Great stuff - in that case you're home in a boat! Good luck.

Double check it with your BCO. 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. ONLINE VERSION ONLINE VERSION ONLINE VERSION ONLINE VERSION 16 Approved Document B Volume 1, 2019 edition Building Regulations 2010 B1 2.12 A room accessed only via an inner room (an inner inner room) is acceptable when all of the following apply. a. It complies with paragraph 2.11. b. The access rooms each have a smoke alarm (see Section 1). c. None of the access rooms is a kitchen. TBE: Access rooms to inner rooms 2.7 A habitable room may be an access room to any inner room. A kitchen should not be an access room to an inner room other than – (a) to a utility room or conservatory which has an emergency egress window complying with paragraph 2.9; or (b) where the kitchen and the inner room are on the same storey and the kitchen is part of an alternative escape route leading to its own final exit. See Diagram 2.2.

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.

Oopps!

Have a look at Cedral cladding installation.

Have you got a section? Have you thought about an apex lintel?

You’d be better with a step in the facade. It will crack anyway so change the material to hung tiles or something.

Photographs please.

Why not put a lintel across the porch and build up in solid rendered rendered blockwork?

Again. Build it solid.

What a load of shit!

Do the whole width as a patio.

Why on earth are you building the sub-floor in cavity? Build it in solid blockwork to the underside of the slab. Use a stepped DPC no need for a 225mm gutter.

Then you need doors.

Doors in a two storey dwelling do not need self closers except a door between a garage and the dwelling. The doors from the kitchen to the hall can stay open 24/7 365 days of the year - they only have to exist.

Out two hatches in - one above the other. Bring down the ladder. Go up and open the insulated hatch.

Fire rating not required in a two storey house.

The rational for the doors is straight forward - they are there so that the bedrooms upstairs are not accessed through the kitchen. If the doors were not there the whole hallway, the staircase and the kitchen would be considered as a single space. Alternatively look at sliding doors or a Automist system. BC may allow you to install an Automist system in lieu of separating the kitchen from the staircase. I presume you have EEWs in all bedrooms on the first floor? and that this is only a two storey dwelling? Anything else and the requirements for means of escape get more onerous.

Posting this again.

Not a fan of cookers on islands - worried that someone could get badly burned.

For BCOs not needing to carry out any inspections if they don’t want to.

Please quote the legislation.
