Ground floor plan city villa 230 sqm

What story height are you thinking of? Keep in mind that the story height also includes floor construction and ceiling. Story height <> clear room height!!!

The story height given in the example drawing results in about 250 cm clear room height .. depending on floor construction and ceiling thickness.

House in this design planned as 13m x 11.5m. A maximum of 150sqm may be built over, which we want to fully utilize. [...] Maximum heights/limitations: 9m height [...] repeatedly "improved"

The garage belongs to the floor area ratio I >> the house is too large. An attic conversion will be completely unrealistic with a roof pitch that complies with the height limit, especially with a hipped roof. Show the planning before the "improvements."

Staircase to the left of AZ1, so practically above the (too short) stairs.

You are really stretching my imagination right now. Mind you, with over forty years of experience in floor plan design.

But it doesn’t have to be, if a smarter room layout results,

The first step toward that would be a needs-oriented planning of the rooms "instead of" the division of a (furthermore incorrectly dimensioned) maximum floor area.

I just want to focus on the floor plan here.

Then please be realistic and focus on realistic dimensions, where, for example, you can use a toilet or a room is also spatially nice. For example, what do you want to convert in the roof if you are only allowed to build up to 9 meters high?

It just happened that way,

Try to plan and design, not just draw what happens. And it would be quite good if the ground floor carries the walls and roof of the upper floor. Also here there are some tips for house and room orientations. If you had spent today in this house, not a single one of the 6 hours of sunshine would have reached your living area, except the bedroom and bathroom. And for an open and modern design, you should also plan windows according to the room size. The terrace (not the garage …, I am pretty sure about that because of my house, but not 100%… and there are also development plans that explicitly change something from what the state building code allows) belongs in the floor area ratio I. That means you definitely have to build smaller (no matter who of us is right). And since I am already somewhat confused on this topic: You hardly know your way around, don’t know how high a floor is or will be (see attic conversion and stairs), and here I simply advise you to find an architect or a construction supervisor who can roughly offer you something. Then we can still continue here.

Show the planning before the "improvements"

Since these are only our plans so far, they will certainly not be better.

You are really stretching my imagination. Mind you, after over forty years of experience in floor plan design.

At least from terraced houses, I know it this way. The stairs from the ground floor to the upper floor and from the upper floor to the attic are "stacked".

Thanks for the link, I will take a look at it. That’s exactly what it’s about for me, to have improvement potentials in our planning pointed out so that we can present our contractor with a concrete and viable idea and he does not plan past it.

And for an open and modern design, you should also plan windows according to the room size.

I did say walls and windows can still be moved. The windows currently serve as placeholders. (The same applies, by the way, to the wardrobes in the children’s room. These have not been purchased yet and of course can also be placed elsewhere...)

That means you definitely have to build smaller (no matter who of us is right)

The terrace may additionally take up a maximum of 30 sqm, so I do NOT have to build smaller. Since I was only referring to the floor plan, I did not mention this separately.

I simply advise you to find an architect or a structural engineer who can roughly offer you something.

We already have a structural engineer but want to approach him with a concrete and viable idea — and for this I appreciate input from you because you have the experience, I don’t — so that we can save a few planning rounds.

Then we can still see further here.

Then we can gladly close it at this point, and I might come by again with the engineer’s draft. I simply assumed it’s better to drop by here in the forum around 11:30 and not just before 12, since the planning is still open in all directions now.

Thank you very much for your input so far; I will definitely take with me to change the staircase. This definitely has consequences for the floor plan.

The bathtub can also be omitted, or shift the wall a bit, we are still not happy with the arrangement.

We actually like it very much, that's why the small hallway, because we consciously do not want it in the hallway.

Staircase left of AZ1, so basically above the (too short) stairs.

I understand completely, but our financial situation has improved, I just want to focus on the floor plan here.

Important for us for the family traveling a long way, but the spatial separation for a longer visit is simply very important to us. Additionally, the option of renting out.

The family lives farther away, ok. For us, 200 km and 450 km for both parents. When they come, you haven’t seen them in a long time and then you want to 'kick them out'? Hmm, I don’t quite understand that. Wouldn’t a guest room of 15-18 sqm be sufficient?

And renting out the granny flat on a 500 sqm plot? Then I might as well buy a condominium. The privacy would be exactly the same...

It's somehow the typical building style in Germany. Above all, big. One should also know that the rooms should be tidy and lived in. What will you do if, for example, there is no second child? Then you have a soda room. Better smaller and pay more attention to quality.

Your staircase drawings in the floor plan do not take into account the space requirements of a quarter-turn staircase. You must plan at least 130 cm for the landing and also at least 330-350 cm in length.

Of course, wardrobes and similar items have not been purchased yet, but when designing floor plans, you also consider possible furnishings and include them... so that you can see whether a room has a harmonious layout. For children's rooms, for example, I always plan with 140 cm wide beds... almost every teenager I know wants this bed size. Of course, they do not need this bed size at the age of 2... but the room should be able to accommodate it.
