On which of these floor plans can we continue to build?

There is no need for my hint, the OP uses the same name in both forums. What is your name there, or do you just read silently?

I hadn't paid attention to the name at first, I am just a silent reader.

I like the first draft best. I would mirror it horizontally to bring the west sun into the living room.

Here is an alternative with the office upstairs and the storage room downstairs:

I have to admit, at first I did not read the entire text. I find some of the thoughts that bother you somewhat trivial. The bed niche for the children is cozy. You can't see the door from there – that's perfect. The bathroom door is fine as it is, the entrance door is the right size. It's a pity that you stumble up the stairs when you come in, but that’s still manageable. I would actually turn the living room door. I find the TV distance sufficient. The office would be too cramped and cluttered for me. The bathroom upstairs would be a bit too small for me. It’s doable – but in my dream house I want to be able to move around. Storage bunker without a window I find terrible. Especially that narrow nose. You don’t design rooms like that in a new building, that’s fiddly. But that’s the only flaw I notice. The reason for it are the exorbitant wishes in a very small space. Those bother me the most. By the way: With a flat roof, you can work very nicely with skylights in the upper floor corridor. This creates possibilities for a naturally lit corridor without it needing a wide and direct access to the outer wall.

First of all, attached again is the site plan. Somehow my related post got deleted.

@ypp: Somehow I have the feeling that we already know each other .

No need for my hint, the OP calls himself the same in both forums.

I briefly thought about calling myself differently here. But that would have been silly. The clever one would have seen the connection .

Have you once drawn in the existing or desired furniture to scale in all floor plans?

You write extensively about what goes into the study. Draw it in

… the sideboards are already mentally in place.

Yes, I have. The furniture drawn in the BT floor plan would be our furniture.
My approach here was to look at the floor plan neutrally and not immediately clutter it with furniture. But I can also present the floor plans furnished right away in the future.

Personally, I like the first ground floor best. The utility room door can be moved a bit closer to the kitchen. Direct access to the kitchen is not necessary. Better to put in a decent pantry cabinet.

And where then with the door to the utility room? Originally it was in the hallway where the wardrobe is drawn now.
The kitchen furnishings are still completely open. Tending towards either a U-shaped kitchen or a row with a peninsula.

It’s pointless just reading the requirements. That really takes away any desire to say a thing.

Which requirements do you mean exactly?
Here you are supposed to fill out the well-thought-out questionnaire and write what you like and don’t like about the floor plan.

Basically the decision is already made.

Which one would that be?

Lamp???

By light source I meant a window .

You’ve even practiced parking …

Isn’t this a legitimate way to find out how well you can get into the garage or not?

Do you prefer the strip on the west side instead of the east? For a house ten meters wide you would have two! strips minus garage, but then you lose windows. It’s the same either way: either a strip, so 3 meters of usable space (there are worse things), or no windows.

And what would you recommend to us?

A strip would be occupied by a garage all the way to the end of the terrace. On the other side, sooner or later a parking space would be added in the front area. In the garden-facing area, you could extend the terrace around the corner and/or do something for the children, e.g., a swing.

We ourselves are completely unsure.
If you place the garage on the east side, then you can still have a window on the west side in the ground floor; but the driveway is then a bit narrower. Cars in general will probably be bigger rather than smaller over time.

Here is another alternative with the office upstairs and storage downstairs:

Wow, thanks for this idea. It reminds me a little of a variant the architect once made available to us.
I understand the floor plan is already oriented accordingly? That is, garage and entrance on the east side and then a 4 m green strip on the west?
Just wondering, if the garage only starts after about 6 m house length, then it already protrudes out of the 13.5 m deep building envelope. I don’t know if this is compliant with the reasoning behind the development plan. A 9 m long garage would probably not be possible then either.

I have to admit I didn’t read the entire text at first. I find the thoughts that preoccupy you partly trivial. The bed niche for the children is cozy. You can’t see the door from there – that’s optimal.
The WC door is fine as is, the front door has the right size. Too bad you stumble up the stairs when you come in, but that’s still okay. I would actually turn the living room door. I find the TV distance sufficient. The study would be too cramped and cluttered for me.
The bathroom upstairs would be a bit too small for me. It works, but in my dream house I want to be able to move. Storage bunker without windows I find terrible. Especially this narrow nose. That’s not how you plan rooms in new buildings, that’s fiddly. But that’s the only mistake I notice. The cause is the exorbitant wishes on tiny space. That’s what bothers me the most.

Thank you very much for your feedback.
Yes, we have many thoughts preoccupying us. We want it somehow perfect and with the floor plan we still have the opportunity to influence “our house”.

Regarding the office: The furniture (also storage, in particular a 1.5 m wide cabinet) that we want to put there would fit and the distance from the desk to the sideboard on the opposite side would be 90-95 cm, even more than I have in the office of my employer. It’s not a wellness oasis, but it fulfills my employer’s requirements .

Regarding the bathroom: Our current bathroom (with bathtub) is 5 m². You could certainly make it a little bigger if you shrink the storage room and the children’s rooms a bit. But we don’t need a wellness oasis either.

Regarding the storage room: This room was at one point a 1.3 m narrow corridor and another time the shower niche was extended all the way to the children’s room and thus the storage room was completely internal. The thought behind this “narrow nose” is that if the shower is directly next to the children’s room, the child might hear every turning on and off of the shower. Moreover, you could hide the exhaust pipe for the gas boiler and other supply lines in this niche and also put things there that you rarely need, e.g. suitcases. But I will definitely take your suggestion into account.

The cause is the exorbitant wishes on tiny space. That’s what bothers me the most.

But which wish should we give up?
I need the office in order to be able to work from home.
Unfortunately, the house has no gable or hip roof and therefore no additional storage space. Therefore a storage room makes sense from my point of view, doesn’t it?

By the way:
With a flat roof you can work very nicely with skylights in the upper floor hallway.

Thank you very much for this suggestion.
In our apartment we have many roof windows and have had a lot of bad luck with them. A roof window is exposed to rain and snow differently than a normal window. I don’t know if you can compare a skylight to a roof window, but we associate nothing positive with the transitions between roof and window. Therefore we would be glad if we had as few windows in the roof as possible in our house.

You cannot look at the floor plans for your house neutrally. There are things that simply do not fit for everyone.

Piano, 1000 books, 200 pairs of shoes, the XXL sofa, the foosball table, the train set, the wheelchair-accessible ground floor because of Grandpa Hans, etc.
Only you know that. You can submit 20 floor plans that work, but whether they suit you?

Don't take this the wrong way, it's a matter of taste. But I have rarely seen such an ugly detached house from the outside.

A disguised Bauhaus style that completely misses the point of this architectural form.

Besides, I am surprised that a developer puts up with such antics (floor plan changes and having the architect show up so many times).
