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.

I can't say much about the floor plan itself, but regarding the “separation” of the master bedroom, since we have two small children:
You won’t get any sleep even with a sliding door if your partner is sleeping next to 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 incredibly loud and often wake someone up...

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

Maybe a tip regarding space: you can use white, floor-to-ceiling built-in cupboards in the hallway for storage, so the wardrobe room can be removed or made smaller.

Thank you for sharing your experience. Regarding the partition wall, I was more thinking along the lines of a baby monitor or for situations like illness or if someone needs to get up very early. Of course, a separation won’t make sense with children in the bed. But that idea has mostly been discarded since the noise probably would not be sufficiently reduced.
It’s definitely also a consideration of mine whether a child going to the toilet could wake the other. That’s why I decided not to place the bedroom directly next to the bathroom.
Yes, I am also thinking about such cupboards, but it would be a matter of cost since these are custom-made units.

This is my 12th version/configuration, so I have already discarded quite a few ideas. Therefore, I am definitely open to changes. However, so far I like this design the best,

House planning software always has imperfections that affect the results. It is not uncommon for users to develop a kind of "Stockholm syndrome," meaning they become overly attached to the software. For this reason, CAD of any kind should not be used for developing plans, but only for the graphical notation and documentation of design concepts!

E) It’s not that many changes after all. On the ground floor, a partition wall would be added for a bedroom, and on the upper floor, the partition wall between the children’s rooms would be removed, creating a living room with an open kitchen. In theory, you could keep the partition wall, but then the living room would be too small.

On the ground floor, basically all room access goes through the staircase hallway. This makes separating spaces quite impractical—unless you completely close off the staircase and declare that the upper apartment is only accessible via the terrace, but then you would likely plan that differently from the start… I also don’t currently see a nice combined living and dining area on the ground floor, nor do I find the layout appealing for a bedroom with that corner space. I had already mentioned that the narrow corridor plus the parallel passage through the kitchen with an unusual kitchen layout just doesn’t qualify as “well planned” in my opinion. Could you live in it? Surely somehow. Would I build it myself like that? No. Would I be able to improve on it myself? Probably not either 😉

My recommendation remains: When you’re ready to start properly, write down your room program and, if you want, note that you would like the upper floor to be separable as its own apartment or something similar. But keep your own plans on the side and see what the architect creates from that.

In response to the comment

this is the height of ingratitude, because this remark is not unnecessary, but rather accurate, and perfectly summarizes the turnaround to a constructive approach in a compact way. When someone says at 11:30 PM (23:30)

even though they only became a member here on the same day at 10:44 PM (22:44) (and it’s quite obvious that they did not read much before signing up), this means that hundreds of opportunities to learn from the experiences discussed were missed.

At least the idea

is immediately worthy of an end-of-year review 🙂

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

Comments about creating a room program and similar topics are correct but actually out of place in a casual “popcorn” thread. Normally, it is helpful to show a site plan oriented to north, but we don’t even know if there is a North Pole on the planet where Cloudcuckooland is located. At least that place doesn’t have a stop on the Lummerland Railway, and negotiations about exemptions from the regional building regulations can certainly be held with the childish Empress ;-)

My crystal ball still doesn’t see a Mrs. Right who will set Thomas straight. So let’s just keep it playful, because too much seriousness would only get in the way.

This "design" most resembles a teenager playing The Sims. Take a look at functional floor plans and read through the threads here. Then maybe something worth discussing will come out of it...

And statements like these are unnecessary and only intended to provoke.

It is the height of ingratitude when someone can’t even quote properly and makes false accusations.

Because you also have to be registered here to be able to read at all 🙄

I can give you a tip, too. If you think you are being funny, no, you are not.

I don’t really care whether it can ultimately be classified as a two-family house or not (unless there are subsidies tied to that). Since the staircase can be closed off with the sliding door, I don’t see any reason why it couldn’t then be used as two separate apartments.


The living units are not fully separated because the ground floor unit does not have its own bathroom; instead, it is accessible from the common hallway. Every door from the ground floor hallway into the unit should therefore be considered an apartment entrance door, not just a simple interior door.

You don’t see it because you don’t have expertise in this area and haven’t read up on it.

That in itself is not a problem—I have no clue about paragliding, so I simply don’t do it. Or, if I want to try it, I hire an instructor. Applied to residential buildings and floor plans, the instructor is an architect. They create functional floor plans because that’s what they have studied.
