What is your specific question or what is your problem?

What is your specific question or what is your problem?

Is the interior plaster layer included in the 49 bricklayer standard wall thickness? Actually not, right?

Is the interior plaster layer included in the 49 mason measure wall thickness?
Actually not, right

Yes, the construction drawings show the raw construction dimensions without plaster. Your energy consultant is absolutely correct with his statement.

Because the exterior wall construction would be
17.5 cm aerated concrete, 10, 8 cm insulation, 2 cm air layer, and 11.5 cm clinker, but then we would come to 51 cm and the architect said that it does not fit because he has 49 in the drawing. He said we would then have to make the entire floor plan as an exterior wall to 51.
We certainly will not do that.

17.5 + 10 + 8 + 2 + 11.5 = 49

You are writing exactly how the 49cm come about and nowhere in the list is plaster mentioned. I also do not understand the question: Does the architect say that he needs fixed interior dimensions and therefore all walls should be moved outwards? Or why not build exactly like that, then apply the plaster inside and avoid strange calculations?

It seems to me that the topic is very emotional. Perhaps you have some time in a moment of calm to describe the problem a little more closely?
