Have you worked out the airflow?
Those airbricks are roughly 1500mm2 each. Says you need 500mm2/m2 in your spec.
I agree with above about the insulation. Mine didn't come down below DPC! I did put a 25mm PIR upstand internally.
No UFH? If you want a liquid screed you could go to 55mm screed and bump up the floor insulation a bit...

The extension is 5.8x6m. 1500mm2 opening per metre run of perimeter needs a lot more air bricks than what's done so far! Isn't that 6 across the width or 3 double and the same on each side?
You can get airbricks with much higher rates that are the same size. The plastic ones are about 6500mm2 according to the screwfix website...
Depends how big the void is between floorboards and ground level in your house? I would probably core cut through.
If not just knock the airbrick down further in the outer skin. The air will find a way...
