I think Yvonne meant rather to generally make the ground floor larger and plan living/dining/cooking/guest and reading/small bathroom/house technology there and then use a rather pitched gable roof with a 120 cm knee wall (22 to 25°) and accommodate sleeping/dressing/large bathroom in the standing area.
Yes, and as I said, the area is calculated according to net living area. That means, if I enlarge the area downstairs - let's say to 90 sqm or something like that, then I have an upper floor with a floor area of also 90 sqm - whether usable or not. And then I come to 180 sqm net living area. Contractually agreed are 135 sqm net living area.
I am unsure how it behaves if you insert a knee wall - so like a dry wall/additional wall on the roof side. Does what lies behind still count as net living area (I fear yes)? ... I'll ask about that...
Because you have given no information about the necessary pitch of the gable roof.
Yes, 35-55 degrees.
The planner house in the first post has 120 sqm living area.
Correct, because living area is lost in the upper floor due to the knee wall. As I said before, we originally planned a city villa or bungalow - nothing with a knee wall. Here, net living area was practically the same as living area. Because we did not get the original plot at the last minute (notary appointment was already scheduled and thus also the financing), we now had to redesign everything and try to stay within the framework of the existing financing and the contract.
Does the house have to be built so far forward near the street?
I assume so. It is like that for the neighboring buildings. In the statute, it is not specifically stated from my point of view, but rather "customary for the location" - and there all the houses stand very far forward, mostly directly on the path (without a fence or the fence is designed as an extension of the front house wall).
Is the shed at the end of the newly planned access road for the rear building going to be demolished?
Yes, that is a big residential/construction trailer. It will be removed.
It is really the case that if you want to deal SENSIBLY with a plan and idea, you need ALL information about the plot.
I understand that. It is also okay if no help is possible at the moment. As soon as I have any relevant information, I will share it with you. We don’t own the plot yet, no surveyor has been there etc. The notary appointment is in two weeks...
If I had known from the beginning that I would build with a knee wall, I would have done exactly as Yvonne suggested (larger area downstairs and only a few rooms upstairs). But I can ask again.
