms, which touch the wall that divides this dwelling from the other dwelling that makes it a semi. Because of the nature of the project, it is unlikely that any of these rooms will have an egress window. I think I can ensure that the stairway and hall is protected by making every door a fire door and the ground floor celings fire resistant, but is this the case?
The void on the left is a light well that spans all 3 floors, so the top floor and the hall on the first floor are mezzanine onto the ground floor :

The kitchen is open plan to the hall, and 2 exits are provided to the dining room. The light well/void has patio doors out to the garden so the building has 2 exits. The lounge has a set of folding doors to the outside too. study fitted with an egress window
My chief concern is for the fire regs of the rooms without windows; two of them are bedrooms. is it enough to protect the stair and hall, and maybe put a door between the two bedrooms?
Secondary, in terms of open plan kitchen areas, and the fact that next to the kitchen is a void/lightwell that goes right to the roof, should I be looking to glaze the void over to prevent the spread of smoke to upper floors?
