The lady has realized that the garage should not be converted into "my" room where I can have a Chesterton armchair, my books, a humidor, etc. Instead, we will place the bedroom there.
Now the question is how to start this:
- How do I handle the edge where the garage door goes down? There's a (partially) rusted iron angle there that will end up under the wall that will close off the outward wall. Can I place the wall on this, or could there be problems? It’s also not entirely even since part of the iron angle is missing and part of the concrete is missing.
If you're wondering, I've dug up in front of the future wall and current door. I was thinking of just laying gravel there. Opinions on this, please.
Should one cast? Is sill insulation enough? Could there be moisture migration when I lay underfloor heating? What is moisture migration? The questions are piling up, and I am grateful for any help I can get with this project.

Some not entirely easy questions to answer, we weren't told everything.
But I assume you will have regular indoor heating since it will be living space, so the floor needs to be insulated a bit if it's not already insulated under the slab.
If you don't have insulation under the slab, a solution must be placed on top. The next problem is that your slab will likely "draw up" moisture from the ground, so both building materials and insulation must be mold-resistant, foam plastic, steel studs, and such. Another solution might be ventilated flooring with ventilation between the slab and insulation+flooring.
All these solutions build on the height, if this is not acceptable, I think you might have to chisel out the slab if you don't want the floor to be too cold.
I'm not particularly sure about all these constructions, but this is how my thoughts go regarding your problem.
My recommended course of action is this:
1. Find out if the floor is already insulated under the slab.
2. If not, consider how much it's acceptable to raise the floor.
3. Then think about which solution suits best; if you can't put a lot of insulation underneath, floor heating might not be suitable.
Also, keep in mind that it might require a building permit to change a garage into living space.

Sorry that I wasn't clearer about the conditions.
The slab is not insulated. Digging out and insulating is not an option (trust me). Therefore, I assume it will be necessary to lay, as you mentioned, Nivell, Platon or similar. A 15 cm elevation of the floor is possible.
Will I be okay if I lay the mentioned Platon/Nivell> underfloor heating> self-leveling compound> wood flooring?

We are working on similar projects. I can't quite see how it looks in the pictures... We had a construction company remove the garage doors, cast up with reinforcement up to the level at the gate itself. (i.e., I recommend removing the rusty iron angle). Then a leca wall was built. We rented a good concrete grinder and ground the entire floor, then leveled the whole floor with leveling compound (floor spackle). After that, we insulated the entire room internally, and have now reached the flooring. We have chosen Japegolv, which is a mechanically ventilated floor. This also creates a negative pressure in the room, which is very good when insulating internally. Since we do not have an insulated concrete slab, we are laying 3 cm S 200 foam on the spacer mat. (www.jape.se). It builds up a total of about 7 cm in height. Moisture migration is due to the concrete, which consists of small microscopic air holes, causing capillary suction of the moisture under the concrete. The moisture needs to be removed, hence a mechanically ventilated floor is preferable.
