Lighting technology, Bauhaus, built-in spotlight, floor

Hello and good day,

we will start building in the autumn and are building in the Bauhaus style. We would like to install the same recessed spotlights throughout the house (to achieve the industrial look). Like those often found in large halls. Of course with LED technology. So not those small recessed spotlights with a 58mm diameter but large ones!

The question is how to implement this, should holes be planned directly into the concrete slab? This would save a lot of money because no suspended ceiling would be needed.

Which lamps should be used? How many watts? Lumen? Beam angles?

What technology makes it possible that if, for example, there are 5 lamps in the living room, not all of them turn on when one switch is turned on? Would 5 extra switches or 2 x 2 series switches be needed?

Also, we do not want to cover our cement screed with a traditional floor covering but would like something like an elephant skin? Do you know anything about that? This is also often seen in large fashion stores. It should not be a cement floor that needs to be skimmed. That is much too expensive for us... from 150 euros per m2 is rather expensive...

Thank you very much!

Ever talked to your electrician, structural engineer, architect? They can give you a lot of tips or need to be involved as well. You can, for example, sand and paint the screed. There are special "paints" for that. Alternatively, linoleum - which is also "in" again by now.

The question is how one should implement something like this now, planning holes directly into the concrete slab? Saves a lot of money, because no suspended ceiling is needed anymore.

I can imagine that the concrete plants will also charge for the holes. However, you could then also leave the ceiling raw, for example, leaving the joints open for the industrial design and not treating the concrete ceiling. But that would have to be taken into account in the planning phase, because the ceiling has to be ordered.

The question for me is whether one doesn't get tired of the industrial look at some point, especially if it is to affect all rooms. It's a bit cold, after all, to sleep between concrete ;)

With a suspended ceiling, you would be more flexible for the electrical planning, so you could decide on the locations of the outlets later.
