Floor plan design of a 9x13m gable roof house with an attached 6x9m attic

I haven't reread everything now, but an entrance on the eaves side of the house would probably solve most of the floor plan problems, at least the corridor would be gone. Is that really not possible?

Originally, I wanted to plan it that way too. For that, either the house would have to be moved further forward (where the plot narrows again a bit and the 9m then becomes tight again) or the garage further back (and they only want to approve 5m for me instead of the originally planned 7m) in front of the garage.

So, I’m just puzzling away here with Tetris and walls, and now I’ve backtracked.
However, I’m also somewhat half-hearted about it: on the one hand, it’s about the optimum for the biker, on the other hand, I initially said that this plan involves biker misconceptions that I can’t support.
I have also never understood, as a mature adult, not using the main entrance and why one always wants to disappear through the garage into a side room that has nothing to do with the entrance and rather still has the white laundry lying on the floor.

Well, at the latest when she lives there, she will notice that the garage isn’t as magical as the gallery room.
I remind you that this room (hopefully) will be flooded with light, thereby naturally also somewhat warmer than elsewhere, where there is only a roof window. Maybe this is not the right place for bike training?!

And what is the cellar intended for now?

You can do a lot. With this idea, I ask why everything else should be so locked up, but now suddenly a cellar staircase is supposed to provide transparency. A steel staircase has many disadvantages: noise, vibration, cold. It’s pretty if you look at it prettily. A glass wall takes up your floor space. Or what do you mean by a steel staircase?

Yes, most of them are indeed either tubular or narrow. Usually, that is intentional. I also don’t see most of them as age-appropriate. They simply lack the space.

Here are my two variants (with different furnishing; I haven’t saved small furniture)

Thank you!
Regarding the two variants, I have somewhat distanced myself from the idea of a straight staircase. In my opinion, its open, transparent form only works if you don’t build a cellar staircase beneath it.
Otherwise, you would see the cellar entrance directly from the house entrance area.
Also, then there is no room again for a proper cloakroom when you enter the door, as you rightly pointed out based on my first amateurish draft.

I also want to stick to the idea of a kitchen as open as possible and not create a “kitchen corridor” behind the stairs.

What is the approximate space requirement of the other staircase you showed compared to the two-flight staircase with landing in my sketch?
I assume that it takes up less space in the house’s transverse direction, and then, together with a slightly “shorter” kitchen row or kitchen island, you can make the rooms on the other side, including the living area, somewhat more spacious (that’s how I understand this variant anyway)?
My original thought with both the straight and the landing staircase was the easier and safer usability especially in old age. But if you mostly stay on the ground floor in advanced age anyway, maybe compromises can be made.

The now straighter, less convoluted access to the dressing room with the more forward entrance to the bedroom (without having to go through a corridor first) makes sense.

I’m afraid I already know what you will think again (without you having to say it again). But I believe I need the cellar (even if only a partial cellar) not just for house technology but also for my bicycles and other “superfluous stuff,” including a hobby room. The double garage is “occupied” with cars and a motorcycle.

What is the approximate space requirement of the other staircase you showed compared to the two-flight staircase with landing in my sketch?

Yes, I was just following one intention, because the "long hallway" is there anyway. So you might as well use it. But you're right: I sometimes forget that a basement is supposed to be built. An alternative would be to equip the basement stairs with a door and side wall.

I need space not only for the building services but also for my bikes and other "superfluous stuff," including a workshop. The double garage is "occupied" with cars and a motorcycle.

You don’t seriously want to carry bikes up and down, do you? Then you have to make sure that opposite the basement stair access there is enough space and not immediately a wall, so that you can maneuver a bike of 200 cm length around the corner. Actually, beside the motorcycle and cars, two or three bikes should also fit in a 6 x 9 garage. I’m just saying.

(and they only want to approve 5 m instead of my originally intended 7 m) in front of the garage

What is the reason for that?

The space for the staircase also depends on the floor height. I currently have a clear height of 2.65 m in my 3D program for both the ground floor and the upper floor. If you leave out the attic (where it is hardly possible to store anything anyway) in favor of an internally open gable upwards

For what reason?

First of all, I have to say that as a basis for the new building, the existing plot along the existing property should/must be divided.

My submitted plan included a 7m recessed attic attached on the left to the existing building and the house built with a gable towards the street set back 3m, with a carport planned on the right up to the property boundary. The first thing that was not approved, with reference to too much sealed surface, were the "many" parking spaces, so I first removed the carport from the plan. Then it was suddenly said that the district or city planners had concerns because I did not want to build directly (then with the eaves towards the street). The district planning actually did not want me to build a detached house at all because the houses in the immediate vicinity (except for an old half-timbered house to the right of the property) also do not stand free. They then said they could only agree to a property division with a distance of 3m from the existing building. However, my plot width would no longer have been sufficient for the double garage. I then made a (deliberately nonsensical) alternative proposal to place the attic completely set back on the southeast property boundary (with a "nice" sealed access road through the entire property), as the property widens noticeably there and then, even with the plot 3m narrower, there is space for attic and house again. I also argued that dividing with a 3m distance would create a 3m wide strip of dirt that neither the owner of the existing building nor the new owner of the divided plot would take care of, and this is not beneficial to the local appearance. Afterwards, they approved me—after I had provided photos of my vehicles to be housed in the attic and argued that I really needed the space or remaining parking spaces—the 3m set-back house with gable towards the street, but only with a 5 m driveway (again with reference to surface sealing). Furthermore, the fire gable of the existing building must be greened or otherwise designed... Then I could/might also provide a property division without 3m distance to the existing building.

At times, I felt like I was at an oriental bazaar or at the mercy of the arbitrariness of local planners and monument preservation (the half-timbered house to the right is a listed building). They also did not want to accept more than 50 cm roof overhang until I provided photos of the neighboring houses that partly have up to 1m roof overhang. Then the colleagues were satisfied with 1m as well.

I have now installed a somewhat less deep staircase after consulting with a stair builder and redesigned the kitchen into a U-shape. The background was the desire to make the living and ground floor sleeping area a bit wider. At the same time, I shortened the house by 30 cm again. I initially did not recess the entrance area inward. If the house were allowed to be set back 1 meter to the rear, this might be sensible (even though it would reduce space inside) to achieve a 1 meter deep covered area flush with the garage. In the relatively wide hallway, a wardrobe with a bench could be installed (then the utility room would be designed narrower). Alternatively, a wardrobe wall could also be accommodated in the utility room, as shown in the sketch.
