Single-family house on a slope - floor plan optimization, please provide feedback

Hello,

I would like to hear your opinion. I planned a house 2 years ago, but unfortunately my mother became seriously ill, had to be cared for, and sadly passed away half a year ago, which caused my house plans to be put on hold.

Now I have regained strength. Originally, I wanted to build solidly myself, but I have discarded that plan and now it should be a prefabricated house. The groundwork was already completed because I want to build on an existing plot of land owned by my parents. I created the following floor plan together with a planner; the right side is the hillside side (See the other pictures for this). The utility room (HAR) would be in the dark corner, as well as the guest toilet. I want a nice open area. I also considered rotating the pantry by 90 degrees and placing it on the hillside side as well, since the hillside side is the north side and does not get sun. I would like to optimize the house a bit more. Perhaps also not use a 180-degree staircase; I am open to suggestions on this.



It would be great, of course, to integrate a (small) workspace.

One problem is, of course, the lighting conditions. Here is the view from the hillside to the house, side of the two WCs:



The corner of the house from the utility room would be staked out here (see wooden post):



For your information: The building next door will be demolished up to the knee wall and is to serve as a terrace, which would be accessible from the dining area. The edge corner of the house would start at the door still visible in the picture. I am also considering placing a part of the house on the old building (the lower floor remains, it is built on rock) to create more space on the side.

I am open to your feedback.

What immediately strikes me, you haven't planned any wardrobe at all?

You are building with a basement, right? If not, your utility room has to be twice as big, otherwise you won't be able to fit the technology in. If you remove the dressing room, you can also fit a study room in :-)

I haven't planned a wardrobe. I think that can be accommodated in the hallway.

No basement, instead we use the outbuilding. The utility room should normally fit the gas heating plus washing machine and dryer, right? Or you minimize the storage room and expand the utility room instead and use it as a storage room.

The dressing room is my wife's wish, I can't avoid that.

Is the bathroom size upstairs okay or is there maybe potential for savings here?

I am missing a lot of storage space in the house, where should vacuum cleaners, cleaning supplies, shoes, etc. go? You’re not going to treat yourself to a new build just to always want to run to the house next door because of these important little things...

The control cabinet still needs to go into the utility room, it takes up space and especially floor space, I would also plan a utility sink there.

The whole thing seems a bit thrown together and not well thought out to me.

The entrance area consists of a boring long hallway, where you want to squeeze in the coat rack. A single door then leads in a winding path around a questionable room divider into the kitchen. By the time you’ve managed to get there with the shopping bags, the milk is sour.

The direct path to the kitchen is blocked by the pantry – which, as you already mentioned, should at least be behind the kitchen on the right side according to the plan.
The bathroom layout is also not great. Although there are two windows, it is as dark as night in the bathtub. The bathroom is huge, yet there is a lack of space for the washing machine, vacuum cleaner, and so on.

Child 1 sleeps with their ear against the parents’ bedroom, although it is not absolutely necessary.
etc.

I think you should fill out the questionnaire and see what you actually need. Also, a site plan with north arrows and building boundaries of the plot. The discussion is hardly worthwhile before that.
