Hello everyone,
I want to level the floor in a room (living room/open kitchen) of about 35m² because it is very uneven and has a slope. I marked the reference height from the hallway floor and transferred it to the living room using a leveling laser. The result can be seen in the sketch. There are height differences between 8mm and 60mm.

Part of the floor is a ribbed slab (built around 1900) and the other part (extension mid-70s) is a hollow block ceiling. On the ribbed slab, there is 2cm screed/2cm Styrofoam with some kind of solid fill underneath; this area also gives way a little at the edges. The house has a full basement.

Since leveling compound is extremely expensive and I need to keep costs under control, I am looking for alternatives.
At first, my idea was to cover the entire floor with 25mm OSB boards on a wooden battens. However, I had to discard this idea because some spots deviate only 15mm from the reference height. I also know there are dry screed systems on dry or bound fill, but they build up too high.
I am now considering whether to remove the floor from the old building (2cm screed/2cm Styrofoam) and then simply apply self-leveling screed bonded to the entire floor surface.
Is my idea reasonable? Do I need to worry about the statics? Or are there other alternatives?
In the end, the floor does not necessarily have to be 100% flush with the hallway floor, but it should be level so, for example, cabinets etc. do not stand crooked :)
The final covering is planned to be click vinyl or adhesive vinyl.
