Floor plan, not a specific single-family house, approximately 200m² with 2 apartments

No, this is a single wide bed. The door (with a cutout) also runs into the wall and is basically a lying L-shape, so that the bottom edge of the door would barely pass over the mattress.

o_O That’s absurd!
Get yourself a second duvet along with a pillow and store it on the guest fold-out couch. In case of emergency, you switch rooms and have everything ready. It’s not much more effort, but you get a proper spatial and acoustic separation instead of nonsense like a sliding door over the mattress!

- Garages are generally allowed to start at the property boundary, but the use of the area on the garage must comply with the 3m distance rule ... so a fence or similar, so that the 3m to the neighboring property cannot be entered.

How far away the neighboring property ultimately is, I cannot say, but maintaining the 3m distance could be feasible with an appropriately sized plot. Or, if lucky, it might be the last house/property on the street.

- Stairs .. there is a stair layout overview with some minimum dimensions in the

I already looked at that before and my stairs roughly correspond to the stairs at the top right. They are a bit shorter but wider. As I said, I found the stair dimensions like this from a provider. If the stairs then need to be somewhat longer or wider, I could still adjust that. We’re probably only talking about a few centimeters here.

- House connection rooms should always be planned facing the street or so that other building parts do not completely overbuild the entire supply line. At least this should be avoided.

I am aware of that point and mentioned it in my original text. I had considered swapping the utility room and ground floor bathroom, but I wasn’t really happy with either version. I would be willing to bear the additional costs (if allowed), even if the line routing would have to go, for example, around the garage.

- Corridors, yes, one should perhaps make them space-saving, but they should also be planned so that larger pieces can get around the corner and so that a certain friendliness of the house is given.

What would you specifically think of as impossible? On the ground floor you can get through the front door, utility room door, and garden terrace. Upstairs there is a separate front door. The most problematic thing for me would actually be swapping the bed in the bedroom, if the wardrobes are already standing.

- Children's bathroom .. only toilet or what? Where should the children shower? And generally, when planning bathrooms, one should also plan for partition walls etc. for WC wastewater and also consider the floor below.

It would be intended purely for quick toilet visits, whether at night directly before or after sleeping. Otherwise, at most, teeth brushing or just washing hands is planned. The children can of course still use the main bathroom for showering etc. Regarding the pipes, I had thought/assumed that they could also run in the exterior walls, but I would need to inform myself more precisely here. Possibly I would then have to increase the width to about 1.2-1.3m due to the partition wall.

Kitchen .. also engage with planning here. It is always practical to have access to the garden/grill area from the kitchen.

There is a large opening of 1.8x2m from the kitchen to the dining room, from where you can quickly reach the terrace. Therefore, I do not really see the need for an additional direct access from the kitchen.

- Cabinets etc.. it is unsightly to enter houses or rooms and immediately next to the entrance direction there is a tall cabinet (your entrance door). It takes away openness.

For some things, I could have taken the trouble to write the height as well. At the place you mentioned, no cabinet is planned, but a smaller chest of drawers. On it, things like car keys can be placed. Possibly above it the control if it were to be a smart home (another tablet in the living room). The cloakroom would be directly to the right of the entrance area.

- so ... study floor plans, follow the threads here and learn from them ;)

Thanks for the criticism, I take the points to heart. For some things, in my opinion, there is no right or wrong, only preferences.

I just meant that north should be at the top on the map. Unfortunately, you have south at the top.

Oh, yes, you’re right, I could/should still change that. I tried so many different options, moved, rotated, etc., that in the end it looked like it was with the cardinal directions. At the beginning, north was also at the top ^^

Just because you plan a sliding door between two beds doesn't make it any less disturbing for the other person. The sliding door does not reduce any sound.

What added value do you expect from a children's bathroom without a shower?

I also find it strange that a walk-in closet is planned to be larger than a child's room. Of course, one can argue that 12 sqm is enough because it was enough for you yourself. But in a new build with so many square meters, surely more should be possible. Or do all your friends build like that too?

