Rough planning exterior - elevation relationships

Oh please tell me more. Do you still have proper foundations under the slabs? What dimensions do all the supports have? And the distance between them? Are they lying loose or somehow fixed? You laid the floorboards parallel to the house, right? Was there a specific reason for that? The general recommendation is rather away from the house. Do you have a slope? What are the experiences with heavy rain?

The forum section seems a bit empty here. Or is there simply nothing to say because everyone would do it the same way?
I didn't have as much participation as expected in a floor plan thread, but I did have two to three comments...

I'm missing the question or your concern or problem.

I am missing the question or your concern or problem

I need to learn not to always hide these in so much continuous text...

Here I would be interested in your experiences and whether I am significantly forgetting or doing something wrong.

whether the positioning of the cistern, for example, is okay like this or if something else would be more sensible.

whether the heights should be modeled differently somehow

Access road is to be paved with grass grids (are 5 cm buildup enough? Or is more soil needed over the gravel/RC).

Well, I somehow miss the future garden planning. You write something about a garden shed, paths… where is your garden drawing with colored pencils? This graphical drawing confuses me and isn’t homogeneous at all :) If you have to lay the provisional construction road, then what are our experiences for? Lay it, use the gravel, or plan something else where it is now, like a secondary terrace, garden shed, or something like that. Or am I misunderstanding your problem? We had the driveway made by the garden landscaper. Correcting height differences works best on the property itself while digging. Smaller height differences are best corrected with beds. Larger ones on paths with two steps. … and if I’ve answered off-topic now, that’s not a problem either ;)

No, it was about identifying other obvious mistakes that I don't recognize due to lack of experience. If no one sees anything, then that's good. Yes, this is not a garden plan. For us, it's initially just the excavator who takes care of the rough stuff right away. The details can come later.

There are no foundations under the slabs. What do you mean by "What were the dimensions of the beams"?

We laid the floorboards parallel to the house because, in our opinion, that harmonizes better with the external blinds – so purely an aesthetic decision. Causes zero problems. There is no slope. What should happen in heavy rain? There are enough gaps anyway, or what do you mean by that?
