Floor plan optimization for a gable roof house with dormers, 160 sqm

Hello dear home builders,

after I already explored the financial framework a bit last year, we initially had bad luck with the land allocation
But by chance we have now still got a plot, so it should finally get started now
Therefore, we have sketched it ourselves:

Development plan/Restrictions
Size of the plot: 820 sqm
Slope: rises evenly by 2 meters from north to south, flat from east to west
Floor area ratio: 0.3
Building window, building line and boundary: 5 m distance from the roads
Edge development: boundary development allowed towards the neighbor
Number of parking spaces: min. 2 per house
Number of floors: 2
Roof shape: no restriction (min. 25° roof pitch)
Orientation: driveway from street 2 (=east)
Maximum heights/limits: eaves height 5.7 m (top edge of floor to cut extended outer wall with roof surface), ridge height: 12 m
Further requirements: roof must be red

Requirements of the builders
Style, roof shape, building type: gable roof with dormers to the east and west and preferably high knee wall > 2 m (style similar to Roth Massivhaus Modena or Helma Chemnitz)
Basement, floors: 2 full floors without basement
Number of persons, age: 4 (33, 33, 2, 0)
Space requirements:
 - Ground floor: kitchen, dining room, living room, guest room/office, utility room, WC with shower
 - Upper floor: 2 children's rooms, bedroom (optional with dressing room), bathroom, possibly mini-office or room for washing machine/dryer
Office: family use or home office? Home office
Guests per year: 2 for approx. 14 overnight stays (spread over the year)
Open kitchen, kitchen island: yes
Number of dining seats: 6
Fireplace: no
Music/stereo wall: yes
Balcony, roof terrace: terrace on ground floor with southwest orientation
Garage, carport: double garage with access to utility room

House design
Who designed it: Do-it-yourself
What do you especially like? Why? Good use of the dormer windows
What do you not like? Why? unfortunately only a quarter-turn staircase (-> wish would be a landing or straight staircase), house is probably a bit too big (more space is simply needed downstairs...)
Price estimate according to architect/planner: 400k
Personal price limit for the house, incl. equipment: 380k incl. garage
Preferred heating technology: air-to-water heat pump (KfW55) (possibly + photovoltaics)

If you have to give up something, on which details/expansions
-can you give up: pantry in the kitchen; dressing room in the master bedroom; additional room '???' in the upper floor dormer in the upper floor that serves as a canopy for the front door
-can you not give up: large cooking/dining/living area with kitchen island and access to terrace, guest room or extra room for home office, equally sized children’s rooms

Why is the design as it is now? Accommodation of all required rooms, even distribution of windows

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

[*]Where can we still optimize?
[*]How can the passage from the utility room to the garage be implemented? The house’s floor slab must be higher than the garage’s (min. 50 cm) -> then there could be a problem with steps in the garage with door.

Attached the simplified house with exterior dimensions 11x11 and a garage 9x9, for the latter 7x7 would probably also suffice. As well as the first floor plans (everything is oriented north)

Thanks in advance for your feedback

That's much bigger, the house, than 160sqm?!

can you do without: pantry in the kitchen;

As it is located, it is also somewhat superfluous. The top right corner (between guest bathroom and garage), what is that? Toilet is missing, 3.7sqm is a bit tight. What kind of furniture is that in the kitchen with a depth of about one meter?

How can the passage from the utility room to the garage be implemented?

Why? Leave it out, the entrance to the house is quite quickly accessible.

I'll put it this way: your open-plan room is too long and narrow. The hallway is also quite stretched, but there's no space for wardrobe cabinets. The living room is too small for regular guests. However, the house width is wider compared to similar houses. Something is wrong there. Also upstairs: 25sqm bedroom with walk-in closet. Where others manage well with 3 meters, you make it 4. The children's rooms are also quite large.

It seems to me that you are not good with lengths and sizes. You can hardly estimate what is necessary and/or what is too much and thereby bloats the house. I see your 400000 as far too high and recommend an architect.

Thank you for your feedback
Many things are also reflected in our thoughts, but unfortunately not in the floor plan.

Isn't the house much bigger than 160 sqm?!

Yes, that's why we still need to somehow reduce the sqm here...

What is the corner at the top right of the plan (between the guest bathroom and the garage)?

House connections like electricity and so on must not be built over, so the house connections would go there.

What kind of furniture is that in the kitchen with an estimated depth of one meter?

Cooking island with a size of approx. 1.8 x 1.2 m

The bedroom can also be smaller - like other rooms above as well.
The problem is just that the desired cross gables dictate or limit the rooms in a certain way.

If you place the headboard of the double bed against the top wall, you can a) reduce the room size b) use it better. In the dressing room, the distance between the wardrobes should also be about 1m to be properly usable. If there is a dressing room, the access to the bedroom should also be through the dressing room; that is the point, so that the person who gets dressed earlier does not disturb the one who is still/already in bed.

In the kitchen, you need a row spacing of 100-120cm. YPG was probably asking about the furniture on the right side in the kitchen. I also wonder what is planned there. The pantry is useless because of its small size.

The strange narrow appendages cannot be used; to be usable, room widths of about 130cm are needed.

The bay window above the entrance is absolutely dispensable, a porch that sensibly extends to the garage and is preferably less than 1m deep will do.

House connections like electricity and the like must not be built over, which is why the house connections would go there.

Oh, and who is supposed to work there? Connections also have to be accessible.

Cooking island with a size of approx. 1.8 x 1.2 m

1.20 by 1.80? The proportions are not right...

YPG was asking in my opinion about the furniture on the right side in the kitchen.

Yes, the 2.45 in width...
It is all quite strange.
I would put it in the round file and immediately erase it from memory and go to the architect with a room plan.

YPG asked in my opinion about the furniture on the right side of the kitchen. I also wonder what is planned there.

I misunderstood that then; tall cabinets are simply supposed to go there (with oven/steam cooker).

The bay window above the entrance is absolutely dispensable

I think so now as well.
