useable/useful floor space

Where on earth did you find that "term"? It not only makes no sense as a translation of "useful floor area", it doesn't even seem to be correct French!

But what about (
espace par terre utile)

Once again, you seem to have a fundamental problem here: one cannot translate 'floor' in an INdoor context with 'terre', which inevitably connotes 'land', 'ground' 'soil', 'earth' — all very much OUTdoor things.

If it is about indoor it would be better to translate also into espace par terre utile .

I suggest that you look again at your source for "terrain superficie utile" and check how you parsed it. "superficie utile" is, indeed, a French collocation (though not relevant here), but "terrain superficie utile" is not. Try analysing the parts of speech (nouns and adjectives in this case). I also thoroughly agree with Tony's comment to you, below.

Absolutely not! 'terrain' (outdoor, land) has nothing to do with 'floor area' (indoor space) — that would bpossibly be the "official" term for something quite different. If you wish to make these wild assertions, you might at least provide references to back them up!

terme officiel en France c'est terrain superficie utile.

You need to be very careful here, as the way these are measured / expressed differs between FR and EN, so you have to watch out you don't either misrepresent something, or end up with a counter sense.
There has been a lot of previous discussion on KudoZ, I think probably mainly in FR > EN, and it would no doubt be useful to research that, especially the highly knowledgeable contributions by former contributor "Bourth"
I think the abbreviation SHON was one of the trms I recall, with any luck, that may prove a starting point for you to research other related terms.
