Floor plan assistance: 216 sqm single-family house with granny flat & double garage

I don't understand the purpose behind this floor plan...
An apartment is supposed to be accommodated in the attic? Where are the kitchen, bedrooms, etc.?
And where would the home office room for working be?

Only change the labeling of the rooms ;) see picture. A typical apartment from the section. Even the height in the middle can add a very special flair.

You probably don't have any proper plots or they are unaffordable?

Something like 800-1100m2 where you can really develop yourself?

On your first plan, there is a utility room under the roof. Where has it disappeared to in the other floor plans?

Overall, I think this simply isn't the right house for a granny flat. Especially not with 2 staircases. You’re not doing yourselves any favors with that, and I wonder why it has to be like that at all costs. Maybe the house is simply not suitable for you and your ideas in the end.

Take the advice of and , then it can turn out well.

Still wondering if this is really meant seriously here. 216 sqm living space. for well over 800k including additional costs and then living and dining on 44 sqm while there is still a staircase in the living area and, because the room is already so spacious, also a kitchen with an island. HUH? Room height of 2.44 and 2.48m. Who is this being built for? Surely not for oneself, or do you really want to live like this? At least you don’t have to get up from the couch to cook anymore.

Just change the labeling of the rooms ;) see picture. From the layout, a typical apartment. Even the height in the middle can add a very special flair.

"Special flair" is realtor speak for apartments that can just barely be considered living space with good intentions.

there probably aren't any proper plots of land with you or they're unaffordable?

Something like 800-1100m2 where you can really spread out?

Yes, but then the price is reasonable only with considerable aircraft noise from Frankfurt Airport or you have to add another zero to the price.
