any hard facts there?
When it comes to free advice, the burden of proof is usually reversed. I would have said just take it or leave it, but you yourself have already said that you’re not open to suggestions. So, anyway, good luck; it’s unlikely to collapse, just a house with construction defects among many others.

That doesn’t have to happen, but the risk is definitely there. Hopefully, there will still be enough money left to fix these mistakes later at a much higher cost. At least the total construction cost remains relatively low.

You can also get upset about more absurd things than whether someone adds a 2–4cm (1–1.5 inch) perimeter insulation or not... But to each their own.
