Wall structure 36.5 Poroton T8 including clinker

I had back then a 30 Poroton W10, then insulation, then an air gap, and then facing brick.

Today it is a 36.5 T9 with plaster

A 50 cm wall is nothing special. 42.5 cm block plus exterior plaster, you’re also almost at 50.

But 45 is not almost 50 ;) .
Base plaster is usually 15-20mm, top coat 3-5mm. Possibly an additional reinforcing layer.

Thank you very much for the hints, we will now probably switch to 36.5 Poroton + insulation + clinker

Which hints did you misinterpret in such a way as to now consider this agreed nonsense?
That would automatically lead to thick fortress walls: with the insulation, including finger gaps / air layers, we will hardly be talking about less than ten centimeters, at the same time this rules out the option of facing bricks which costs another nine centimeters, and with insulation on top even the 36.5 cm structural shell thickness is exaggerated. What exact structure does the general contractor recommend?

Nonsense or unnecessary. What is the purpose of this? 17.5 calcium silicate brick + insulation + clinker would be better then. Or 36.5 + clinker slips

sorry - that was indeed nonsense. I obviously meant

24cm masonry
12cm mineral facade insulation with fleece
1cm air layer
11.5cm facing bricks
