Vinyl installation direction and cutting-off problem

Hello everyone,

I have been pondering the following problem for a while. For better understanding, I am attaching a floor plan image showing three rooms, their exterior windows, and the door openings. Vinyl flooring is to be installed in this area, with plank dimensions of 152 x 23 cm.
1. Option: Kitchen laying direction lengthwise
Since the flooring should be laid lengthwise to the main light source, it would probably be appropriate to lay it lengthwise toward the large window in the kitchen. However, this creates the problem that with a room length of 464 cm, there is a leftover of 6 cm (including a 1 cm expansion gap). Even if you start not with a whole plank but with a half or otherwise shortened plank, the joints shift only by 6 cm per row. That is far from ideal. I also want to keep the waste as low as possible.
2. Option: Kitchen laying direction crosswise
OK, there is another window (or balcony door) in the kitchen, so possibly laying crosswise? The width of the room at 297 cm is almost perfect for the plank length of 152 cm. However, this creates another problem: Since the adjacent corridors are also to be laid with the same vinyl, they would have to be laid in Längsrichtung so that there is no 90° rotation at the door thresholds. For long, narrow rooms like a corridor, this is certainly not desirable.
How would you approach this?

Thanks in advance,
Regards

the bumps per row only shift by 6 cm. That is anything but nice. I also want to keep the waste as low as possible.

What a question - you start with a third or quarter board and that's it, you throw away the 6 cm anyway. How many euros are you worrying about saving here? 5.. or 6€?

You obviously didn't understand me. The 6 cm are not overlapping at the end of the row - they are missing! And no matter how you start, with a half, third, quarter or eighth plank - the joints shift only 6 cm each row! Except (and that's what I meant by a lot of waste), if you start each row with a different fraction of a plank so to speak "anew". But then you don't just throw away what's left at the end of each row, but also what you cut off at the beginning of the next one to maintain the spacing of the joints. The waste is immense.

No, I think you didn’t understand me either. If you start with, for example, one third, then at the end you have 2/3 minus 6 cm left, which you place at the front again, and so on. Eventually, a short piece is left, which you throw away and start again with one third.

No, I think you really didn’t understand me. If I do it the way you say, then the joints (or transverse joints or whatever they are called) in each row are only offset by 6cm. But the manufacturer specifies 30cm or something in that range. Do you know what I mean?

try to recreate that with paper strips... But you have to start asymmetrically. Don't cut off exactly half.
