Floor plan for 200 sqm city villa - Are wishes achievable?

Hello everyone,

I am a bit overwhelmed with our floor plan or keep running into the same problems... The main issue is probably how to integrate a straight staircase from the ground floor (EG) to the upper floor (OG) or how we would need to change/extend the hallway to fit such a staircase in without "destroying" the other rooms.

Who is responsible for the planning:
- Variant 1: planner from a construction company (not yet an architect)
- Variant 2: do-it-yourself

What do you particularly like? Why?
The floor plan is basically good and has been largely implemented according to our ideas.
What do you not like? Why?
We would prefer a straight staircase. According to a staircase calculation site, this would have a length of 3.70 m.
After research, this might be rather uncomfortable and therefore unrealistic.
If necessary, we would also extend the hallway for the straight staircase.
Symmetry, especially in the front view of the house, is important to us; therefore, we would like to keep the type of door.
The angled part in the upper hallway is not particularly nice. (Bedroom/office)
Furthermore, the hallway window was placed in the toddler's room; this will be removed again so that there is light in the hallway of the upper floor.
I am also wondering if the chimney flue in the upper floor can still be freely routed, possibly with some offset in the ceiling/floor. Or does it have to run straight up from the fireplace in the ground floor? Then it would end up in the middle of the upper floor hallway.

If you have to do without, which details/extensions
-can you do without: I am open to suggestions for now
-can you not do without: ideally the straight staircase

What makes it particularly good or bad in your eyes?
See differences between our design and that of the construction company
- straight staircase instead of a quarter-turn
- kitchen set back
- window in the hallway instead of toddler’s room
- ideally no obstruction of the hallway in the upper floor

Your floor plans do not match.
Why 2 dining areas?
Why the bay window?
Why the huge bathroom on the ground floor?
Why the basement?

The house seems oversized in many places. As if you don’t know what to do with the space.
A staircase with 3.7 meters straight does not work. It has to be 4 meters. The entrance is one example.
Door opens and you almost fall down the basement stairs. For that, you have a 9 sqm guest bathroom—for whom or what?

How big is your budget?

...

We would like a small dining area for everyday use and a large one for guests. We are the center of our family; celebrations are usually hosted at our place.

Edit: The dining area in the kitchen is just a bench with a small table.

The bay window is meant to loosen up the rather large house a bit and we like the look of it.

We currently live in just under 160 sqm (apartment) and also had a large apartment before; we are reluctant to downsize.

The guest bathroom could have been smaller for me as well. However, my husband wants it a bit bigger. Among other things, a large cat litter box will go in there.

The basement will have a fitness room, a storage room, the utility room, and a hobby/second office.

The current plan from the builder is about €550,000 for the house including the basement.

What exactly do you mean about the stairs?
The basement stairs would start at the living room door; hopefully, you can't fall down them from the front door.

Yes, I have also doubted this stair calculation, but I don't understand how it can comply with all DIN standards and still basically not work.

The main problem is probably integrating a straight staircase from the ground floor to the upper floor, or how we would have to change/extend the hallway so that we can fit such a staircase in without "ruining" the other rooms.

Why are you taking on this problem at all? - even with a comparatively minor redesign like simply straightening the spiral of the stair’s starting point, you inevitably intervene so significantly in a floor plan that it won’t be resolved with just minor adjustments. Implement changes right from the start on the basis of a design that matches the requirements in such essential points - otherwise, that is not a fortunate foundation. If the straightness of the staircase is so essential to you, then you should communicate this to the planner of the construction company accordingly.

We actually communicated this that way as well, but it wasn't implemented. Maybe because it wasn’t possible due to different ideas. The quarter-turn staircase only slightly blocks the hallway because you walk directly toward a wall of the concrete staircase, and the staircase isn’t exactly age-appropriate either. A straight staircase would visually be less obstructive and would later allow for a lift. So your statement more or less means: 1) Either leave it as is and accept the compromise or 2) Redesign everything so that the straight staircase fits differently?

your rooms are completely oversized. 200 sqm is indeed large, but no one needs a guest bathroom with 9 sqm, a kitchen with 28 sqm(!!), a children's room with 25 sqm, and a main bathroom with 23 sqm(!!!). When you furnish the rooms, it looks like it was slapped together
