We definitely want to have the parents on the same level as us. It's just nice to open the terrace on Sunday morning

and spend a few unplanned and extra minutes with them.

Uh... that's already a contradiction: next door on the same level // a few minutes. What you are planning there is constant being on top of each other. For breakfast, you can also walk a few steps around the corner and spend the rest of the time in private. Privacy has never harmed anyone, not even a big family.

Since you haven't filled out a questionnaire yet: how old are you? Children? How old are the parents?

Questionnaire? I will probably find it through the search. The parents are 71, the children 11, soon 4 and the 3. The little one is coming in July. I am 42, my wife 33. We have equity of about one-third of the project volume. But I don’t yet know how much I want to use.

We have enough alternatives with the large garden in the west, the small one in the south, and the terrace in the attic.

Just now the information came that we have been approved for both our hipped roof and the additional piece for the driveway. This way we get the opportunity to build the driveway with a length of 35 - 40 m and thus make up height well.

Please, please, please, not the next hip roof :confused: It’s like a plague :rolleyes:

the additional piece for the driveway. This gives us the opportunity to build the driveway to a length of 35 - 40 m

You are really wasting your floor area ratio here – and at the same time wondering about comparisons with *LOL*

I’m buying it especially for the driveway. Besides, it’s essential that the house is standing upstairs. Otherwise, I’d have to remove half a mountain or build a bunker. I haven’t read Rick’s post yet, I just didn’t know him.
