Elevation of garage location - interpretation of development plan

Hello everyone!

We have the following requirement in our development plan for outbuildings built on the property boundary:

The top edge of the raw floor must not be more than 30cm above reference point X (the height of the street at the boundary to the neighboring property). The average height of the garage must not exceed 3m above this raw floor top edge.

What exactly is the top edge of the raw floor of a garage? Is that, in the case of a strip foundation, the top height of the foundation?

The motivation behind this: the plot slopes downward to the north, the outbuilding must be located at the northern boundary of the plot. Due to the development plan requirement, the north side of the garage would therefore be at most 30cm above the street level. With a 6m wide garage and the slope of the plot, the southern end of the garage would then be below street level, which we wouldn't find so good.

Therefore the question: can we add 30cm of flooring on top of the raw floor edge of the garage, e.g., by added material or paving stones? The garage would then be only a maximum of 2.70m high.

Best regards!

I do not understand the problem, the requirements sound very reasonable (and I do not see why they should not be achievable). I interpret the width of the garage as irrelevant information until proven otherwise. You have not mentioned the terrain modeling as impossibly limiting. Therefore, from my point of view, the measurement point X on the neighbor-facing side with "street level" up to "street level + 30 cm" is given, and the limitation of the average wall height applies only to this wall side of the garage. Of course, only the garage itself has a raw floor; the top edge of its foundation does not count here. That will and can lie deeper by the thickness of the garage floor and is completely irrelevant here. I do not understand what is supposed to be achieved by fettling the finished floor of the garage.

With [...] the slope of the property, the southern end of the garage would thus be below street level, which we would not find so cool.

Coolness does not rule here, but who cares, i.e., what would be disturbing about that?

It would just be nice to design the driveway to the garage as ascending and not partially descending, that is our main concern, i.e. we would simply like to design the driveway so that the southern end of the garage is at street level, but then the upper edge of the floor on the northern side would not be +30cm, but rather +60cm.

Here is a small ugly sketch. We don't want to impair the neighbor nor to build the building higher overall; we only want to know whether, within these regulations, we can position the garage as shown on the right side of the image. Namely paved so that it gently slopes upwards from the street.

Hence the question of whether the top edge of the raw floor in the case of the garage is also the height at which everything inside the garage finally stands. In the actual house, they also distinguish between the top edge of the raw floor and the top edge of the finished floor.

Ugliness alone does not make a usable drawing. It is better to show a scaled plan view of the driveway with the actual heights, appropriately in the context of the overall situation.

That is why the question whether the top edge of the raw floor in the case of the garage is also the height at which everything in the garage will finally stand.

Yes, approximately: paved exactly like that, coated exactly like that, tiled about 2 cm, and tiled on screed about 5 cm higher.

Yes, roughly: paved exactly like that, coated exactly like that as well, tiled about 2 cm and tiled on screed about 5 cm higher.

Thank you for the feedback. Unfortunately, I do not currently know the real heights, only the plan values from the development plan.
