Terrace construction with different heights

Forget the first variant, nobody wants the cut edge in the middle of the terrace. The second variant is more like what looks better. Disadvantage, the narrow door would have a small step. How do you want to cover the terrace? The OP doesn't want that.

I don't want to cover it. The second variant also seems better to me.

Maybe the 3 cm could be bridged with a threshold ramp. They also come in 3 cm height. If the tiles are anthracite, it hardly shows..

They are very light but a small threshold already helps prevent toe fractures

On the website of „Rampenspezialist“ I even see these ramps in light gray..

There are still details missing from the Tuerausbildung.

How are the slabs going to be laid?
Gravel? Drain concrete?

I would lay on the left first without a slope up to the overhang, and from there on you lay with a 1.5% slope.

The water runs off through the joints, and where there is no slope it remains standing longer after rain, but then you take a squeegee and quickly pull it away if you plan to celebrate something on the terrace or so.
Mine are laid with 1.5%, but the slabs rise slightly at the outer edges anyway, so some water also remains on them.

I think all other ideas just don’t look good.

Or you start laying from the left with a slight slope and accept a small joint at the overhang by the window.
