Is the variant of very high lift sliding door system statically feasible?

The two described variants were not offered to us by him. One can only speculate why - we will not find out.

Why, how come ... who doesn't ask, remains stupid (Sesame Street). It always takes two to make it a cheeky move not to explain something to a customer ...

, it would be nice if you could briefly show what you decided on, after all, quite a few people have put thought into it. :cool:

There is nothing to "show" since the house is still under construction. We decided on the version that is anchored in the building description and thus in the purchase contract. However, we have shifted the tilt-and-turn doors outward.
