Exposed concrete entrance platform manufacturing

...
We do have a 1m roof overhang and actually no precipitation there except drizzle, but would still create a 1% slope.
...

Be aware, with a 1% slope and additionally a broom finish—at worst even perpendicular to the slope—all the water will remain standing. Even with a 2% slope, puddle formation is not excluded.

Normally, you want a slope away from the house. To me, it now looks like you don't even need a podium. Just pave it right up, done.

Yes, yes, we want a single platform and no steps. Therefore, we would have to pave the driveway here sloping outward toward the green strip by 3.5-4 degrees. The paving should be roughly level with the green strip there, maybe 5 cm higher, so that soil does not always lie in the driveway. Past the front door, there is still a driveway leading to the garage at the back. This would then be about 2.8 m wide from the platform to the green strip. I would have the paving outside the platform run around it, sloping down diagonally to the front and back to reach the same height throughout the entire yard.

There is still a driveway behind the front door leading to the garage.
This would then be about 2.8m wide from the landing to the green strip.

That additionally argues against a landing.

When I look at the pictures, there is still a lot to be removed to create the landing.

Hi,
Why do you think so?
I only filled in there as a transition.
I don’t need to remove that much to be able to build the platform.

String height would be the top edge of the platform, the batten lies 20cm below on the left, so the bottom edge of the platform.

And from the top edge of the platform to the green strip on the left there is about a 45cm height difference.

Is this the former construction road, with us it was like this, with 8cm paving the path is now passable with 10t, Bulli, motorhome and similar
