I find it quite practical if part of the closet is only 40 cm deep.
I’ve also thought about that and that’s actually why I came to the conclusion that it’s not so bad if there are only narrow cabinets on one side. At the moment, our shelves in the closet are also just over 40 cm deep (60 cm cabinet, but the shelves are not that deep) and that is completely sufficient. However, I have already planned to possibly hang more clothes in the future (simply for ease of use), so 60 cm cabinets on both sides wouldn’t be bad either. Basically, the dressing room is wide enough for 2 x 60 cm cabinets, and it would be quite good if it could be utilized like that, if possible.
In the kitchen, I would leave out the door and instead make the terrace door at the dining area double size (or even bigger). I think then the south side would also look better from the outside. For that, then (this has already been mentioned here too, I believe), equip that side with kitchen cabinets. Instead of the door, windows or a strip of light above the worktop would be possible. Also wider than the planned terrace door (I would make it along the entire length of the worktop). You get more light that way and it will be brighter.
I think we are talking past each other here or I’m misunderstanding you ops:. The door that definitely should stay is the door from the hallway to the kitchen (interior door), so not the glass door (terrace door) between the kitchen rows leading outside. I had also considered, instead of the glass door, making a window with a sill in the kitchen, also across the entire width. Take a look at my very first post; somewhere in the middle of the text, I also included a modified sketch of the south view. That’s what you meant too, right?
Home office: I also don’t find the rooms upstairs particularly generous in size. How often do you use the home office? If you only work there occasionally and otherwise just store paperwork, you could consider moving the room to the basement (oops, do you have one? I’m not sure now) and give the children’s rooms more space.
As you already noticed, we don’t have a basement. The home office is initially just a "reserve," the actual home office will first be one of the children’s rooms. Since we initially plan on having only one child but don’t know if maybe someday a second child might be planned, we would also like to have an additional home office (the home office according to the floor plan). At first, it is supposed to be used as a hobby room/storage or something similar, or we can leave out the wall between child 1 and the home office for now, as has been suggested here already. The office is only meant to provide us with a place for our exclusively privately used PC and a bit of storage space for files/folders and paperwork, so the size is sufficient.
Bathroom: T-solutions are actually great but not always the best solution. Here, compared to the currently planned washbasins, you have a whole wall free in the T-solution that is not used at all. I would include that. Either put the washbasin there or the toilet, etc. I wouldn’t like the toilet as it is now, directly next to the door, at all.
The bathroom will definitely be arranged differently, that is for sure. The way it was originally designed by the planner is out of the question for us. I also inserted a sketch of a modified version of the bathroom somewhere in the middle of the text in my first post. Take a look at it. This is roughly how we imagine it. It’s not a T-solution, but the toilet is somewhat hidden and the shower is big enough. We also like T-solutions, but for that you definitely need a wider bathroom (ours is rather narrow) or generally a very large bathroom. We visited several model homes with T-solutions where everything seemed cramped and tight to us. Therefore, the T-solution is not an option for us in our bathroom with these dimensions.
Regarding storage space: I think it should be sufficient. Or don’t you think so? We have the utility room with just over 10 m², we also have a few square meters of storage space under the stairs for small stuff like vacuum cleaner/cleaning supplies or crates of drinks or whatever. Then we still have an attic where things that are not used frequently can be stored (Christmas decorations, etc.). And then there’s the storage room behind the garage with about 18 m², where garden furniture, tools, etc., can be stored. We actually thought that should be enough. In addition, we probably will only have one child (that’s the plan anyway). Then the home office would also be available as additional storage space since one of the children’s rooms would be the office. So honestly, we haven’t worried too much about storage space. I actually think most floor plans here in the forum have less storage than we do, so we assumed we shouldn’t have problems with that? Am I so wrong? Of course, I won’t be able to hoard loads of stuff, but I don’t want that either. I see my parents’ basement – roughly 90% of the things in there just belong in the trash.
