ᐅ Planning a Double Garage with Boundary Construction, 6x9 meters

Good morning everyone,
we are currently working on the planning of our garage.
It will be a solidly built garage and extension measuring 6x9 m (20x30 ft).
The zoning plan requires a green roof.
We are now facing the "problem" that our plot is sloped according to the terrain survey points.
In reality, it looks to us as if parts of the area were already excavated during site development. In the rear section (see marking), you can see the likely original "natural" ground level.
Because of the survey points, we are not allowed to build our garage higher than shown in the attached plan, relative to the natural ground level.
In addition, the green roof requires a thicker roof construction, which reduces the interior ceiling height. The design includes a concrete slab with tapered insulation plus green roof.
An electrically operated sectional door from Hörmann (model LPU42) is planned.
Looking at the installation dimensions, I see considerable difficulties in implementing this reasonably with the current design.
The marked door corresponds to the module size. However, the electrically operated version requires a minimum ceiling height of 2,235 mm (7 ft 4 in). With this design, ours is 2,125 mm (6 ft 11.7 in).
If I am reading this correctly, the maximum door we can install at our ceiling height would be the one marked in orange. This would result in a clear door height of 1,775 mm (5 ft 10 in). I really do not want to have to bend down to enter my garage.
Perhaps someone here has faced a similar issue and can share their experience.
Are there any options to get approval to build the garage a bit higher?

And where is the height restriction stated now? That was the point, right?Most likely in the state building code… for what is not mentioned in the zoning plan, there are no other regulations.

So where is the height restriction mentioned? That was the main issue, right? The main problem, especially with modified terrain, is usually the height limit for the garage at the property boundary, which is typically 3.00 m (10 feet) on average (in some regional building regulations also maximum façade heights), measured from the original ground level. If height is then “used up” by not converting the garage into a retention basin—and if a green roof is “added” on top—this can become tight. Worst case scenario ;-) you might have to operate the gate manually to avoid having to account for the height of an automatic gate opener as well.

I think I would try to exclude the green roof from the height measurement and only specify the concrete slab. Then just indicate a few flowers with soil on top and submit it like that. If they reject it because of 20cm (8 inches), you can always pretend you didn’t know and apply for an exception. Otherwise, try a different route...

They have already planned with the maximum. The concrete ceiling could still be replaced by a wooden beam ceiling. However, this would only save a few centimeters (inches). How should a green roof (i.e., additional load) be supported less heavily using wooden beams than with concrete? I consider that a misconception.
