Discuss with your engineer. It could be fine with a strip footing. (S)he should be able to give ball park costs for the options.

The timber frame co should be able to give you a full set of drawings and calcs on request.

The floor often holds the walls together.

If you are using local authority building control, get the building inspector to visit and they are likely to have experience of foundation types where you are. If piles are needed they may also suggest piling contractors.

Is this a reduced level dig for a raft or for strip foundations?

I think you have answered your own question and if you are happy without one, that is fine. I use one all the time for roasts, baking, stir fry, even veg boiling. I have taken out the fan unit and just use the lights on the canopy plus ducting to an external extractor mounted in a plant room, so there is no motor noise.

Looks good. What is the floor finish?

There will need to be rodding access as well. Maybe ask building control to pop round, or email them?

I would think a gun was among the most prized things for a criminal to steal and the danger in having one turned against you would probably outweigh any protection it offered.

Flood risk is covered by planning consent, not building regulations. On your planning consent there may have been a condition stating that the work will be carried out according to the plans and details submitted. It is this that would bind you to do as proposed. If you want to change it you should go back to the planners. If there is no condition you do not need to worry.

It would be the screed not thick or strong enough and / or the load from the kitchen units not spread far enough.

When you tile this, it is not essential to cut around everything as accurately as @Onoff as the WC pan will cover all the holes easily. You could just do one big cutout. If, however, you leave a gap at the top of the flush pipe the pan will not cover it and you will cry.

The new connection looks the best option. Make sure the chamber is either foul or combined (not surface water). You will need to contact Building Control. You can cap of the existing pipe inside.

If you use the 40mm ones you may not hit your fingers quite so much!

Perhaps invite him over to install a few...

Why are they all concealed hangers? They tend to only get used at the end of trimmers etc.

You can load out a beam and block floor that has where you just brush in a lean mix grout. The concrete would give added strength but you should be OK. The supplier should advise on max loadings. I have seen one fail but they had staked blocks 2 packs high x 2 along one beam and the floor had not been grouted.

Who on earth parks a car in a garage? A wet one even madder! Garages are used for storing crap you are not allowed to bring into the house.

OK. After he has reduced levels and installed a French drain, if the floor is still damp I suggest a sheet of DPM and a chipboard floor over. Cheap and you get a smooth dry surface.

I think the OP has already got the garage in place...

Yes they were. Not terrible amounts of rust but enough to be noticeable and only on the handles. Letterplates, glass surrounds and escutcheons were fine. We have loads of exterior stainless steel elsewhere on the project and none of that has been a problem. RK blamed lack of maintenance on the part of the owners an cited the presence of cobwebs as evidence. Their MD did them no favours with customer service. Here is a close up of a handle which I removed to clean up:

No first hit on google and they seem to have technical info and prices online, so work out what you want and possibly shop around. It is only glass, not magic.

I had 8 RK Doors fitted in a development. £3,600 each including fitting. They had motorised locks and were a special design to match the planning drawings. Quite expensive but they seem decent quality. There is no snib, so if the door shuts behind you and you don't have a key, you are stuffed.

Certainly noticed with Velfac and IdealCombi but I think it could be generally, as the max sizes are at the limit of the system.

Have a look at https://www.balustradeglass.co.uk/product/glass-juliette-balcony/, decide what you need, then shop around for prices. Simplest is fixing to brickwork / blockwork but you can also fix to timber frame or even the door frame.
