Parkett joints installed untidily? Defect or tolerance?

Hello dear ones,

I am moving into my new building on 01.03. and have the handover with the builder on Monday.

The parquet was "included," meaning the builder had it installed. For 4 weeks now, it has been "gently" stressed, with stones, sand, dirt everywhere and thousands of scratches. I'm struggling to stay calm. Despite two warnings to the builder, the parquet was not covered. I covered it myself then. Yesterday, it was scrubbed with neutral cleaner by a "non-expert" person, as the gentleman himself said, naturally rubbing in the dust and dirt. My self-control is hanging by a thread.

Well - anyway, yesterday I also noticed that in some places it looks "uncleanly" worked on and some corners look a bit rubbed off. I am not a professional and don't know if this is normal.

I definitely don't want to be petty or exaggerate, so my expert question to you: is the result within a "normal" range or is it poorly executed?

A thousand thanks in advance!

Regards
Delilah

Should it be laid like this without offset? It looks strange.. Well, the joints.. No words

No is trash!!

I would never accept that like that...

I would never ever accept that - you can do better with a blindfold on. If I were you, I would be persistent about it - either completely new or at least 80% of the costs (?) waived.

Why is this a continuous joint and not an offset? Where is this joint located? Between two rooms? And in picture 2: there are two parallel joints visible? How many cm is that? What scale are we working with?
