Preliminary note: This is not a specific building project, but it is something that may happen in the future if possible. Many of my friends have recently built houses and are currently in the process, but for myself it will still take some time. However, since I am quite interested in the subject and have skills in 3D design, I have started to think about how my "dream house" should look. I am fully aware that the floor plan may still change due to the location.

Therefore, I don’t need comments about how planning like this in advance doesn’t make sense. My goal is to see what is roughly possible and reasonable or not, and to gain more experience.

Development plan / restrictions Not available
Client requirements
Style, roof shape, building type: Modern, gable roof, future-oriented
Basement, floors: No basement, 2 floors + attic area for storage
Number of occupants, age: 2 adults + 2 children
Space requirement on ground floor and upper floor: Approximately 90m² (970 sq ft) each
Office: Family use or home office? Yes
Occasional guests per year: Possible but not planned
Open or closed architecture: Rather closed
Conservative or modern construction: Mixed
Open kitchen, kitchen island: Partly, no
Number of dining seats: 2 with couch ^^
Fireplace: No
Music / stereo wall: Probably
Balcony, roof terrace: Yes, yes
Garage, carport: Garage
Utility garden, greenhouse: Possibly garden shed
If possible, the garden should face south, among other reasons because photovoltaics will be used.

House design
Who planned it: Do-it-yourself with Inventor!
What do you especially like: The use of the house for several life phases
What do you dislike? Why? More difficult / expensive utility connections, presumed costs ^^
Price estimate according to architect / planner: Own estimate 600k without land
Personal price limit for the house including equipment: Currently unclear
Preferred heating technology: Air-to-water heat pump

If you have to give up certain details / expansions
- Can give up: Large utility room, changing room
- Cannot give up: Terrace

Why did the design turn out the way it is? For example:

I tried to create a floor plan that keeps the house practical for different stages of life. Both the ground floor and the upper floor can be used as independent apartments with minor modifications, for example when the children are not yet there, when they move out, or if the marriage should break down. Depending on the situation, either one floor or both can be rented out. The garage and utility room remain accessible to both floors. In addition, features such as photovoltaics, KNX (home automation system), empty conduits etc. should prepare the house for the future.
House architectural plan: Floor plans of ground and upper floor, 3D views, and garden.

Take a look at some working floor plans and read through the threads here. Then maybe something will come up worth discussing...
is the height of ingratitude, because this advice is not unnecessary, but rather accurate, and perfectly summarizes the turnaround to a purposeful approach. If someone says at 11:30 pm

even though they became a member here earlier that same day at 10:44 pm (and quite obviously did not do much reading before registering), then hundreds of chances to take in discussed experiences were missed.

At least the idea

The door (with opening) also runs into the wall and is basically a horizontal L shape, so the bottom edge of the door would just barely clear the mattress.
is immediately worthy of a year-end review 🙂

By the way, this approach strongly reminds me of https://www.hausbau-forum.de/threads/einliegerwohnung-fuer-eltern-210-m-efh-und-80-m-elw.24218/ by @schustrik ;-)

Suggestions about creating a room program and the like, while correct, are really out of place in a casual thread. Showing a site plan oriented to north is usually helpful – but we don’t even know if this planet, where Cloud Cuckoo Land is located, has a North Pole at all. At least this place doesn’t even have a stop on the Lummerland railway, and negotiating exemptions from building regulations with the child emperor is certainly possible ;-)

My crystal ball currently does not see a Mrs. Right to set Thomas straight. So, let’s leave it as playing around, and too much seriousness is just disturbing there.

I would recommend that the original poster plan exclusively with drywall on timber studs over a raised floor system. This way, the walls can be relatively easily moved if it turns out that the initial layout doesn’t work.

It’s also best to avoid using screed and instead use a raised floor with joists like in office construction, so that the pipes and cables under the floor can be repositioned as needed.

With this approach, almost everything can be modified later on, except for a few minor points.

Of course, this type of construction also has many disadvantages and can sometimes be more expensive, which is the trade-off to accept.

I can’t say much about the floor plan itself, but regarding the “separation” of the master bedroom, since we have two small children:
Even with a sliding door, you won’t be able to sleep if your partner is next door trying to calm a restless child. The only solution is to move to a different room. We chose a larger bed (180 + 90 cm) (71 + 35 inches) so everyone has more space and a quieter night.

One more tip: elbows, heads, or knees hitting doors or drywall during a restless night are extremely loud and often wake someone up...

Toilets located directly next to bedrooms are also very noisy, especially if the door opens into the bedroom (consider sound insulation ratings...).

Maybe as a space-saving suggestion: in the hallway, you can install white, floor-to-ceiling built-in wardrobes for storage, so the walk-in closet can be eliminated or made smaller.

Maybe @mayglow should clarify that their post is not meant to say "you can keep it."
@ThomasMagmar Just realize that a “nicer” comment among 10 harsh criticisms doesn’t automatically mean: “great, go ahead.”
The design is and remains poor, even with any room changes. The location of the staircase alone means it can’t be considered a two-family house.
There’s no point in sugarcoating or justifying this. These are careless experiments.
I’m out.

It’s not about what kind of criticism you give, but how you give it. For example, you can describe something as "unsuitable/inappropriate" or just say it’s "bad." Although I welcome and appreciate the feedback, as I said, I feel some were only aiming to put me down.
The main criticism I received was regarding the partition wall in the bedroom and the “children’s bathroom.” I understand the concerns and negative points on both, which had been raised before, and I might discard those ideas. I will also make two or three adjustments to how the floor plan is presented. However, so far I haven’t heard any convincing arguments on the other points that seem reasonable to me.

In principle, I don’t care whether it ends up being called a two-family house or not (as long as no subsidies depend on it). Since the staircase can be closed off with a sliding door, I don’t see why it couldn’t be used as two separate apartments.

We once had a walk-in closet with a sliding door in the bedroom, custom-made by a carpenter. Since we got up at different times, we thought it would be convenient to pick out clothes quietly in the morning and get dressed after showering. But the sliding door made noise regardless, even with a floor track and a damper at the end. The loudest noise was when it was pulled fully shut to ensure it was completely closed. It didn’t help much—we could hear everything inside the closet just as clearly as if there were no door, only somewhat muffled.

Looking back, we could have invested the money for the custom door better elsewhere.

Okay, thanks for sharing your experience. The noise from moving the door wouldn’t be a big issue for me, but the fact that it barely reduces noise in the end is definitely a strong argument against it. How thick was the door, and was it specifically designed as a sound-insulating door?

The noise issue with sliding doors is not related to the door panel itself. It comes from the fact that in most systems, the door panel does not press tightly against a frame or jamb. Essentially, the door panel floats freely within the track system, resting only on the rollers, which allows air (and therefore sound) to pass around it easily. Not to mention the transmission of structural noise...

There are specialized systems designed to address this, but they are typically at least four times more expensive. I also doubt that such systems exist for applications like room dividers or separating beds.

In some cases, a heavy theater curtain might actually absorb more sound than a sliding door.
