Hanging house 235 sqm with garage in basement on 3600 sqm plot

Hello everyone,
we would like to put the floor plan draft of our planned house up for discussion.
Main questions see questionnaire.

Development plan/Restrictions
Size of the plot: 3600 sqm
Slope: yes – south/east with just over 2 meters gradient in the house area
Site occupancy index, floor area ratio, building window, building line and boundary: No development plan, all §34 Building Code
Edge development: see above
Number of parking spaces: see above
Number of floors: In the surrounding area everything from 1-3 floors is present
Roof shape: In the surrounding area everything except shed and flat roofs is present
Style: none
Orientation: none
Maximum heights/limitations:
Other requirements: none

Requirements of the builders
Style, roof shape, building type: Gable roof house with large terrace roof and open design, the roof should continue from the balcony over the terrace and transition into a gable roof on the terrace. So no hipped roof cover.
Basement, floors: Basement + 2 full floors
Number of people, age: 2 adults (34/28)
Space requirements on ground floor, upper floor: GF – utility room, shower/WC, kitchen, pantry, dining, living room; UF – bathroom, dressing room, bedroom, children’s room, office, open area as reading corner (reserve for 2nd children’s room)
Office: 2-person home office
Overnight guests per year: few to none
Open or closed architecture: mix
Conservative or modern style: rather conservative. Solid house (Poroton outside, calcium silicate inside), few “frills”. No technical gimmicks. We are both people who like to be outdoors, so the covered terrace and the large terrace windows are especially important to us.
Open kitchen, cooking island: open kitchen to dining room without kitchen island (cook a lot, i.e. extractor hood extremely important and it should vent directly outside)
Number of dining seats: 6-8
Fireplace: yes
Music/stereo wall: no
Balcony, roof terrace: Balcony which transitions into the terrace
Garage, carport: double garage in the basement
Kitchen garden, greenhouse: huge garden with usable portion
Further wishes/special features/daily routine, also reasons why this or that should not be included
- central ventilation system, otherwise simple building technology
- large terrace windows (but it is enough if you can exit to the kitchen balcony door and to the dining-terrace window, the others (balcony, living room) can be fixed glazed)
- large pantry
- utility room on ground floor and below the bathroom, since laundry chute is desired

House design
By whom is the design:
- planner and our ideas
What do you especially like? Why?
- almost level exit to the terrace and connection to the balcony
- full utilization of the sunny location
- we like the floor plan very much
What do you not like? Why?
- entrance area with windbreak at GF as bottleneck, we probably use the entrance via the garage in the basement anyway
- concerns whether the dining area is too large
Price estimate according to architect/planner: none so far
Personal price limit for the house including equipment: none so far, still in price finding
Preferred heating technology: gas + tank

If you have to do without, which details/extensions
- you can do without:
- you cannot do without:

Why did the design turn out the way it is now?
Standard design from the planner: no
Corresponding/Which wishes were implemented by the architect:
- desire for lots of light and still roof over the terrace
- openness to the large garden
- enclosure to the neighbors “right” by the annex
- building with the slope (wider than deep)
What makes it particularly good or bad in your eyes?
- particularly good because it covers all our requirements but leaves some small doubts see above open.

What is the most important/basic question about the floor plan summarized in 130 characters?

We have doubts whether we have too many and too large window areas on the ground floor, also we are unsure if the dining area is too large and if so, how to reduce it without changing the floor plan too much.

We are looking forward to your feedback!
Best regards and many thanks in advance

Hello! So first of all, I think your floor plan is great! However, there are 2 things I really don’t like: - The vestibule would be a nightmare for me. Even in the 105 sqm semi-detached house of a friend, the vestibule is significantly bigger than in your palace. They love their vestibule because that's where the stroller is parked. We are also planning a much larger vestibule for our considerably smaller house, where you don’t step on each other’s feet and where a stroller fits. Can the utility room be made narrower? I also find the pantry and kitchen gigantic and could easily give up some space for a vestibule. - The second thing I really don’t like is this possibly second children’s room. I don’t know your private situation well enough, but overall you’re building a mega palace and the second child is supposed to get a good 10 sqm tiny room? Well, as I said, that of course completely depends on your personal situation. If it's pretty certain there will be at most one child, this criticism doesn’t apply. I really like the large dining room and would also build it like that if I had the money :)

Hello,
Could you please draw in the alignment, and if applicable, the neighboring buildings and/or trees. Also, please include the site plan. Additionally, I cannot see the roofing now, which is indirectly the focus here.

Ahem,
Do you walk out of the kitchen towards the terrace and then fall into the cellar hole? Or is that the balcony that darkens the only window in the cellar?
You have the terrace and next to it a car drives into the garage? You sit on a balcony and watch the same spectacle? The entrance is on one side, the garage driveway on another?
The chimney is missing on the upper floor and would theoretically stand in front of a window.
The refrigerator is in the way, the kitchen island is too narrow, and the kitchen itself has too long distances because it was planned too large for the room.
You don’t need a vestibule nowadays and it is terribly small. No family can move around in there.
There is no window concept for a nice facade?
At the latest, the bulges in the upper floor hallway show that the desire to plan was missing or the planning is incompetent.
Far too many partition walls that cut off the rooms from the light.
16 sqm bathroom, but a space-saving bathtub...
Shower and then first past the window “Good day, Mr. Neighbor”

I don’t believe in a planner. Sorry, but throw the thing away.

the kitchen area is much too large, the wind lobby much too small, where is the wardrobe?

Additionally, when entering the bathroom, you look directly at the toilet. So this privacy screen is actually not needed anymore ;) I also see imbalances in this plan. Some things are way too big, while others are too small. I also miss a [Garderobe].
