And I have seen much worse with the mortar pockets
Me too, yes, here it is a very mild case (both in extent and in frequency).
We fully trust our architect and the executing company
I think, quite rightfully so. It is harmless for the stability, the locally different thermal transmittance is not dramatic, and otherwise it looks very solid. If it’s going to be the house from your avatar picture, I will probably even like it
Otherwise, I haven’t seen much of it so far, only the stairs and the open roof soffits you had mentioned or shown.
