So what now: visible screed cheap or expensive?

You probably save the production of a separate visible surface or covering when making exposed masonry or exposed screed. But for that, what is usually hidden must also be done in Sunday-fine surface quality, which costs time and thus wages. I don't really see any big savings lurking there. Such a "loft floor" is also rather something for purists. When applied over the entire surface in all rooms, it overwhelms you. Therefore, I think it is not an alternative insofar as you will not want to apply it consistently over the entire area (meaning: all rooms). The only thing that comes onto my plaster is WLAN

And can a "simple" craftsman do that? Or should specialists be sought?

From my point of view, clearly: yes. For everything that is not routine solutions, it is worth asking for special references. But a non-specialized provider can also meticulously approach a masterpiece, while a specialist with peak orders employs inexperienced personnel and rushes over it carelessly.

You don't save anything because the special screed also has very special prices. I learned from neighbors that they have this screed and are unhappy: you can see every stain, grease apparently penetrates, moisture, everything is very crumbly. However, I don't know to what extent they had it sealed.

Don't you save time at least?

Acquaintances of ours also have exposed screed and love it. It's very uncomplicated, and the children even ride Bobby Cars on it.

If it is now comparably expensive to a good tile or floorboard, it would definitely be an option for us.

We have now inquired with the general contractor and are curious.

Presumably coated, as is not uncommon in garages or workshops (?)

Definitely. It shines and from time to time it has to be cleaned with a care mixture.

Uncoated screed, even if smoothed, is sensitive to coffee, etc... And plant oil also causes stains.

Therefore, coat it. Epoxy resin is partly questionable due to emissions.

For 2k PU floor coating, you usually have to expect >120 euros/sqm, or it looks like in a warehouse. You can also get nice 90x90 tiles installed there.
