ᐅ Are large vertical joints in the structural shell still acceptable, or do they count as defects?

Hello everyone,
In our house construction project managed by a general contractor, the masonry subcontractor was changed. The previous mason worked very neatly, but was replaced due to the slow pace of work (4 months for building the basement).
The new mason is now working very quickly, but in my opinion also quite roughly. In particular, I have noticed very large joints between the bricks. So my question to the experts is: Are these gaps in the masonry still within acceptable standards or even normal, or should we raise this issue directly with the mason or general contractor while the damage is still limited?
A few additional details:
- The building is a terraced house (row house)
- The walls are built with 36.5cm (14 inches) Poroton clay blocks
If I have forgotten any important information, please ask.
Thanks in advance for your assessment and support.

I believe this is already in the planning stage; it’s probably already reported in the Postillion.

However, I am not sure to what extent this might later cause a risk of thermal bridges and mold. (The remaining wall is 36.5cm (14.4 inches) unfilled Poroton).

Concrete plus external thermal insulation composite system (ETICS) has a different thermal transmittance than monolithic porous bricks.

He should just borrow a block saw. Using a starter course as usual at the bottom, he could have better adjusted the height, but the top is manageable now too. But not this amateurish patchwork. Are you seriously working with the “butcher’s general contractor” from @Hausbau0815 – honestly, what does that guy do for a living?
