Floating parquet was unintentionally installed with a pattern

It would definitely have made sense here to work with a bit more waste and place the joint exactly in the middle. Although, if one plank is enough, couldn't you have just worked without a cross joint?

Apart from that, the expansion joint at the wall seems really, really small to me; many have no gap at all. Floating parquet floors expand and contract much more than laminate, I noticed, especially with high humidity in summer...

Such a shame about the parquet. I took a long time in every room and sometimes calculated 3 or 4 variants of how to lay it so that the joints are always at the same height, even if I have niches or floor-to-ceiling windows. As Tolentino already says... if you actually have 3 packages left and not two left hands, then take everything up again and lay it anew with the joint in the middle.

I would definitely forgo baseboards here for a year. The edges need to be reworked; it will 100% warp...

Engineered parquet has tongue and groove. Not only at the front and back but also on the sides. If you start with a whole plank and the leftover piece, it always gets smaller. He even worked with more waste so that it looks good. Otherwise, you would have 3 pieces per row with a leftover of maybe 10 cm.

It's hard to explain. I installed it the same way as you have it and am satisfied with it.

What stands out more to me is the color difference of the first 2 parquet rows. I would have complained about that. It has somewhat of a reddish sheen if the pictures are not deceiving. But it could also be due to the lighting.

Finished parquet flooring has tongue and groove. Not only at the front and back but also on the sides. When you start with a whole plank and the leftover piece gets smaller and smaller.

Lay whole plank, throw away leftover piece. Take whole plank, cut to size, click in along the entire length, throw away leftover piece, etc. They definitely saved money in the wrong place, and it shows now.

If this is going to be a dressing room, furniture will be added - then it probably won't be as noticeable and will be less of an issue over time. Good that it’s not another room.

That only stands out because you made red marks. You won’t even look at it later.

Why didn’t he apply a wild bandage? I thought you ordered it.

Was it probably an apprentice working on it? It also looks like a pass? Sooner or later a stylish runner will go on it, right? Anyway: I also think it will fade away. You will still enjoy your house. Compensation or something, I don't think there's anything to be done about it. One could consider if you still have an area where the rest could be laid, e.g., on a wall, hip-high or something. For example in the wardrobe. They could do that for you cost-neutral as compensation.