600k for the project will, in my opinion, not be enough.

Regarding the sound insulation of the sliding door, I also have my doubts and therefore marked it as a gimmick. Of course, I would have to test beforehand with a decibel meter how much noise can be suppressed by a sliding door. I doubt that the sliding door eliminates any sound at all; rather, the question would be whether it reduces enough to provide added value.

How often do you go to the toilet and how often do you have to shower? The children would have a somewhat closer, easier way, and the toilet in the main bathroom thus would be free more often. When you are sitting on the toilet, you also want to be alone. Also, the "children's bathroom" wouldn't necessarily have to be fully tiled, making a later remodeling easier when the children move out.

As stated before, the dressing room partly serves as storage space since there is no basement, and its size is largely due to the planning (of the kitchen) from the ground floor. Most plans I have seen have a children's room of 15–20 sqm, but these then only have one or even no office. If the "children's bathroom" were to be omitted, it would also be about 1 sqm larger each.

We have to wait and see how prices develop in the near future. If possible, I would of course try to reduce costs with some self-performance here or there. Your estimate could definitely be accurate if it were completely turnkey.

You have preconceived opinions and you don't really want to play with floor plans, but have already fallen in love with your layout. You can tell from statements like

There is a large opening of 1.8x2m from the kitchen to the dining room which allows quick access to the terrace. Therefore, I don't really see a need for an additional direct access from the kitchen.

And, what is the point of a children's toilet that would also require 2 unmarked entrances, if then the rest goes to the parents' bathroom. It is better to have a central, easily accessible bathroom for all residents of the upper floor. Especially since the toilet drain would end up in the living room ;)

If there is, for example, only a dresser in the entrance, then where do jackets etc. go, especially in a 4-person household with children.

For drawing.. there are standardized drawing variants:
- Tall cabinets drawn as a box with a cross
- Wall cabinets drawn as a box with a diagonal line
- Dressers etc. just drawn as a box

Stairs... here a few cm and there a few cm.. with your two-apartment planning, you also have to remember that beds, sofas, etc. will have to be transported up the stairs. When planning in a sketch, it is better to be a bit generous than too tight.

o_O That is just absurd!
Get yourself a second duvet along with a pillow and store it on the guest fold-out couch. In case of emergency, you change the room and have everything there. That is not much more effort, but then you have a proper spatial and acoustic separation and no botch like a sliding door over the mattress!

Maybe you are right about that, but whether it is really absurd, I don’t necessarily see that way (yet). I would have to somehow test how much noise could actually be generated by it in the end. But it is definitely "abnormal" or not "usual." However, just because something is not usual doesn’t necessarily mean it’s bad.

Personally: Even as someone who cannot really create sensible floor plans themselves, I immediately see too many corners and edges here, none of which really fit. On top of that, supposedly "clever features" were added, which simply do not work in this form. e.g., the children’s bathroom looks like that afterwards, it wasn’t originally there, and then it sounded like a great idea. But building two doors in a <2 sqm bathroom and having the drainpipes going right through the living room is already quite far from a functional plan.

Think again about a room program (what must be included, what might be included) and how you want to live in it, and take that to an architect and/or look at existing plans and whether they fit you. I myself don’t have the ability to create a sensible floor plan out of nothing either, but the nice thing is, I don’t have to ;)

You are absolutely right with the assessment that the "children’s bathroom" wasn’t originally there and I’m considering whether it would make sense or not.
The consideration regarding the drainpipes through the living room is definitely something to think about, but I am not sure how disruptive that really is. After all, the toilet won’t be used that often, especially during the times when the living room is used the most. I would have to talk to someone for whom this case applies.

I have already looked at more than enough plans and 90% of the plans do not appeal to me at all. Everyone has their own ideas/wishes and different conditions have to be met. My wish is simply to create a suitable house that each has 2 children + offices, and that each floor can be considered a separate apartment. Normally you don’t find something like that.
