Pouring leveling compound in the garage for parquet installation

Hello everyone,

I want to convert my garage into a music room (for my grand piano and so on) and also lay parquet flooring in there. However, the garage has a slope towards the drain in the middle (max. 40 mm). There is also underfloor heating installed in the garage (it is under the same roof as the rest of the house). My idea is to pour leveling compound in there. That should be suitable in terms of load capacity. Only:
1. can this be removed relatively easily again (in case the garage might be used as a garage again)? By relatively easily I mean a demolition hammer is okay, but not hammering for 3 weeks, rather that it might be possible to knock everything out again in one or two days without going too deep (underfloor heating)?
2. Will the underfloor heating still provide sufficient heat after the slope has been filled with leveling compound?

Thanks for your thoughts.

Are you allowed to convert the garage into living space?

I wondered that too.
At least you are not allowed to have a living room on the boundary development, but that does not seem to be the case if the garage is connected to the house with the roof?
That is also definite.

However, you still have to apply for a usage permit. As far as I know.

Regarding the question: in my understanding, compensation material should bond with the substrate ... it would then of course be difficult to separate it again.

yes, I am allowed to renovate the garage. Permission has been granted.

there are now different types of leveling compound; maybe someone knows of a compound that is load-bearing but does not adhere "infinitely" strongly, so that it can be (I repeat) removed "relatively" easily. Wouldn't screed be suitable for that?

Screed and dry screed then floor covering The screed is loose and then everything can be easily removed again.

No idea how the whole thing works with underfloor heating

I didn't notice that at all. How wonderful!
