Idea for staircase arrangement on the ground floor

Uhm, plot ratio of 0.15 on 700 m2? That doesn't match with a 11.5 x 9 m footprint, or do I have a knot in my brain??

Oops, 105 sqm may be built over with buildings (as far as I know, including garage)

Greetings

And unfortunately, we still don’t know what rooms there should be on the upper floor ;)

Guest bathroom with or without shower.

Really clear shell height 300 cm ... that means approx. 280 cm finished room height and approx. 320 cm floor height?

Yeah. The thing with the ceiling heights on the ground floor is like that.

Guest bathroom with shower

In the ground floor entrance area, I also want large closets to hide the clothes

In the kitchen there should be a U (with a counter in the room)
On the upper floor there should be a spacious bathroom and 3 similarly sized rooms (bedroom, child, work). The bathroom should be such that a washing machine can be placed there and laundry can be hung up

But you understood the floor area ratio, right? Have you already had a preliminary building inquiry regarding this? Did you overlook the floor area ratio? It looks like you have to change your plans Regards

I am reluctant to call this structure on paper a sketch, even though it might possibly fit the broader interpretation of the definition.

In our development plan, the site occupancy index refers to the main house. The site occupancy index may be exceeded for the garage and terrace. By 9 x 11.5, I mean the external dimensions of the house.
