Own work - power cable through multi-service house entry

Correct. Surface-mounted installation in the new building is actually unsightly, but in the utility room where a thousand pipes are visible anyway, it should be less disturbing.
Thank you

But may I ask why this is classified as "Pfusch"? Does it have any impact on the screed?

But may I ask why this is considered "botched"? Does it affect the screed?

No, not the screed but the cable. No impact protection present and take a look at the multi-conduit entry.

Explain to me how the supply lines come out of the entry? Flush-mounted?

How do you come to the conclusion that there is no gas connection?

Reading others' answers and giving sensible answers yourself isn't really your thing, is it? You always prefer to scribble unfinished half-sentences [emoji106]

If you read my post again, there is no assumption in it.

True, but maybe I missed something or you know more.

Or do you have a better idea

Surface-mounted in the cable duct. Or flush-mounted... in any case on the wall.

Under the screed, you'll have more trouble than joy later on. Apart from the technical defects ("botch job"), the loop from the floor into the multi-utility entry would remain a dirty corner.
