City villa floor plan 180m², basement, 3 children - Your opinions on this?

The office was planned from the top floor to the basement and we now have to make sure that the slight slope is used optimally. So much for the topic that we wouldn't be open to other opinions ;)

According to the architect, these are the guidelines: building envelope 10x10 for 2 full floors or 10x13 for staggered floors. So only 1 full floor may be built in the 10x13, but in the upper floor a full floor can again be added on 10x10.
We were advised either to extend the basement to 10x13 in order to build 10x13 with a staggered floor or to keep the basement and the building within the 10x10 building envelope.

Since I somehow don't understand the whole thing, and the basement is out of the question with 3 children and a slope anyway, I'll throw out a spontaneous idea: upper floor as children's floor, basement/lower floor as living space as parents' floor, so besides utility room and storage, office and bedroom plus small shower bathroom in the basement, in the upper floor the hobby room integrated with the children's rooms.
As long as the children need care at night, the hobby area can be temporarily used as a bedroom.

... Are the pipes located in your filigree ceiling? If I use round pipes, I would put them in the filigree ceiling and provide the openings right away to avoid later core drilling, chipping work, and the like.
Thanks for the tip about the Brady labels. Are those the self-laminating ones? ...

Well, you are quoting the text where it is stated ;)
The controlled residential ventilation pipes are located in the ground floor in the floor construction (25cm), in the upper floor the controlled residential ventilation pipes are located in the knee wall of the attic.
And yes, the Brady labels are self-laminating.

By the way, in my house construction thread there are pictures of the installed valves (from the outside).

Even if the pipes lie on top of the ceiling instead of inside it, you should provide the outlets before concreting (by installing a DN100 pipe). It is by far cleaner and easier than the ex-post core drilling.

Since I somehow don’t understand the whole thing, and the basement with 3 children and a slope is not up for discussion, I’ll throw out a spontaneous idea: upper floor as children's floor, basement/lower ground floor as living space as parents' floor, so besides utility room and storage, office and bedroom plus small shower bathroom in the lower ground floor, hobby room integrated with the children's rooms on the upper floor. As long as the children need care at night, use the hobby area as a temporary bedroom.

Thanks for the suggestion , we haven't thought about that direction at all and it might make sense. Only the small shower bathroom we would not move from the ground floor to the lower ground floor, because then we would need a lifting system again.

Those who can read clearly have an advantage ;) Thanks for the link, by the way, your house turned out very nice.

Even if the pipes lie on the ceiling instead of in it, you should plan the outlets before concreting (by installing a DN100 pipe). It is definitely cleaner and easier than the ex-post core drilling.

Yes, you’re right, as soon as the ventilation planning is completed, we will know where which pipes will go and then we can also plan the DN100 pipes before concreting. Thanks.
