Electrical installation, joint, filigree ceiling

Hello first of all,

this is my first post, I hope I’m doing everything right

We are currently planning our house, we would like a filigree ceiling, possibly as exposed concrete (depends on whether we like it or not) Our plan is to place the cables for the ceiling lights (surface-mounted spotlights, not recessed lights) along the joint lines of the ceiling (see pendant light in the picture). Is it possible to make the cable outlets exactly in these joints or does this pose a problem?
Or what needs to be considered in this regard?

Thank you very much in advance

I do not understand the problem. The cable is not laid from below in the joint or even a slot made in the ceiling, but on the unfinished floor on the floor above and then drilled down at any point (or also from below upwards so that nothing breaks out).

Yes, it should not be a problem

Ok, thanks, so I don't have to install any boxes or lay conduits in the ceiling before pouring?

only if you plan to replace the line at some point

Well, it never hurts to possibly have reserves for the future. KNX is going into the house anyway. But think first.
