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

But remember to allow enough freedom of movement.

A rather daring thought regarding the frontal view of the plank wall when entering the house. I hardly dare to say it out loud. Couldn't one design a freestanding steel staircase that is not embedded in the side wall and then replace the frontal "plank wall" with a glass railing with a view of the "daring staircase construction" down to the basement stairs and up to the stairs to the upper floor?

It is always so important to know the individual "craziness" (in a positive sense, of course) of people in order to find a good floor plan; I really like it when someone does something special for themselves/their partner. We have acquaintances where he likes to listen to loud music but would never wear headphones (3-room condominium) and they are still married.....ufff. I mostly wear my fluffy things on the gallery when I watch documentaries. For those who don't fit that way, they need doors or soon the phone number of a lawyer.
That makes sense to me with corridor/hallway, so I also believe that this curve is only planned because a "nonsensical curve" was already built in before. There are stylish floor plans, even for these spoiled "older people."
The staircase also somehow seems out of place to me but I lack the idea for it.

The extra room upstairs is needed to set up a few display cabinets for things that do not tolerate much light over time. My/our hobby is classic cars and old racing bikes. The "sports gallery" seems a bit (outrageously) large to me at least on the floor plan, although I would like the idea of working on bikes there (which I will not tell my wife though).

The topic of collecting has already been discussed-:)
A buddy of mine always had his two shiny Harleys standing in the living room and was happy with that.
I would never find anything "outrageous" that I currently enjoy doing; but dragging my whole life behind me would never occur to me and apart from a seahorse and a winner’s certificate at the youth sports games I would have nothing to hang up anyway; luckily, I was/am rather unsuccessful.

.....although I would like the idea of working on bikes there (which I will not tell my wife though).

Quickly comes a letter from the lawyer but luckily there is also a garage.
Okay, there are other birds than me but that is quite a special idea instead of lavender scent, the smell of grease in the air if you like that; then rather a nice, single-story extension or a spacious garden house where you can also watch the dusty old video cassettes with Danish westerns with the neighbor.
Does your wife at least know that you are planning a house? What does she say about the details planned so far that she knows?

Yes, so far she liked all my ideas (including those I now know were bad). She always gives me tips on where to place flower boxes... The most important thing for her are the walk-in closets. However, unlike me, she has a photographic memory for details and solutions she has seen during visits to prefabricated house model parks.
By the way, I am grateful for alternative staircase ideas (if you don't like "mine")...

Well then, it fits after all; that's what matters alone; by the way, I find the dressing rooms tiny, maybe you could pass that on-:). The stairs were a tough, annoying, but ultimately great topic for us; take a look at "Zeitform" also the hanging stairs. That's a super pleasant one-man operation, maybe he has the right idea for you or also tells you what is feasible.

That makes sense to me with hallway/hose, therefore I also believe that this curve is only planned because previously an “absurd curve” was already built in. There are nice floor plans, even for these spoiled “bestagers”.

So, I am currently puzzling and playing Tetris with walls, and now have backtracked. However, I am 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 planning contains biker thought errors that I cannot support as is. I have also never understood as a mature adult why one would not use the main entrance and why one always insists on disappearing 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.

My/our hobby is vintage cars and old racing bikes. The “sports gallery” seems to me at least on the floor plan a bit (outrageously) large, although I would like the idea of working on bikes there too (which I won’t tell my wife though).

Well, as soon as she lives there, she will realize that the garage is not as magical as the gallery room. I remind you that this room will (hopefully) be flooded with light, thus naturally also a bit warmer than elsewhere, where there is only one skylight. Maybe that’s not the right place for bike training?!

The extra room upstairs is needed to set up a few display cases for things that do not tolerate much light in the long run.

And what is the basement intended for now?

Couldn’t one design a freestanding steel staircase that is not embedded into the side wall and then replace the frontal “plank wall” with a glass railing looking down at the “daring stair construction” down to the basement stairs and up to the stairs to the upper floor?

You can do a lot. With the idea, I ask why otherwise everything should be so closed off, but now suddenly a basement stair should provide transparency. A steel staircase has many disadvantages: noise, vibration, coldness. It’s pretty, if you look at the pretty ones. A glass wall takes up your space. Or what do you mean by a steel staircase?

By the way, I find the dressing rooms puny, maybe you should tell them that. :)

Yes, most of them are indeed either narrow or tight. Usually, that is intentional. I also don’t see most of them as age-appropriate. There simply isn’t enough space for that. Here are my two variants (with different furnishing, I have not saved small furniture)

I have also never understood why a mature adult would not use 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.

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