I am not sure if this is a practical solution for your application but in the absence of floor insulation would underfloor heating be an option...?
I put in a Livella system a year back and it works a treat, easy to install, and you use as much or as little power as you want. Heats pretty quickly too. Can install after pouring or before. I put mine onto timber, for which it is safe, and on the top side was floor levelling compound.
https://livella.com/ I do not work for them or have anything do with them apart from using their product.
Installing a 25mm polystyrene layer of insulation to a floor in a room with no other firm plans to insulate the walls and roof will be a complete waste of time and money, what was needed at design stage was a costed and overall strategy to achieve specific insulation values and energy (Cost) savings, chopping and changing as you blindly move forward is going to plss your builder off and cost you more in the long run, develop a plan and stick to it is my advice! .
What I'm looking at in photos is two brick laid side by side on footings, I cant see where the insulation is going to go in a mortar gap between two brick?As it stands we have a hole in the ground waiting for concrete this is the time to insulate it and cheaply.
The walls can have their cavities insulated as they are built as the roof, all at a very low cost and little inconvenience it's a garage, not an airplane.
Any builder who finds that a problem should be left brewing tea (at home)
I think I may know what I'm talking about........... just

That was something I had planned with the original build, but was ruled out as we will e drilling into the concrete with installation of the 2 poster and what other machinery takes my fantasy
We put down underfloor heating in the conservatory and its lovely out there in the middle of winter
Are you serious? build a cavity wall c270mm wide on a foundation wall c200mm wide? the builder SHOULD be jobless and drinking tea at home giving serious consideration to that free adviceYour right there should be a cavity but a half-inch hangover should coupled with the existing mortar "bridge" cleared be enough to get some foil in.
It isn't perfect but it is where it is.
Another course of brick would easily give the room for some slab insulation, but it's not mine.
I have just seen a house nearby where there is a car lift to drop cars into the basement garage and there's room for around ten cars down there.
I did mention he needed a sump and a pump and got some unhappy looks, it needed some thought for things such as fuel leaks but should have been thought about earlier considering where it is.
There is some serious money being spent on building people's "castles" at the moment people are rethinking their homes.

We’ve recently moved into a house with underfloor electric heating in the conservatory. Seems to take ages to warm up, up to eight hours. How long does yours take from cold?
Well that's very interesting but, a standard brick width in the UK is 92mm not 70mm and a minimum cavity width of 40mm will still create a double overhang of some c25mm that if identified by the building inspector will result in a demolition order! Remember you said "I think I may know what I'm talking about." I think you need to return back to the drawing boardVery, it also acts as a drip, get the kettle on, this sort of thing
