Hello everyone,
The floor plan is almost finished, and now I would like to hear your opinions. We can still make changes if needed.

Building levels: basement + ground floor
Roof style: gable roof
Client Requirements
Style, roof type, building type: gable roof
Basement, floors: basement + ground floor
Number of residents, age: 2 adults / 1 toddler
Space requirement on ground and upper floors: approx. 140 sqm (1,507 sq ft)

House Design
Designer: planner from a construction company
What do you especially like? Why? Mostly drawn according to our wishes
What don’t you like? Why? Dining area too narrow between kitchen and living room (the left kitchen unit must be this long (from left to right: raised dishwasher, oven and microwave stacked, door to pantry, side-by-side refrigerator, tall cabinet). On the right side, we are considering shortening it a bit to gain more space in the dining area.
Estimated cost according to architect/planner: €400,000
Personal budget limit for the house including fittings: €410,000
Preferred heating system: air-to-water heat pump with underfloor heating
If you have to give up something, which details/expansions
- can you give up: open
- can’t you give up: open
Why is the design as it is now?
We spent a long time drawing, changing, and adapting ourselves. This is the result of collaboration between the planner and our wishes.
Which wishes were implemented by the architect? All
Information:
The house will be a single-family home built in solid construction, KFW55 standard, with photovoltaic system, underfloor heating, air-to-water heat pump, gable roof with a 22° pitch. The family planning is complete with 2 adults and 1 toddler. The house is built on a sloped hillside plot with a 10% gradient, accessed from the street. The basement parts fully covered by earth are made of waterproof concrete, the rest is masonry. The south side faces the street and thus has the main terrace. The passage between kitchen and pantry is hidden behind a concealed door in the kitchen wall unit. From the entrance area to the pantry, access is either via a sliding door or a regular door opening towards the pantry. A lifting system for the lower bathroom is not required since the slope from bathroom to sewer will be 2.8%. The sewer connection on our property is located at a depth of 3.39 meters (11 ft). The house will also be built slightly higher than the street level. A backflow valve is, of course, planned. From the lower bathroom, there is another door leading into the rear garden (north/east). Instead of a deeper foundation due to the slope, the double garage (prefabricated garage) will have a transverse utility garage with a side door, 3 x 7 m (10 x 23 ft), so it can be used as storage / cellar / garden equipment space. The terrace will not extend as much around the corner as in the plan, allowing the ground to slope down more quickly there.
After so much planning, thinking, and revising, it is easy to become blind to details and overlook some things. Therefore, we appreciate any criticism, tips, tricks, and suggestions
Fire away & thank you very much in advance.

You could have figured it out yourself instead of making us start the discussion as if from scratch. Just now, I wanted to link you a similar thread, but then I saw it was your own: https://www.hausbau-forum.de/threads/eg-ug-mit-schlafraeumen-Bad-im-ug-was-meint-ihr-zur-Planung.33637/ – and in this one here: https://www.hausbau-forum.de/threads/Hanglage-einschaetzen.32724/ there was already information from the development plan. No, I did not come up with the idea on my own to post the floor plans under the thread regarding how extreme the slope on our plot is, because those two topics have nothing to do with each other. The other thread was about our self-made sketch without any plan from an architect or planning office, measurements of the property, and so on. If it makes sense to add new sketches under a four-month-old post, I can gladly do that.
Then why don’t you suggest what you think would be the right house design for the plot? Everything has already been discussed with the planning office. Basement and ground floor plus first floor—due to the sloping site, part of the basement is exposed at the back, and from the rear garden you look at a three-story single-family house over 9 meters (30 feet) high, certainly an impressive sight. You can also build without a basement, on a slab foundation with ground floor plus first floor. But that requires a huge fill volume to raise the house on a plinth, extensive landscaping of the outdoor areas, terracing the back garden just to get down the slope again, which means there’s barely any usable space at the back. I would therefore be very interested in your proposal, instead of just saying that the current plan is not suitable for the sloped site.

... should it plainly mean that under the valley end of the double garage, rotated by 90°, a third room module in the form of a prefabricated garage is inserted underneath?Yes, that's correct, why?

It's nice to see how your vision and the design come together. I like it.
For the garden area, I would reconsider having direct access from the bedroom—perhaps with a floor-to-ceiling window you can actually walk through. Thanks! Are you suggesting this instead of the access through the main bathroom?
Regarding the kitchen, I'm currently thinking about how to improve its layout myself.

So you have really thought everything through well to suit your family. It’s great how you can explain all your decisions. And if the house is set back 10 m (33 feet) from the street, the south-facing terrace will work. There are neighbors behind the house watching as well, so it might not be that “quiet” back there either.
I just made some slight changes to your floor plan, mainly removing the angled walls, enlarging the living room, and separating the guest bathroom from the living area. THANK YOU. I was just about to do the same thing with the angled wall near the pantry, which I didn’t like either. I will take a closer look at your revised ideas tomorrow. Thanks again.

Thanks! Do you mean instead of access through the main bathroom?No, in addition. The idea of having direct access to the bathroom is perfectly fine – no matter what others think. Our house is also built on a slope and every room (except the children's bathrooms and guest toilet) has at least one exit to the outside.

If it makes sense to add new sketches to a 4-month-old post, I’d be happy to do that. No, I just meant that, in my opinion, you should have placed the additional notes I provided about the origin of the story (and the excerpts from the zoning plan text) here at the beginning.

I would therefore be very interested to hear your suggestion, instead of only saying that what was planned here is not suitable for the sloping site. My wording is much sharper than my drawing skills – some get a bit offended (which is not my intention), but often it helps (and that’s what I’m trying to do). As I said, my drawing talent is barely enough to sketch a basic house figure, but I can try to explain it differently in words: here, based on a typical suburban planning fantasy for a regular plot, there was an attempt to simply impose it onto a sloping site; in my opinion, a better approach – although I can’t produce the perfect plan off the cuff – would be to adapt to the actual site conditions, to "accept" the plot as it is, and develop a design from there. Maybe even camping on the site once would help.

Basement and ground floor + first floor, then thanks to the sloping site a part of the basement is exposed at the back, and from the rear garden you look up at a single-family house more than 9 meters (30 feet) high and three stories tall, certainly quite a sight. I completely agree with you and find it commendable that you don’t want to imitate @Franky73.
