a bit stuck with tiling

[White Room]

Why not use a timber threshold against the door rather than tiling it....

I think this is what I got, found something on the internet

the only difference is that when I look outside to the right of the doors I have a ventilation/air brick

so my DPC sag and does not have support, just don't know how to fix it

The floor screed should have been laid over the damp course....

I get this quite a lot on some new builds, I just cut the DPC away as there's no other way of doing it.
The level might be down slightly, build it up with some tile adhesive.

something like this ?

how thick it should be so it won't break ? would it be enough if I laid this on this uncovered area or do I need to laid it on the whole floor ?

The floor screed would have been 50mm and a thin roof slate would have laid over cavity, anything thin will crack with movement has as proved with your tile.

As said previous a wood threshold would be your best bet.

was looking now at this area and can't quite figure out how I would mount this wood threshold, the only way I can think of is to glue it to the DPC but this will move as well when you step on it.

what do you use to fill the gap? is there any risk once I cut of the DPC ( I mean in terms of damp etc ) ?

Drill, plug and screw into the bricks, before screwing use some quality Silicon into the hole to keep the damp proofing active.

whitebeam thank you for your suggestions today, will wait to see if others came across this issue and what was the solution, and will think through what I will do.
