Single-family house, staggered storey, prefabricated construction method

Hello to the forum. My first post, I have been reading for a while. Son (8 months), wife and I (37 and 38) are planning our own home. We have already purchased a 620 sqm plot in a new development area.
The development plan (location in southern Hesse) only allows 1 full floor, so we have decided on a staggered design (75% of the ground floor area on the 1st floor). I tend to prefer a flat roof, my wife rather a hip roof. A photovoltaic system is to be installed on the roof, a battery storage system inside the house. It will probably be towards a KfW efficiency house 40+. A basement is not planned, mainly for cost reasons. The building land is fairly flat, about 1.5 meters slope from east to west.

About the house itself: Open living-cooking-dining area, pantry, guest/work room, straight open staircase, 2 children's rooms, parents' area with dressing room. For various reasons it will be a house from a prefabricated house provider; a branch of the company is on site.
The company’s architect has already worked on it and made a first draft, where we have already made some adjustments. You can see the current planning status attached. Our difficulties are still in the kitchen area or on the west front: there are the utility room and pantry, we would prefer the kitchen with a view towards the street/west/evening sun, but we cannot accommodate that properly.
On the northwest property boundary, a double garage 3x6 m plus hobby workshop 3x3 m is to be built without interior walls. Also, the whole house is to be moved further to the northeast in order to have the most space for the garden in the southwest.

My wife and I somehow currently lack a fresh perspective, so I am turning to you. We would be happy about criticism and suggestions...

Damn, I probably posted the thread in the wrong forum section, it can be moved if needed. Here are some additional infos:

Development plan/restrictions 620 sqm Slight slope, from east to west 1.5 to 2 meters (survey in progress) Floor area ratio 0.4 Plot ratio 0.4 Edge of field location 1 full floor Roof shape doesn’t matter Open construction style, detached house Otherwise, according to the development plan, no further specifications

Client requirements Style direction Bauhaus or urban villa No basement (cost reasons), 1 full floor (ground floor), 1 recessed floor (upper floor) Number of people currently 3, possibly 4 (>1 year old, 37 and 38 years old) Space requirement ground floor and upper floor together approx. 200-220 sqm Office: family use or for guests Open or closed architecture: open Conservative or modern construction: modern Open kitchen, cooking island yes Number of dining seats 8-10 Possibly a fireplace, but only kerosene Balcony Double garage with open workshop (mountain bikes) Utility garden, greenhouse no

House design Who made the plan: - Planner from a construction company What do you particularly like? Why? What don’t you like? The kitchen location as well as the location of the utility room and pantry, which have the best view to the west. Price estimate according to architect/planner: €500,000 - 600,000 Personal price limit for the house, including equipment: €600,000, the plot is already paid for and is not included in these costs. Favored heating technology: air-water heat pump or air-air heat pump

If you have to do without, which details/expansions - can you do without: ? - can’t you do without: ?

Why did the design turn out the way it is now? E.g. Based on a standard design from a prefabricated house provider, but with some extensions. What makes it particularly good or bad in your opinion?

What is the most important/fundamental question about the floor plan summarized in 130 characters? What do we do with the kitchen location? Is it bright enough? Is there a possibility to place the kitchen on the west wall (street side)?

View of the village means: great view.
Dining room is annoying, right?
In short, I’ll just throw in the idea of rotating the house.
Or: better to move the ancillary rooms to the top of the plan, give up symmetry, entrance on the left side of the plan (corner), the rest will be resolved during planning.
I don’t find the upper floor good anyway, the ground floor would be quite nice otherwise. I would have suggested the extra hallway with cloakroom/built-in closet and moving the utility room door, but I would actually proceed against symmetry for once, as suggested.

Move the living room bay window down plan by a quarter to half a meter as a measure to prevent the Tetris look. Stepped and hipped roof is, in my opinion, a combination that takes some getting used to.

Valley view to the village means: great view. [...] but I would actually proceed against symmetry, as suggested.

Anyone who has a valley view and cares about symmetry at all, in my opinion, hasn't got a clue.

Valley view into the village means: great view.
Pantry is annoying, isn’t it?
In short, I’ll throw in the idea of rotating the house.
Or: better to move the ancillary rooms up on the plan, give up symmetry, entrance on the left side of the plan (corner), the rest will result from the planning.
I don’t find the upper floor round anyway, the ground floor would otherwise be quite nice. I would have now suggested the extra corridor with cloakroom/built-in wardrobe and moving the utility room door, but I would actually proceed against symmetry, as suggested.

Yes, the pantry bothers us the most, since it somehow has too good a location. But if I move it upwards on the plan, the distances from the garage, front door, and also the kitchen (which would then be at the bottom of the plan) are too far for me.
What do you find not round about the upper floor? We were very satisfied with the upper floor as it is (except for 2 additional windows each in Bedroom 1 at the top of the plan and Child 1 on the left side of the plan).
What I have not mentioned so far: a small cemetery borders the northern part of the property. The street at the bottom of the plan is a quiet residential street in the new development area.
With "valley view" I probably exaggerated: yes, it is the view towards the old town/city center and also an elevated location on our part, but there is also new construction opposite, so presumably only from the balcony on the west/street side will there be an unobstructed view.

Move the living room bay window a quarter to half a meter down on the plan, as a measure to prevent the Tetris look. Stepped and hipped roof is, in my opinion, a combination you have to get used to.
Anyone who has a valley view and is interested in symmetry at all, in my opinion, hasn't got it.

Sorry, I can’t follow you on the last sentence.
Moving the living room bay window down would reduce the terrace slightly, and perhaps we would need another support at the top right on the plan, right? Because of the flat roof... I have been processing my wife all the time. For her, it is also partly about storage space due to the lack of a basement... but the attic can’t be that big with a rather flat hipped roof in this form that you could sensibly store anything there.

The kitchen doesn't work like this, the line spacing is too large. What is this box on the right side of the island? Do you really need 3 showers? Child 1 should still get a window on the left side of the plan. Is all of the upper floor really supposed to be terrace? For what purpose? I would prefer a green roof. You can still walk on it or put up a clothes rack. I like the layout of the parents' area (access through the dressing room, bedroom not a walk-through room). Is the closet space in the dressing room sufficient? It might be nice to have a window at the top of the plan in the bedroom, from which you can enjoy the view of the fields from the bed along with the rising sun.
