Plus €12,500 net for a 9.6 kWp photovoltaic system financed separately
Only small regional companies recommended by other builders are being considered.
So far, the following trades have been contracted:
Earthworks: €20,000
Shell construction: €73,000 + €1,000 for the porch above the front door, Wienerberger Poroton T9
Roof: €19,000 + €1,500 scaffolding
Electrical work: €11,000 excluding chiseling work
Window materials: 17 Salamander triple-glazed units + Beck & Heun roller shutters + 5 Selt exterior blinds = €16,000

How do you plan to simulate the Poroton blocks? They provide almost no vertical insulation value. Without sufficiently deep base insulation extending up to 0.8 m (2.6 ft) below ground level, you will definitely have problems in the corners. There’s really no need to simulate that.
Your target of 1200 €/m² with a lot of own work is admirable, but if such small issues aren’t solved properly by a planner right from the start, there will probably be more to come. You also seem to be somewhat resistant to criticism, like “oh, that won’t matter anyway.” It’s better to take the advice seriously and see how the situation can still be properly fixed.

Saying it’s wrong might be a bit harsh – it’s better to let the bricks extend beyond the slab so the insulation can be applied flush with the wall.
If you stick the insulation on the outside now, the ground level must be 10...20 cm (4...8 inches) above the top edge of the slab (raw floor) to be able to cover the insulation.
Due to rain, I would always set the slab slightly above the ground level. I just can’t imagine it.
If the first row of bricks stands over the slab and then the wall and the slab are insulated, it won’t be flush.
You could understand it better with a drawing.

Does it look like that in your case?
Do you want to fill up to the finished floor level or just slightly above the insulation? I haven’t fully understood that yet…
If the wall protrudes or a narrower base stone is used, the insulation can be brought flush up to the second row of bricks.

Your target of 1200€/m2 (about $111/sq ft) with a lot of self-made work is respectable, but if such small details at the very beginning are not solved by a planner, there will probably be more issues to come. You also seem somewhat resistant to criticism, like “oh, that doesn’t matter anyway.” It’s better to take the advice seriously and see how it can still be properly fixed. Using a program to simulate thermal bridges?! That’s exactly what they’re for.
I admit I’m fairly resistant to criticism. I’m happy to accept input and then independently assess how serious the issue is.
That’s why I changed my mind about the blocks.
Especially with advice from the internet, where 99% of people are just so-called “experts,” things are usually not as bad as they are made out to be.
So far, this approach has usually worked well to above-average success.
I planned this here using monolithic masonry:
The other option would certainly have been more advantageous, but my impression is that most houses are built as shown above, so it can’t be that bad.
The reveal position has already been corrected:

Does it look like this for you?

If the wall protrudes or a narrower base block is used, the insulation can be installed flush up to the second row of blocks.
Thanks very much for the drawing, now it clicked.
If the insulation on the floor slab wasn’t there (red cross), then a thermal bridge would form as shown in blue?
The wall is already insulated horizontally because of the hollow spaces in the blocks. But the floor slab is not insulated.
