Did you seriously fail to see the forest for the trees, i.e., got so caught up tweaking other little screws that you forgot that a garage has an unheated and therefore often thinner floor?
Yes, I absolutely didn't have that on my radar. It's my first and probably only house, and as a layperson in the field, one tends to focus on other things.
I don't even understand a word of that (???)
We don't want anyone to be able to walk into the garden on the right side of the house. Actually, we had originally thought of a wall with an access gate for a mini excavator there. The suggestion with the mini excavator came up somewhere here in the forum, and I liked that. The architect kept saying we don't need to draw that; I can just do it later. The building consultant then said that everything has to be planned beforehand if we want to avoid a second building application. Furthermore, he pointed out that it could get very tight on the right side of the house, especially since there is a steep slope at the property boundary there.
Passing on this information, the architect took another look and also concluded that the access on the right won't work. Therefore, as an alternative, he recommended a rear garage door for the mini excavator to pass through. He dismissed my concerns about whether the garage would be tall enough by saying that the mini excavator’s operator cabin can be removed and that would not be a problem.
Nevertheless, the sealing off on the right will be included because we want a 2-meter-high fence there, and he says only 1.80 meters can be built later without approval.
