Single-family house with gable roof, without basement - Feedback desired

I am also not a fan of many pieces of furniture, but a fan of the space under the stairs. Only the things should, in my opinion, be stored where they are needed. I don’t have dishes that are only used twice a year, but placemats, candles, and such should be within reach. The kitchen cabinets could be helpful here. But storing everything under the stairs quickly reaches the stairs’ capacity, even if it is 1.80 meters high, this storage space. Somewhere and somehow the things have to be placed, possibly on a shelf at the edge, or just further forward. The space is therefore strictly limited—I know that, I have our wardrobe under a staircase.
If you are not a fan of individual or small furniture but can’t do without them, you plan the rooms so that behind the doors there is a corner of a wall where a cabinet can be placed without particularly disturbing or standing out.
Or you plan a partition wall where later you don’t always stumble over a dresser or sideboard.
Or you plan a niche right away where a built-in cabinet has space. That could be done here, for example, between the kitchen and hallway, but I wouldn’t do that because, in my opinion, a door needs to go there.
Otherwise, I don’t see such common planning tools applied at all, rather the opposite.
How the dining/living area looks or appears, I have already mentioned. But I see absolutely no place for a sideboard there. And due to the side openings of the partition wall as well as side openings like door and windows, the view is very cluttered and restless.


Regarding the overbuilt cables: maybe that is fixed in the state building code?!? In NDS it is prohibited to lay floor slabs over cables in case something needs to be repaired later. But with us, this boundary construction would not be possible either, because the garages are built over with living space, but that is probably correct here, otherwise the planning would be pointless. I just hope that everything is fixed in writing with the building authority.

The 160m² come about due to the financing. We receive a very advantageous loan for this. Without it, we cannot afford the house. It is not included in the development plan. It is a "special feature" in RLP.

By the lines, do you mean the supply / disposal lines? That strongly depends on the provider. Here in the area, I have heard everything from "the entire house needs to be redesigned for that" to "We have laid the lines completely across under the house." One of the builders here in the area said that laying the lines under the garage is no problem. He has done that before. In the worst case, I have to swap the WC with the HAR. That would be a tragedy for my darling.

Regarding the furnishing of the living room: There are some premises here. I myself am not very interested in watching TV, but rather in the view. Therefore, it is obligatory for me that at least the recliner faces south. Furthermore, I don’t like sitting with my back to the window or passage. It’s just a personal quirk. However, this limits the couch / TV orientation to west-east or east-west. Furthermore, the view towards the southwest is blocked by the gabion. This makes the living room planning quite tricky. The cramped space of the ground floor then does the rest. The wall in the living room is, as mentioned, not obligatory, as long as it works with the statics. My first idea was to build a sliding wall with a height of 120 cm and a sideboard on each side. I could connect that with a floor box and slide it into the living room or the dining room depending on space needs. Something like in the picture "room divider," only sliding and half-high. But my darling thinks that’s stupid.

I am not allowed to publish the architect’s plans. There is an NDA. Briefly on the main points:
- Much smaller living / dining area
- Kitchen 7.8m² as a passage to the living / dining area
- An additional room on the ground floor, two children’s rooms in the attic
- No further expansion possibilities for family planning
- No pantry, no HAR, no double garage
- instead, laundry room on the upper floor and a lot of window area

I have attached an alternative for the living room planning. What do you think?

What I don't understand .. somewhere you wrote that the partition wall between dining and living is due to the static structure. How is a 120 cm high wall supposed to fulfill that?

My first idea was to build a movable wall 120 cm high with a sideboard on each side

What I don’t understand .. somewhere you wrote that the partition wall between dining/living is due to structural reasons. How is a 120 cm high wall supposed to fulfill that?

The wall in the living room is, as mentioned, not mandatory, as long as the structural engineering works out. We don’t have the structural engineering yet. If the structural engineer says it’s feasible, then we will leave it out / make it movable / half-height.

Movable, half-high... what advantage do you expect from that?

Movable, half-height... what advantage do you expect from that?

We currently have a couch standing in the middle of the room and a TV squeezed into the corner because there simply is no wall space. I want to avoid that in the new house.
With a half-height movable solution, I can create about 3.2 meters of space both in the living room and the dining room for, for example, a couch, bench, sideboard, TV, etc. This way, the sense of space in the 40 m² is not lost.
