Floor plan design of a 4-gable house, main gable, double garage

Hello everyone,
we are about to submit our building application. The floor plan is now ready, and I would like to ask if you possibly have any suggestions for improvement! (Sometimes you become partially blind and don’t see everything anymore)

Development plan/restrictions:
Size of the plot: 1200 sqm (24mx50m)
Slope: NO
Floor area ratio: 0.2
Plot ratio: I don’t know
Building window, building line and boundary: 21m wide, 18m deep
Number of floors: 1 floor
Roof shape: no specification
Style: no specification
Orientation: no specification
Other: Access to the plot over a small ditch.

Requirements of the builders:
Style, roof shape, building type: Herrengiebel
Number of people, age: 2x adults (27-28) + planned 2 children in the next 2-3 years
Space requirements on the ground floor: Kitchen facing the street with utility room at the garage, guest WC with shower, living room with fireplace, (what I am still thinking about is my TV corner, the sofa is too far away from the TV but if I move it closer I might collide with the fireplace? I can hardly estimate the size on the floor plan) do you have any ideas?

Space requirements upstairs: 1x bedroom, 2 children’s rooms, (walk-in closet should not be directly connected to the bedroom! (I get up earlier in the morning and want to quietly choose my clothes))
Office: family use or home office?: Office / guest room
Open kitchen, kitchen island: open kitchen no. Kitchen island possibly like drawn? We haven’t been to the kitchen studio yet...
Number of dining seats in the kitchen: 5
Number of dining seats in the living room: 9+
Fireplace: yes in the living room (we want to leave it as a masonry fireplace)
Music/stereo wall: I will check during shell construction if I lay speaker cables
Balcony, roof terrace: NO
Garage, carport: Yes double garage 6x9m on the boundary
Useful garden, greenhouse: planned but we are not stressing about it

I hope this is detailed enough to hear your opinions.

Thank you in advance.

Do you have dimensions? I have my doubts, for example, that you have enough circulation space in the master bedroom. The dressing room has very little reasonable storage space - it might work with a carpenter, but not with Ikea. The children's rooms are relatively small - although the dimensions would be interesting here as well - are those living areas or floor areas of the rooms? Have you fallen in love with the gables? If necessary, I would do without them and instead choose a higher knee wall and make the house one meter wider.

Right, it crashes then...

I wouldn’t want the kids’ room next to our bedroom – so I would swap it with the dressing room or the office.

EG: From the kitchen to the living room through two doors or through the hallway is an absolute no-go for me. DG: Children's rooms are even too small for me!!! This could also apply to the bedroom. The guest gets by far the largest room? Children's rooms should be at least 12 sqm.

The building type is to be: country house with a gable (?),
which inevitably must result in a symmetrical floor plan and a symmetrical façade? As often happens,
the floor plans are then forced into a predefined shape, with functional losses and strange detail solutions.
I would develop the floor plan from the functional relationships: room program, usage flows, family habits.
From this arises an organigram of the floor plan, which must be brought into the 3rd dimension and adapted to the site situation (development plan requirements, building law) and to a design concept that defines the architecture of the house.
Of course, also to the construction budget.

I see many of these forced situations in the floor plan,
which in my opinion should be improved before the building permit application.
The house can be built as an external form and also understood design-wise.
Inside this does not succeed.

- Entrance situation too large with an overly space-consuming staircase of the castle staircase type
- Kitchen and living room separated by the hallway
- Terrace in NW. No terrace doors in SW
- Strange room shapes due to the staircase layout. I am not a fan of 45° angles and slanting walls as well as "appendage" corners.
They mostly represent spatial makeshift solutions, as also on the upper floor.
This results in poorly usable, difficult to furnish corners
- Dressing room/bathroom/master bedroom should spatially follow one another if you already allow yourself the luxury of a dressing room.
In any case, DR + MBR should be adjacent and connected
- Bathroom/upper floor: I find the bidet/urinal unnecessary and placed too tightly.
I would swap the toilet and the shower.
- Kitchen, bathroom/ground floor, and bathroom/upper floor are not next to or above each other.
How are the installation lines to be routed, for example without bulkheads under the ceiling over the ground floor?
Also from this perspective,
the bathtub and the urinal/bidet in the upstairs bathroom are difficult to connect.
Where is the soil pipe with ventilation over the roof planned for all drainage points?
Where is the house connection room located?
- The two roof ridges have a minimal height difference.
This is architecturally indecisive and tricky to construct.
Depending on the roof covering,
this leads at the intersection to unattractive detail solutions with a lot of sheet metal use.

Is the floor plan the result of a professional planning by the builder/general contractor or is it a self-made sketch?
