Exit from house to garden - Please provide design suggestions and photos

Some already know that one of our mistakes in building the house was assuming that "floor-to-ceiling" patio doors would be flush with the floor or exit. :) Smarter forum members know that this is not the case, and now I know it too. ;-) We equated "floor-to-ceiling" with "threshold-free" due to lack of expertise.

Now to my question: How can we design the exit from the house/room to the outside nicely, practically, and in a way that is "gentle on the house"? We have decided against a dirt layer/dirt border made of gravel and, if possible, would like to lay terrace slabs around the house so that an approximately 80-100 cm wide path is created around the house and we can comfortably step into the garden from every ground-floor room.

One unpleasant thing is, among other things, that the "patio door sills" (see photos) protrude too far.
- Should we leave them as they are and how could a nice solution still be created?
- Should we shorten them a bit so that they align with the "reveal" (?) and do not protrude or should we remove them entirely?
- Can we remove them without problems and replace them with "patio door sills" made of the same material as the terrace pathway slabs?
- Is a grate directly at the house wall (prefabricated house in timber frame construction) absolutely necessary?
- Should we simply use the protruding "patio door sills" as a step? According to the house manufacturer, they may be stepped on and loaded.

Since I am not so good at abstract thinking, I would be grateful if you could possibly explain your suggestions with photos.

Below are two photos of the actual condition:

dear , unfortunately I have to tell you that at my only floor-to-ceiling window it looks exactly the same. BUT: This windowsill will not be suitable as a stepping surface, just like mine, on the contrary. If you step on it, the underlying 1st (that is the windowsill) and 2nd water-carrying layer (the glued sealing membrane) are likely to be damaged in the medium term. We have dealt intensively with this exact issue because there were massive mistakes made here on the upper floor by the balcony and stair builder. A stepping-stable level (grating or support for ceramic/concrete slabs) would have to be installed over the windowsill, which in all probability is hardly feasible anymore due to the insufficient build-up height between the windowsill and the bottom edge of the floor-to-ceiling window. Because this detail would have to be addressed BEFORE implementation. Everything, of course, as always only my humble layman's opinion. But if anyone here has better experiences or tips, I would be interested in those too ;-)

what just occurred to me: Aren't the upstands missing on the right and left sides of the windowsill that prevent water from running into the insulation layer? Or are they completely plastered over? We photographed all these details during the construction phase on the recommendation of our shell builder to be sure that it was implemented correctly (sometimes you can't see it later).

Thank you for the note. I will check or research this with my husband tomorrow.

As a supplement ;-)
There is still a floor-to-ceiling door leading to the terrace, where, in addition to the second water-carrying level that came from the painter/plasterer, an ultra-sturdy several mm thick elephant skin was later applied by the roofer; moreover, underneath there is no wood fiber insulation as everywhere else but XPS (as perimeter insulation). A flush exit is of course planned there. I didn’t want that at the floor-to-ceiling window at all ...

Smarter forum members know that this is not the case and now I know it too. ;-) We equated "bodentief" and "schwellenlos" due to lack of expertise.

Smarter forum members would have used a search term like "schwellenlos" or "Flachschwelle" as an option and spared themselves and the rest of the world from letting the countless individual threads of yours become even more uncontrollable. Here it would have fit as a continuation to mention:

(a shot, a hit – I really didn’t search for long, and you yourself could have done that too!)
