160 sqm hillside house / floor plan optimization

Good day everyone!
My partner and I have been planning the house for quite some time, but now that we are approaching the "home stretch" and will soon be able to submit the building application, I am doubting everything. I am very unsure whether the ground floor is too "cramped" and whether the entrance area with its 2 m width is too narrow.
Furthermore, I originally wanted a straight staircase, but it does not fit into the hallway. That’s why the draftsman suggested the landing staircase shown. But isn’t it strange if the staircase start is practically in the middle of the room?
We chose the recessed entrance so that the house has something "special", "more open" from the outside. This will also be highlighted with a different color.
I would really appreciate constructive criticism, comments, ideas, questions, etc.!

Best regards
Anna

House design
Who designed it:
The design comes from me and our construction company tried to implement it accordingly

What do you especially like? Why? The basement with the open design
What do you not like? Why? The ground floor looks very cramped
Preferred heating technology: we have to use district heating

If you have to do without, which details/extensions
-can you do without: the hobby / TV room, access from garage to the house
-can you not do without: dressing room, pantry

Why did the design turn out the way it is now?

We are building into the slope but want the living area in the basement with direct access to the garden.
However, I found it difficult to sensibly place the entrance area on the ground floor so that strangers (parcel deliverers, delivery services, etc.) do not find themselves directly in the private area of the ground floor (i.e. cannot see directly into the bedroom or downstairs from the front door). I hope you understand what I mean.
Our construction company implemented it accordingly.

A nice design for a small family who can live without much "stuff," as storage space is limited. I think that's good and have also been living in our house with limited storage space for about 1.5 years. It does us good not to overwhelm ourselves with stuff. I like the quite private area for the child - the more independent they become, the better such a constellation is. I can imagine that a "town villa hat" doesn't suit the house much. A slightly pitched shed roof, which brings a higher ceiling height on the south side, could give the house a special pep. You can also play with high bands of light there. For this house, I can also very well imagine a slightly raised parapet and flat roof with a non-visible photovoltaic system oriented primarily to the east.
Here are a few considerations:

[*]The entrance hall has many square meters and yet little space for a wardrobe. --> high construction costs for little utility value.
[*]I would rethink the living area - why do you want to sit with your back to the window - especially since there is a TV room. Better to look out into the garden than at a cabinet.
[*]Consider adding another window to the living area; you can never have enough light and can block it out on very sunny days. Possibly also design the middle pane in the living room as a walk-through opening to the garden - fresh air is a contribution to quality of life for many months of the year. Instinctively, this would also be the place where the "running paths" most frequently lead outside.
[*]A window band above the bed provides morning sun.
[*]Try furnishing the guest room to see how you can get past the bed into the technical room. I would possibly also make the access to the technical room from outside (directly or through the storage room). From experience, I can say that this is not a practical disadvantage.
[*]Who uses the TV room? For a teenager, that could bring noise conflicts at bedtime.

I would probably mirror the living level, then the kitchen and utility room would be next to each other, and yes, it would require more windows. For the kitchen - the main workplace in the house - there are IMO too few windows planned anyway - it would be too dark for me - you always work with artificial light there.

With the existing floor plan, I would rotate the kitchen furnishings 90° clockwise - the island is planned way too small to be sufficient for cooktop & sink; ideally, it should be at least 320-360cm long. - then equip the wall with windows so that there is light and a view.

Omit the door between garage/house, but plan a canopy from the garage to the front door; then there is space for coat cupboards and a seating area to change shoes.

Is it allowed to build in the setback area at the bottom right? Fixed glazing and double doors in the living room? I would do it exactly the other way around. Where there is furniture, fixed, and where there is no furniture, the exit to the terrace. Is the terrace at the top of the plan?

Thank you for the good comments so far! I have also thought about many things and would like to explain:

Leave out the door between garage/house, instead plan a canopy from the garage to the front door; then there is also space for wardrobe cabinets and a seat for changing shoes.

The basement is deliberately placed this way because we want to put our "main terrace" in the southwest. That means once around the corner, so you can go directly from the kitchen to the terrace. I will visualize the kitchen idea! Thanks for the hint. In a previous floor plan, we had planned a roof and left out the direct passage. Maybe we should better realize it like that again. Unfortunately, you can hardly put anything meaningful on the left wall in the entrance area.

Is it allowed to build in the setback area at the bottom right?

Fixed glazing and double doors in the living room? I would do exactly the opposite. Where there are furniture fixed, and where there are no furniture the exit to the terrace. Is the terrace at the top of the plan?

Yes, we are allowed to build somewhat over the building boundary. We have already had that approved through a building inquiry. The terrace was once planned around the corner towards the kitchen. So from the dining table window to the end of the kitchen.

With the existing floor plan, I would rotate the kitchen furniture 90° clockwise - the island is planned far too small to be sufficient for the cooktop & sink; it should ideally be at least 320-360 cm long. - then equip the wall with windows so that you have light and a view.

So like this? The kitchen island would now be 3.20 m long. I liked the concept of a hidden pantry in the other version.
