Framing - Gap Between Slab Edge and Frame

There is a step down in garage slab. The framing stands on the stepped down slab on two sides. One side it is flush to the slab edge. However, the in the second side there is a gap of around 40mm between slab and frame base, as it appears in the photo. I guess, the framer has done this deliberately to get the room size correct. If it is flush, the room next to garage (pantry and powder room in this case) would get reduced by around 40mm.

I asked the framer about this gap. He told that the gap later will get filled up by some concrete or something. Has anybody come accross a similar situation? Is it a concern? would they really fill? thanks.

When we built our last house, we had a step down to the garage as well.
The slab was slightly out which ended up the same as yours. That was 20 years ago and we had no problems at all with the house at all and you wouldn't have even known.
Ours was never filled.

Mine is exactly like yours. Currently under construction.
I worry about lots of things.. However this issue doesn't bother me at all.
The frame is sitting firmly on the garage slab hence I have no concern.
The gap will be "filled" by the plasterboard and skirting board.

We have no gap, and the slab lines up perfectly. But our slab guys were meticulous with their measurements, as they had a couple of boxes of beer riding on it...

That being said, it's nothing to worry about if it's not a load bearing wall
