Costs partial basement vs. full basement

My architect believes that the partial basement does not need to be stepped, but I am very uncertain about it because I think that without stepping, it can easily lead to settlement cracks. Does anyone have experience with this other method of simply continuing or joining the floor slab?

My architect is of the opinion that the partial basement does not need to be stepped ...

Then I hope for him that he is well insured!

I am currently unsure whether the link is allowed to be used.

If one were to build a partial basement as shown in the picture below, would the disadvantages still be associated with it or does it look different with such a construction.

So only a basement on the right side, which has windows and doors on both sides.

In the picture, this is certainly not a partial basement. Otherwise, the same problems apply... because it remains a partial basement.

We planned a full basement The earthworks cost less than 4,000 euros The basement size is just under 80m²

May I ask what exactly is included in the earthworks? For us, this trade adds up to a whopping 20,000 EUR. Thanks and regards
