Single-family house floor plan - looking for two options, tips, and experiences

Hello, we want to build a roughly 200 sqm detached house without a basement, solid construction.
Here are the details:

Development plan/restrictions
Plot size 520
Slope no
Floor area ratio 0.4
Floor space index
Building window, building line and boundary
Edge development no
Number of parking spaces 2
Number of floors 1.5
Roof shape gable
Style classic
Garden orientation >direction west
Maximum heights/limits 6.50 eaves /10.20 ridge height
Further requirements Water must go into the ditch, north above the plot

Client requirements
Style, roof shape, building type
Basement no
Number of people, age 2 adults (35-40) 2 children (2 years and another planned)
Space requirements on ground floor, upper floor Open spacious living/dining area, technical room, guest toilet, 2 children's rooms, bedroom, dressing room, 2 bathrooms, office
Office: family use or home office? Home office + ironing, drying laundry
Overnight guests per year 6. Family from abroad, always staying several days.
Open or closed architecture open
Conservative or modern construction modern
Open kitchen, cooking island yes
Number of dining seats 8
Fireplace yes
Music/stereo wall
Loggia
Carport, utility garage attached to the east side of the house
Further wishes/special features/daily routine, also reasons why this or that should or should not be
Usually only one person at a time in the office. Guest room used as ironing and laundry drying room.
The technical room should also store supplies, drinks and laundry?
Loggia faces sunset and “mountains”. The plot is approx. 70 cm lower than the field path (8 meters from the house, 5 meters from the boundary)

House design
Who made the plan:
- Planner from a construction company
What do you particularly like? Why? All rooms are there. The sizes roughly fit.
What do you not like? Why? Size of the technical room, entrance area, possibly window layout in the living/dining room, upstairs bathroom is small?
Price estimate according to architect/planner: 450k
Personal price limit for the house including fixtures: 600k
Preferred heating technology: heat pump with underfloor heating

If you have to do without, on which details/extensions
- can you do without:
- cannot do without: second bathroom (should be children’s bathroom)

Why is the design the way it is now? For example
What makes it particularly good or bad in your eyes?
Plot conditions

What is the most important/basic question about the floor plan summarized in 130 characters?
1. Laundry room upstairs or downstairs?
Upper floor: that is where laundry originates, but then drying and possibly ironing downstairs?
Gives more space in technical room. But children's rooms become smaller.
Ground floor: Laundry can go straight through the kitchen to the line, you can check when it’s done when you are in the kitchen/living room.
2. Entrance front or side?
Front - there is an additional entrance from the garage. The one with 3 m width, however, is narrow.
Utility garage can be longer, a carport can be placed in front of the garage. Long, relatively narrow corridor which could be dark.
Side: Utility garage is smaller, carport must go elsewhere.
3. Windows in the living room
The 5m element is currently planned on the left side. The “better” view would probably be if the element was shifted all the way to the right. That way you look towards the neighboring house (not there yet). But the field path to the north is also used by walkers and such. So possibly more visible. Would you shift the window to the right? Then the question is where to place the couch and TV.
4. TV/couch in the living room: best arrangement.
Where should the TV go best and where the couch?

We currently also own the neighboring plot, the hatched area we want to separate and sell the rest of the plot again. We are building on plot 7372.
The exterior view somehow does not please me, but my husband likes it.

We are also grateful for other tips!

... unfortunately, I can't see your attachments. Best to upload them again.

... there are increasingly often problems with attachments .. there is then a symbol "Attachments" in the post, but no images are visible.

Off topic

With Tapatalk, the attachments are visible, but often the texts are missing in some posts

On the drafts: I don't like the hallway situation in the first draft (much too elongated), whereas I prefer the upper floor. However, one could place the main entrance by the garage in the first draft and modify the utility room a bit. Possibly also swap the entrance and stairs so that there is an obvious access to the dining room. As a utility room for 4 people, I find the chamber upstairs too small, but necessary as a storage room. Children's bathroom: is that the one on the ground floor? I find the loggia on the upper floor unnecessary.

... with normal use with laptop and Firefox 57.0 they are not visible.

I uploaded the attachments from the iPad. Should I try again from the PC? It also took me forever to try.

Thanks for the comment!
The chamber upstairs would only be for laundry. The utility room stays downstairs in all versions.
The children's bathroom, once they are old enough, will be the bathroom on the ground floor.
The house shape will probably be like the first draft, which is also drawn on the plot.
The loggia -> my husband does not want to give up on that because he thinks that only from there you can really enjoy the beautiful view and sunset. Since the plot is lower than the field path, you don’t really see much from the living room (unless you move the windows ;-)).
